How turbidity meter used in water plant?

Turbidity meter is mainly used in water plant of water quality inspection, mainly used to measure turbidity of water inlet and outlet. Through numerical real-time monitoring of turbidity, enables customers to better monitor the import and export of tap water turbidity value. Using distilled water turbidity meter is to reduce the ion exchange of organic matter to determine the effect of pure water, and reducing the growth of bacteria in pure water. Hydrazine sulfate and six methyl tetramine can fit into a silica gel in the dryer for the night and then weighing. Turbidity meter within 12 ~ 37 ℃, reaction temperature of ( Foer horse hydrazine) The generation of turbidity had no obvious effect, temperature & lt; 5 ℃ without polymer formation. Therefore, dispensing foer horse hydrazine turbidity standard stock solution, in general can be at room temperature. But low reaction temperature, mixing suspension easy to glassware adsorption, the temperature is too high, can cause high turbidity standard decline. Foer horses, therefore, the production of hydrazine zui good control in 25 + / - 3 ℃ temperature. Hydrazine sulfate with six methyl tetramine reaction time to 16 h is nearing completion, 24 h reaction products of turbidity da zui big value, no difference in 24 ~ 96 h. Fore the generation of hydrazine, when the pH of aqueous solution is 5. 3 - 5. 4, show cricoid grain and uniform fine; PH 6. 0, and flocculent particles are close photo; PH 6. 6, the formation of large, medium and small different snowflake particles. Turbidity is 400 degrees of standard liquid can be preserved in January ( In the refrigerator can save half a year) , turbidity is 5 ~ 100 degree of standard liquid without change within 1 week. Tap water turbidity should be expressed in NTU scattering turbidity unit, no more than 3 NTU, special circumstances should not be more than 5 NTU. Many production water turbidity is quite important. The application of surface water beverage factory, food processing plants and water treatment plants, generally rely on coagulation, sedimentation and filtration to ensure to provide satisfactory products. The suspended material concentration along the turbidity and difficult to have a relationship, because the particle size, shape and refractive index influences the optical properties of the slurry. In the measurement of turbidity, glass are in contact with the sample should be kept in clean condition.
