The unrefined wine is treated with fining agents to reduce cloudiness. This cloudiness is what winemakers refer to as protein haze, or haze for short. Thaumatin-like proteins (TLPs) and chitinases are the primary grape proteins responsible for haze formation. These positively charged proteins degenerate and stick together, resulting in undesirable flocculent clouds and visible haziness.\u003c\/p\u003e\n\u003cp\u003eThe prevention of protein haze or deposit in bottled white wines is a universal concern and often a wine needs to be stabilized before bottling. One commonly used stabilization agent is bentonite. Bentonite is a volcanic clay earth type fining agent (like kaolin). It improves the clarity and stability of wine but has also negative aspects because of the volume of lees formed, reduction of tannin and color. Since there are different types and qualities of bentonite with different capacity of protein removal, it is important to make laboratory trials with the same lot and wetting degree of the bentonite as that will be used in the cellar.\u003c\/p\u003e\n\u003cp\u003eProtein stabilization is normally not a problem in bottled red wines because of the relatively high concentration of phenols that binds and precipitates with the unstable proteins before bottling. Often bentonite is added to red wines at a level of about 12 g\/hL (1 lb\/1000 gal), reducing colloidal suspended particles thus improving membrane filterability.\u003c\/p\u003e\n\u003cp\u003eWines with low phenols contents, such as rose, light reds and whites should be checked for protein stability before bottling. Hanna offers a rapid test to verify the risk of future protein haze formation. If protein instability is detected, a next test can help defining the right amount of bentonite to be added for improving protein stability. It is important not to overdose bentonite, avoiding stripping wine flavour, body, and significant loss of color, especially in young red wines. Moreover, adding only the necessary amount of bentonite to obtain the desired protein stability results in a reduction of costs.\u003c\/p\u003e\n\u003cp\u003eWinemakers can determine the initial turbidity of the unrefined wine with the HI83749. After taking a turbidity reading the pre-made HI83749-20 Bentocheck Solution is added to the wine sample. A second turbidity measurement is taken. If the second turbidity reading is less than the initial turbidity reading plus 2 NTU, the wine can be considered stable. Otherwise a fining trial can be performed to determine the amount of bentonite that must be added to stabilize the wine.\u003c\/p\u003e\n\u003ch5\u003ePrincipal of Operation\u003c\/h5\u003e\n\u003cp\u003eTo measure turbidity the HI83749 passes a light beam through the sample that is scattered in all directions. The intensity and pattern of the scattered light is affected by many variables, such as wavelength of the incident light, particle size and shape, refractive index, and color. The optical system of the HI83749 includes a tungsten filament lamp, a scattered light detector (90°) and a transmitted light detector (180°).\u003c\/p\u003e\n\u003cp\u003eThe HI83749 features a powerful microprocessor that calculates the NTU value from the signals that reach the two detectors. An effective algorithm is used to correct and compensate for any color interferneces. The optical system and measuring technique also compensate for fluctuations in lamp intensity, minimizing the need for frequent calibration.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-wrap: wrap; align-items: center; justify-content: center; gap: 24px 48px; margin: 0 0 48px; flex-direction: row-reverse;\"\u003e\n\u003cdiv style=\"flex: 1 1 260px; max-width: 440px; text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/HI98703_5reagents.jpg\" alt=\"reagents\" loading=\"lazy\" style=\"display: block; max-width: 100%; height: auto; margin: 0 auto;\"\u003e\u003c\/div\u003e\n\u003cdiv style=\"flex: 1 1 340px; min-width: 0;\"\u003e\n\u003cp\u003eThe HI83749-11 AMCO AEPA-1 standards ensure that measurements are traceable to primary reference materials.

Once considered as a mostly aesthetic characteristic of drinking water, significant evidence exists that controlling turbidity is a competent safeguard against pathogens. In natural water, turbidity measurements are taken to gauge general water quality and its compatibility in applications involving aquatic organisms. The monitoring and treatment or wastewater was once solely based on the control of turbidity. Currently, the measurement of turbidity at the end of the wastewater treatment process is necessary to verify that the values are within regulatory standards.\u003c\/p\u003e\n\u003cp\u003eTurbidity of water is an optical property that causes light to be scattered and absorbed, rather than transmitted. The scattering of light that passes through a liquid is primarily caused by the suspended solids present. The higher the turbidity, the greater the amount of scattered light. Even a very pure liquid will scatter light to a certain degree, as no solution will have zero turbidity.\u003c\/p\u003e\n\u003cp\u003eDrinking water treatment plants that obtain water from surface water are required by the EPA to monitor and report the turbidity.

