Poly aluminum chloride control four major problems of drinking water disinfection

Poly aluminum chloride in the filter effect of enhanced coagulation control four major problems of drinking water disinfection.

Enhanced Coagulation can effectively remove natural organic matter, to control the purpose of drinking water disinfection byproducts, poly aluminum chloride(PAC) has cast provinces, without the construction of new structures and low running costs for the transformation of the original system, in development worth promoting. However, the application of enhanced coagulation also brought some problems:

Because large doses of coagulant dosing, sludge generated by the treatment system, although increased, the original sludge dewatering system capacity will be insufficient; enhanced coagulation conditions, there may be less than ideal turbidity removal efficiency thereby increasing the filter running burden.

Increase the total drug consumption, including adjusting the pH of the coagulation and the consumption of sulfuric acid corrosion problem considering the finished water increases the pH of the consumption of soda lime.

Hugh impurity particles and on the removal of negative pathogens, to improve the dissolved organic matter, COD removal capacity limited, ammonia, mineral oil removal no role in promoting.

Of raw water for a particular characteristic of the selected type of coagulant, pH and increasing the dose, etc., do not necessarily have all the raw water quality work.
