[usage] (1) as oil field surface water treatment flocculant, can remove the suspended solid in the water, for life or production. The product has the advantage of cheap, usually used with polyacrylamide. Aluminum sulfate dosing quantity of 20 ~ 50 mg/L, PAM dosing quantity is 2 ~ 5 mg/L.
(2) used for oilfield oily wastewater treatment. When the sewage is neutral or alkaline, to remove suspended solids in water or oil has certain effects; But when the pH is low, the treatment effect is bad, often need to adding the lime milk to adjust pH value. Aluminum sulfate dosage generally 50 ~ lOOmg/L.