Once considered as a mostly aesthetic characteristic of drinking water, significant evidence exists that controlling turbidity is a competent safeguard against pathogens. In natural water, turbidity measurements are taken to gauge general water quality and its compatibility in applications involving aquatic organisms. The monitoring and treatment or wastewater was once solely based on the control of turbidity. Currently, the measurement of turbidity at the end of the wastewater treatment process is necessary to verify that the values are within regulatory standards.\u003c\/p\u003e\n\u003cp\u003eTurbidity of water is an optical property that causes light to be scattered and absorbed, rather than transmitted. The scattering of light that passes through a liquid is primarily caused by the suspended solids present. The higher the turbidity, the greater the amount of scattered light. Even a very pure liquid will scatter light to a certain degree, as no solution will have zero turbidity.\u003c\/p\u003e\n\u003cp\u003eDrinking water treatment plants that obtain water from surface water are required by the EPA to monitor and report the turbidity.

Once considered as a mostly aesthetic characteristic of drinking water, significant evidence exists that controlling turbidity is a competent safeguard against pathogens. In natural water, turbidity measurements are taken to gauge general water quality and its compatibility in applications involving aquatic organisms. The monitoring and treatment or wastewater was once solely based on the control of turbidity. Currently, the measurement of turbidity at the end of the wastewater treatment process is necessary to verify that the values are within regulatory standards.\u003c\/p\u003e\n\u003cp\u003eTurbidity of water is an optical property that causes light to be scattered and absorbed, rather than transmitted. The scattering of light that passes through a liquid is primarily caused by the suspended solids present. The higher the turbidity, the greater the amount of scattered light.

Once considered as a mostly aesthetic characteristic of drinking water, significant evidence exists that controlling turbidity is a competent safeguard against pathogens. In natural water, turbidity measurements are taken to gauge general water quality and its compatibility in applications involving aquatic organisms. The monitoring and treatment or wastewater was once solely based on the control of turbidity. Currently, the measurement of turbidity at the end of the wastewater treatment process is necessary to verify that the values are within regulatory standards.\u003c\/p\u003e\n\u003cp\u003eTurbidity of water is an optical property that causes light to be scattered and absorbed, rather than transmitted. The scattering of light that passes through a liquid is primarily caused by the suspended solids present. The higher the turbidity, the greater the amount of scattered light. Even a very pure liquid will scatter light to a certain degree, as no solution will have zero turbidity.\u003c\/p\u003e\n\u003cp\u003eThe ISO standard for turbidity measurement uses infrared wavelength of light that is outside the visible spectrum. The primary benefit of the ISO method over the EPA method is the reduction of color interference. The EPA method uses a tungsten lamp that produces light that contains all of the visible wavelengths of light that we see as white. A solution that is colored will be adsorbed by a complementary wavelength of light which will affect the turbidity reading. Since the ISO method is outside the visible wavelength of light the color in the sample does not interfere with the measurement. The USEPA prefers the tungsten lamp since it provides for better accuracy at low ranges and drinking water should not be colored. The requirements of an optical turbidity meter according to\u003ca href=\"https:\/\/www.iso.org\/obp\/ui\/#iso:std:iso:7027:-1:ed-1:v1:en\" target=\"_blank\" rel=\"noopener\"\u003e\u003cstrong\u003e ISO 7027\u003c\/strong\u003e\u003c\/a\u003e are dependent on the measurement range. The measurement of diffuse radiation is typically for low range turbidity measurements (i.e. drinking water) with measurements expressed as formazin nephelometric units (FNU). The measurement of attenuation of radiant flux is for highly turbid samples (i.e. polluted water) and the measurements are expressed as formazin attenuation units (FAU).

