Potable water chemicals

Unlined cast-iron and steel pipes for water distribution installed between 1930 and the late 1950s promote significant disinfectant demand in some sections of the distribution system. The demand can be divided into two major categories:

•   the demand of the bulk fluid, and
•   the demand of the pipe wall surface.


The disinfectant demand of the bulk fluid is exerted by reactions with organic, inorganic, and bacterial constituents of the water. Reactions with corrosion products, oxidation of dissolved iron originating from the pipe walls, biofilms that reside on the pipe surface, and the organic and inorganic constituents that accumulate within the corrosion product-biofilms matrix cause disinfectant demand.

Loss of disinfectant residual, especially in low-flow areas, increases biofilms accumulation, nitrification, and customer complaints about objectionable taste and odor, color, and particles in the water.

We are offer potable water treatment chemicals. Our recommended products are approved for use in drinking water systems by the National Sanitation Foundation (NSF); the nationally recognized health effects standard for chemicals which are used to treat drinking water.
If you need a uniquely qualified supplier of potable water treatment chemicals to fit your specific water quality needs, we can help you. Our services include professional consultation, water analysis, product selection, dosage rates, and technical support from AWT experienced advisors.
