About wastewater treatment flocculants

Flocculants are used as a means of strengthening solid-liquid separation in the field of sewage treatment. They can be used to strengthen the primary sedimentation of sewage, flotation treatment and secondary sedimentation after activated sludge process, and can also be used for tertiary treatment or advanced treatment of sewage. When used for conditioning before dehydration of excess sludge, flocculants and coagulants become sludge conditioners or dehydrating agents.

The flocculant for wastewater treatment is a non-toxic organic polymer flocculant with a positive charge (active group), which can effectively coagulate suspended organic colloids and organic compounds. The dosing concentration depends on the turbidity of the raw water. The most suitable flocculant The dosage should be determined by the test of the water sample, too much or too little dosage will reduce the filtering effect. Special attention should be paid to anti-scaling flocculants with opposite properties will cause coagulation reaction, leading to serious membrane pollution. This flocculant is compatible with flocculant for wastewater treatment; the pH range of influent water is 5-8; it can be added directly or after dilution; Inorganic flocculants are used together for better results.