Once considered as a mostly aesthetic characteristic of drinking water, significant evidence exists that controlling turbidity is a competent safeguard against pathogens. In natural water, turbidity measurements are taken to gauge general water quality and its compatibility in applications involving aquatic organisms. The monitoring and treatment or wastewater was once solely based on the control of turbidity. Currently, the measurement of turbidity at the end of the wastewater treatment process is necessary to verify that the values are within regulatory standards.\u003c\/p\u003e\n\u003cp\u003eTurbidity of water is an optical property that causes light to be scattered and absorbed, rather than transmitted. The scattering of light that passes through a liquid is primarily caused by the suspended solids present. The higher the turbidity, the greater the amount of scattered light. Even a very pure liquid will scatter light to a certain degree, as no solution will have zero turbidity.\u003c\/p\u003e\n\u003cp\u003eThe ISO standard for turbidity measurement uses infrared wavelength of light that is outside the visible spectrum. The primary benefit of the ISO method over the EPA method is the reduction of color interference. The EPA method uses a tungsten lamp that produces light that contains all of the visible wavelengths of light that we see as white. A solution that is colored will be adsorbed by a complementary wavelength of light which will affect the turbidity reading. Since the ISO method is outside the visible wavelength of light the color in the sample does not interfere with the measurement. The USEPA prefers the tungsten lamp since it provides for better accuracy at low ranges and drinking water should not be colored.

Clarity can be affected by haze, or insoluble or semi-soluble particulate matter which is small enough to form a colloidal suspension in beer, typically less than 2 mm. These particles scatter transmitted light and are observed as a degradation in the brilliance of the beer. To assure consistent product quality, the brewmaster needs more than visual inspection.\u003c\/p\u003e\n\u003cp\u003eSeveral substances can cause haze in beer, but the most frequently encountered problem is due to a cross-linking of polyphenols and proteins. These materials exist in equilibrium in beer and manifest themselves as a haze when they combine to form insoluble colloids. A range of stabilization treatments is available for avoiding haze problems, and the product has to be controlled in several steps during the brewing process, particularly after filtration and before the beer enters the bright tanks.\u003c\/p\u003e\n\u003cp\u003eThe HI847492 Haze Meter reports the measurements in FTU (Formazin Turbidity Units).

