The flocculant in sewage treatment is a chemical formed by the solid particles that promote the solid in the water into a larger sedent or suspension. Different types of flocculants can have different components. The following are some common sewage treatment flocculant composition:
Inorganic flocculant: Inorganic flocculants mainly include iron and aluminum salt. Common iron sulfate, iron chloride, polymer aluminum chloride, etc. These inorganic flocculants are interacted with the charge of the suspended substance surface to form flocculation reunion to make it easy to deposit.
Organic flocculant: Organic flocculants are generally polymer polymers. Common polyacrylamide (PAM), polymer aluminum chloride, and polyacrylamide cluster (PAC). Organic flocculants have adsorbed and bridge couplet with suspended substances to form a large flocculant, which is convenient for precipitation.
Natural flocculant: Some natural substances can also be used as flocculants, such as starch and gelatin. These natural flocculants are generally suitable for small -scale sewage treatment or flocculation effects under special circumstances.
You need to choose the appropriate flocculant according to the specific sewage treatment and water quality characteristics to obtain a good flocculation effect and precipitation performance. At the same time, different types of flocculants also need to control appropriate addition and mixed conditions during the operation to ensure the best flocculation effect.
