Method of removing color from waste water using an aqueous dispersion polymer |
摘要 |
A method for removing color from a paper mill waste effluent which comprises the step of adding a low molecular weight hydrophobic polymer dispersion to the effluent. The hydrophobic dispersion is preferably formed from the precipitation polymerization of at least one hydrophilic monomer and a hydrophobic monomer in the presence of a precipitation aid, water, a chain transfer agent, and an initiator.
