STUDY OF KINETIC COEFFICIENTS OF WEAKLY MINERALIZED REVERSE OSMOSIS SEPARATION SOLUTIONS SEWAGE

Annotation

The paper considers the possibility of using reverse osmosis separation solutions in wastewater treatment from heavy metal salts. To study the influence of the parameters of the process of separation of basic kinetic characteristics of experimental studies and permeability coefficient detention membranes MGA-95 MGA-100 wastewater treatment of salts of heavy metals: Zn, Cd, Pl. The regularities of changes in the coefficient of permeability and retention depending on the pressure and type of membrane for all test solutions are disclosed. It is explained how the main parameters of the kinetic characteristics of the separation process.

Keywords

rejection coefficient; membrane; reverse osmosis; separating process; water penetration capacity; apparatus.
