What is a bio-based flocculant?

Polymer flocculants are used to promote solid–liquid separation processes in potable water and wastewater treatment. Recently, bio-based flocculants have received a lot of attention due to their superior advantages over conventional synthetic polymers or inorganic agents.

Which flocculant is used to treat kaolin suspension with polyaluminum chloride?

For example, a cellulose-based flocculant C-g-PDMC (Li et al. 2018), which was prepared by methyl acryloyl oxygen ethyl trimethyl ammonium chloride grafted to microcrystalline cellulose, was used to treat kaolin suspension with polyaluminum chloride (PAC).

What is a copolymer based flocculant?

Copolymer has been obtained by ultrasonic initiated grafting of CS by acrylamide and 3-acrylamide propyltrimethylammonium chloride. This new type of flocculant has been used in combination with kaolin to enhance the flocculation efficiency.

What is a flocculant used for?

Previously, mainly inorganic compounds (such as aluminum sulfate and iron chloride) were used for water and wastewater treatment, owing to their high availability and low price, but currently polymers (both synthetic and natural) are increasingly popular flocculants.
