Nonchemical underground water treatment
(Case study of the Amur water intake, the city of Komsomolsk-on-Amur)

Summary

Until the present no economically available and environmentally substantiated process scheme of a land-based underground water conditioning plant in the Far East has existed. High concentrations of iron and manganese at low Eh and pH values predetermined the use of chemical methods of treatment. The comparison of two process flow schemes – chemical and nonchemical (with the use of catalytic filtering media) is presented. It is shown that the use of the technology with three chemicals is not the only possible solution. The use of imported equipment and chemicals makes the operator of the municipal water treatment plant dependent on the pricing policy of the supplier. A process flow scheme of water treatment tested under the real-time conditions of a water intake and approved for the introduction with the use of catalytic filtering media and Russian-made equipment is presented. The main task in developing the process flow scheme of nonchemical water treatment was enhancement of the treatment processes with the aim of reducing capital and operational expenses.
