【Abstract】 A new kind of inorganic polymer water clarifying agent polyaluminum sulfate containing polybasic ions (MPAS) and its production process are introduced. The flocculating characteristics of MPAS are detected, and the conditions are investigated experimentally in order that MPAS possesses the best flocculating performance and chemical stability. The final experimental results show that MPAS is superior to the traditional water clarifying agent polyaluminum sulfate and aluminum sulfate in flocculating performance and chemical stability.更多还原
