How do you add? Poly aluminum is a solid liquid? If you add the correct method, not a floc, continue to adjust ph to 8 or more, try again, if not yet floc, simp
Can be used at the same time, in general, the first vote to add poly aluminum to form flocs, and then add polyacrylamide flocs increase.
Need to cooperate with PAM. Therefore, only the PAC is definitely not work, polyaluminum chloride low molecular weight, can not be brought through the filter cl
Put more calcium aluminate powder is strong alkali weak acid salt, ph value is higher, the release is mainly used to adjust the pH of polyaluminum chloride
It is through flocculation, precipitation and thus achieve the purpose of water purification, the price is relatively polyacrylamide 8000-20000 yuan & # 47; and
