  • Why is flocculation important in industrial wastewater treatment?
  • Flocculation is an essential phenomenon in industrial wastewater treatment. Inorganic coagulants (salts of multivalent metals) are being commonly used due to its low cost and ease of use. However, their application is constrained with low flocculating efficiency and the presence of residue metal concentration in the treated water.
  • Why are flocculants used in water treatment?
  • Flocculation leading to sedimentation is both used in the purification of drinking water, as well as for sewage, storm water, and industrial wastewater treatment. This is why flocculants are largely known for being water treatment plant chemicals. How do flocculants work?
  • Can biopolymer based flocculants be used for sludge dewatering?
  • Recently, the application of biopolymer-based flocculants in the flocculation for sludge dewatering is a hot research direction. Compared with traditional inorganic coagulants and synthetic organic flocculants, biopolymer-based flocculants have a higher sludge dewatering efficiency and wider pH adaptability.
  • Can biopolymer based flocculants reduce turbidity removal cost?
  • With the aid of biopolymer-based flocculants in the coagulation process for turbidity removal, the dosage of inorganic coagulants can be reduced. Thus, it can reduce the environmental risk and water treatment cost brought by inorganic coagulants.
