Coal washing plant sewage treatment agent anionic polyelectrolyte

Recently, customers form coal washing plants consult polyacrylamide for coal washing. Our technicians collect sewage samples and analyze them on site, the pH of coal washing plant wastewater is alkaline. Before treating this wastewater, we need to adjust the pH of the wastewater to neutral. According to the nature of sewage, we choose suitable polyelectrolyte products. We need to use anionic polyelectrolytes with molecular weights between 8 million and 18 million, also can be used nonionic polyacrylamide or cationic polyacrylamide. In the whole process of washing coal, we need to use many types of chemical agents, such as foaming agents, flotation agents, defoamers, water, heavy liquids, in the subsequent treatment we need to use polyelectrolytes and polyaluminum chloride and so on. Polyelectrolyte is generally used as a flocculant, polyaluminum chloride is used as a coagulant. The two chemicals can be used alone or in combination. Many experiments have proved that the combination of the two chemicals is better. When the cementation of the slime is severe, only the flocculant is used poorly, so it is necessary to add a coagulant to break the colloid first, and then use polyelectrolyte. Many cases have proved that the use of polyelectrolyte for treatment of sewage in coal washing plants can accelerate the sedimentation of coal slime. The polyelectrolytes produced by our company can be divided into anionic polyelectrolytes, cationic polyelectrolytes and non-ionic polyelectrolytes according to ionic types, which can be applied in many fields. The main products of flocculant manufacturer Xinhuan Water Treatment are: White polyaluminium chloride (food grade), drinking grade polyaluminium chloride, industrial grade polyaluminium chloride, anionic polyacrylamide, cationic polyacrylamide, nonionic polyacrylamide, petroleum recycling polyacrylamide, oil recovery polyacrylamide, polyacrylamide, polymer flocculant polymer flocculation coagulant, polymeric ferrous sulphate, polymerized iron and aluminium chloride, and other water treatment chemicals.
