Flocculants used in municipal wastewater treatment plants are mainly the following categories: organic flocculants, inorganic flocculants, polymer flocculants and composite flocculants, these flocculants can effectively deal with the suspended solids, sediments and colloidal substances in the municipal wastewater, so as to achieve the purpose of purifying water quality. 1, organic flocculants: organic flocculants mainly through its molecular chain of active groups and sewage in the suspended solids and colloidal substances occurring the role of its coagulation and settlement. Organic flocculants commonly used are
polymeric aluminium chloride (PAC) and polymeric aluminium chloride coagulation enhancement agent (PAC-G) and so on. These organic flocculants have the characteristics of fast coagulation speed, no residue, etc., which can effectively remove the colloidal substances in the urban wastewater and improve the water quality. 2, inorganic flocculants: inorganic flocculants generally exist in the form of metal salts, mainly through the chemical reaction with the suspended and colloidal substances in the sewage to form a precipitate, thus playing a flocculating effect. Commonly used inorganic flocculants are aluminium sulphate,
aluminium sulphate polymer and
ferric chloride. These inorganic flocculants have the characteristics of low cost, stable effect, etc., which can be used to deal with the suspended and colloidal substances in sewage. 3, polymer flocculant: polymer flocculant refers to the polymer with long molecular chain structure, through the adsorption and coagulation with the suspended and colloidal substances in the sewage, the formation of large particles of flocculants. Polymer flocculants commonly used
polyacrylamide (PAM) and polyacrylamide modified polymers. These polymer flocculants have the characteristics of fast flocculation speed, coagulation of a variety of suspended solids, etc., which can be widely used in municipal wastewater treatment plants. 4、Compound flocculant: Compound flocculant is a mixture of many kinds of flocculants, forming a mixture with good flocculation effect. Commonly used composite flocculants are polymeric aluminium chloride and polymeric aluminium sulphate mixed use, aluminium sulphate and polymeric ferric chloride mixed use and so on. These composite flocculants combine the advantages of various flocculants and can remove suspended and colloidal substances in sewage in a short time. The main types and characteristics of flocculant application in urban wastewater treatment plant introduced by the above flocculant manufacturer for urban wastewater treatment plant. In the specific application process, according to different water quality and treatment requirements, different types of flocculants can be selected or mixed to achieve better treatment results. In addition, the amount of flocculant used, the dosing method and other factors should be considered to ensure the effective use of flocculants and economy.
