Аннотация:Dependence of quantity of suspended substances and working pressure on selectivity and permeability was studied for membrane m wastewater treatment process in sulphate cellulose production. Research was earned with use of different polymer membranes - acetatecellulose, composite and others and ceramic and carbon inorganic membranes.Suspended solids m wastewater lowers permeability in 1.44-1.65 times in comparison of permeability for distilled water.Concentration of suspended substances 150-200 mg/l was determined as critical concentration, at higher concentrations sediment of suspended substance gets mam affection on permeability.Different wastewaters of sulphate pulp production can be treated at inorganic membrane devices without settling or pre-filtering if concentration за suspended substances is guaranteed lower than 30-50 mg/l.