Once considered as a mostly aesthetic characteristic of drinking water, significant evidence exists that controlling turbidity is a competent safeguard against pathogens. In natural water, turbidity measurements are taken to gauge general water quality and its compatibility in applications involving aquatic organisms.\u003c\/p\u003e\n\u003cp\u003eChlorine is one of the most commonly used disinfectants for water treatment. It can be added to in various forms including calcium hypochlorite, sodium hypochlorite, or in some instances, chlorine gas. When added to water, chlorine creates hypochlorous acid (HOCl) which dissociates into hypochlorite ion (OCl\u003csup\u003e-\u003c\/sup\u003e).\u003c\/p\u003e\n\u003cp\u003eHOCl ↔ H\u003csup\u003e+\u003c\/sup\u003e + OCl\u003csup\u003e-\u003c\/sup\u003e\u003c\/p\u003e\n\u003cp\u003ehypochlorous acid ↔ hydrogen ion + hypochlorite ion\u003c\/p\u003e\n\u003cp\u003eHOCl is the form of chlorine that acts as a stronger disinfectant as compared to OCl\u003csup\u003e-\u003c\/sup\u003e. To ensure the added chlorine is effective at sanitizing, the pH of the water must be taken into account. Around pH 7.5, HOCl and OCl\u003csup\u003e-\u003c\/sup\u003e are present in relatively equal amounts. Below pH 7.5, the equilibrium shifts to favor HOCl; above pH 7.5, the equilibrium shifts to favor OCl-. Depending on the application, addition of chlorine is effective when added to water with a neutral or slightly acidic pH value.\u003c\/p\u003e\n\u003cp\u003eWhen chlorine is first added to water, it is available as free chlorine. The measurement of free chlorine signifies the amount available for disinfection. Once chlorine begins to sanitize bacteria and pathogens present in the water, it becomes combined chlorine; combined chlorine is no longer available to act as a disinfectant. The measurement of total chlorine signifies the amount of free chlorine and combined chlorine. With both free and total chlorine measurements, a drinking water operator or pool owner can determine if there is enough chlorine available for disinfection.\u003c\/p\u003e\n\u003cp\u003eCyanuric acid is best known as a stabilizing reagent for chlorine. It is widely applied in swimming pool and spa treatment programs to slow down the decomposition of hypochlorous acid. In outside pool areas, this process is accelerated by the effects of UV rays. When applied properly it can save up to 80% of normal chlorine consumption in pools during peak months.\u003c\/p\u003e\n\u003cp\u003eBromine is less volatile and more stable than chlorine, making it a good choice as a disinfectant in pools, spas, and hot tubs, and a sanitizing agent in drinking water systems. Like chlorine, excess amounts of bromine in water can be dangerous to health and can cause eye irritation. Daily monitoring of bromine concentration prevents damage to equipment and contributes to the optimization and efficiency of the process while providing for increased user safety.\u003c\/p\u003e\n\u003cp\u003eIron is naturally present in water in low concentrations, but it reaches high concentrations in wastewater effluents. The iron concentration in water needs to be monitored because it becomes harmful above certain levels. In domestic water, for instance, iron can stain laundry, damage kitchenware, favor the growth of certain bacteria, and unpleasantly alter the taste of water. Iron is also an indicator of ongoing corrosion in water cooling and heating systems. Moreover, iron is normally monitored in mining wastewater to avoid contamination.\u003c\/p\u003e\n\u003ch2\u003ePrinciple of Operation\u003c\/h2\u003e\n\u003cp\u003eWhen measuring turbidity, the light beam that passes through the sample is scattered in all directions. The intensity and pattern of the scattered light is affected by many variables, such as wavelength of the incident light, particle size and shape, refractive index, and color. The optical system of the HI93102 includes an LED light source and a scattered light detector (90°).\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-wrap: wrap; align-items: center; justify-content: center; gap: 24px 48px; margin: 0 0 48px;\"\u003e\n\u003cdiv style=\"flex: 1 1 260px; max-width: 440px; text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/Screen_Shot_2016-04-27_at_1.48.28_PM.png\" alt=\"turbidity measurement\" loading=\"lazy\" style=\"display: block; max-width: 100%; height: auto; margin: 0 auto;\"\u003e\u003c\/div\u003e\n\u003cdiv style=\"flex: 1 1 340px; min-width: 0;\"\u003e\n\u003ch2 style=\"margin-top: 0;\"\u003ePrinciple of Operation: Colorimetric Mode\u003c\/h2\u003e\n\u003cp\u003eWhen measuring specific ions in colorimetric mode, a parameter-specific reagent is added to the sample, displaying a color change; the greater the concentration, the deeper the color. The associated color change is then colorimetrically analyzed according to the Beer-Lambert Law. This principle states that light is absorbed by a complementary color, and the emitted radiation is dependent upon concentration. For determination of free and total chlorine, cyanuric acid, pH, iodine, bromine, and low range iron, a narrow band interference filter at 525 nm (green) allows only green light to be detected by the silicon photodetector and omits all other visible light emitted from the light source.

Clarity can be affected by haze,  an insoluble or semi-soluble particulate matter which is small enough to form a colloidal suspension in beer. These particles scatter transmitted light and are observed as a degradation in the brilliance of the beer. To assure consistent product quality,  the brewmaster needs more than visual inspection.\u003c\/p\u003e\n\u003cp\u003eSeveral substances can cause haze in beer,  but the most frequently encountered problem is due to a cross-linking of polyphenols and proteins. These materials exist in equilibrium in beer and manifest themselves as a haze when they combine to form insoluble colloids.

