The Use of Nanofiltration Membrane OPMN-K for Production of Potable Water and Calculation of Operation Characteristics

Summary

Recommendation on the use of nanofiltration membranes OPMN-K manufactured by the Vladipor OJSC for natural water treatment and production of potable water of high quality are presented. It is shown that at the high efficiency of removal of iron, hardness, fluorine and ammonium ions from water the OPMN membranes are exposed considerably less to the danger of generation of calcium carbonate cake on them than the low pressure reverse osmosis membranes. Depending on quality of influent water and types of membranes these recommendations make it possible to determine the reagent consumptions for operation of plants. Calculations presented show that the use of OPMN-K membranes instead of reverse osmosis membranes ESPA makes it possible to reduce significantly expenditures for operation of the ground water treatment unit.

Key words

nanofiltration membrane , inhibitor , selectivity , operation expenditures , reverse osmosis unit
