BIOSORPTION METHOD FOR WATER TREATMENT FROM CADMIUM

摘要

A biosorption method for water treatment from cadmium consists in complex treatment of water from cadmium. On pretreatment stage adsorption of cadmium is carried out on mixture of clay with chitosan (in equal quantities). On advanced treatment stage the adsorption of composition on biofilters is carried out, which are preliminary immobilized association of nonpathogenic bacteria strain of Pseudomonas genus at temperature of 30° C and value of pH 7, and it is allowed achievement of cadmium concentration less than MPC.