Once considered as a mostly aesthetic characteristic of drinking water,  significant evidence exists that controlling turbidity is a competent safeguard against pathogens. In natural water,  turbidity measurements are taken to gauge general water quality and its compatibility in applications involving aquatic organisms. The monitoring and treatment or wastewater was once solely based on the control of turbidity. Currently,  the measurement of turbidity at the end of the wastewater treatment process is necessary to verify that the values are within regulatory standards.\u003c\/p\u003e\n\u003cp\u003eTurbidity of water is an optical property that causes light to be scattered and absorbed,  rather than transmitted. The scattering of light that passes through a liquid is primarily caused by the suspended solids present. The higher the turbidity,  the greater the amount of scattered light. Even a very pure liquid will scatter light to a certain degree,  as no solution will have zero turbidity.\u003c\/p\u003e\n\u003cp\u003eThe ISO standard for turbidity measurement uses infrared wavelength of light that is outside the visible spectrum. The primary benefit of the ISO method over the EPA method is the reduction of color interference. The EPA method uses a tungsten lamp that produces light that contains all of the visible wavelengths of light that we see as white. A solution that is colored will be adsorbed by a complementary wavelength of light which will affect the turbidity reading. Since the ISO method is outside the visible wavelength of light the color in the sample does not interfere with the measurement. The USEPA prefers the tungsten lamp since it provides for better accuracy at low ranges and drinking water should not be colored. The requirements of an optical turbidity meter for the measurement of diffuse radiation used in low range measurements (i.e. drinking water) expressed as formazin nephelometric units (FNU) according to ISO 7027:1999 are:\u003c\/p\u003e\n\u003ch5\u003eMeasurement of diffuse radiation for water with low turbidity (0 FNU to 40 FNU)\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003eThe wavelength of the incident radiation shall be 860 nm.\u003c\/li\u003e\n\u003cli\u003eThe spectral bandwidth of the incident radiation shall be less than or equal to 60 nm.\u003c\/li\u003e\n\u003cli\u003eThere shall be no divergence from parallelism of the incident radiation and any convergence shall not exceed 1.5o.\u003c\/li\u003e\n\u003cli\u003eThe measuring angle,  theta,  between the optical axis of the incident radiation and that of the diffused radiation shall be 90o ±2.5o.\u003c\/li\u003e\n\u003cli\u003eThe aperture angle should be between 20o and 30o in the water sample.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eThe HI93703 meets and exceeds the meter criteria specied by ISO 7027.\u003c\/h5\u003e\n\u003ch2\u003ePrinciple of Operation\u003c\/h2\u003e\n\u003cp\u003eThe light beam that passes through the sample is scattered in all directions.

Once considered as a mostly aesthetic characteristic of drinking water, significant evidence exists that controlling turbidity is a competent safeguard against pathogens. In natural water, turbidity measurements are taken to gauge general water quality and its compatibility in applications involving aquatic organisms. The monitoring and treatment or wastewater was once solely based on the control of turbidity. Currently, the measurement of turbidity at the end of the wastewater treatment process is necessary to verify that the values are within regulatory standards.\u003c\/p\u003e\n\u003cp\u003eTurbidity of water is an optical property that causes light to be scattered and absorbed, rather than transmitted. The scattering of light that passes through a liquid is primarily caused by the suspended solids present. The higher the turbidity, the greater the amount of scattered light. Even a very pure liquid will scatter light to a certain degree, as no solution will have zero turbidity.\u003c\/p\u003e\n\u003cp\u003eThe ISO standard for turbidity measurement uses infrared wavelength of light that is outside the visible spectrum.

A solution that is colored will be adsorbed by a complementary wavelength of light which will affect the turbidity reading. Since the ISO method is outside the visible wavelength of light the color in the sample does not interfere with the measurement.

Once considered as a mostly aesthetic characteristic of drinking water, signi˜ficant evidence exists that controlling turbidity is a competent safeguard against pathogens. In natural water, turbidity measurements are taken to gauge general water quality and its compatibility in applications involving aquatic organisms. The monitoring and treatment or wastewater was once solely based on the control of turbidity. Currently, the measurement of turbidity at the end of the wastewater treatment process is necessary to verify that the values are within regulatory standards.\u003c\/p\u003e\n\u003cp\u003eTurbidity of water is an optical property that causes light to be scattered and absorbed, rather than transmitted. The scattering of light that passes through a liquid is primarily caused by the suspended solids present. The higher the turbidity, the greater the amount of scattered light. Even a very pure liquid will scatter light to a certain degree, as no solution will have zero turbidity.\u003c\/p\u003e\n\u003cp\u003eDrinking water treatment plants that obtain water from surface water are required by the EPA to monitor and report the turbidity.

This method offers a high linearity on the low range but is more sensitive to lamp intensity fluctuations. The lower detection limit of a turbidimeter is determined by stray light that is detected by the sensors but not caused by light scattering from suspended particles.
