Description:
The study characterized the post biological solids in pulp and paper mill secondary effluent and evaluated various suspended solids removal techniques. Characterization was performed on samples from 9 mills, representing various locations, pulping processes and treatment system types. Results indicate the solids are mostly biological in nature. Coagulation by alum in conjunction with a cationic polymer appeared to provide the best results. Six solids removal techniques were tested but only mixed media filtration and sand filtration appeared effective enough to warrant further investigation.
