Program for Technological Calculation of Nanofiltration Systems
The program of technological calculation of nanofiltration systems for potable and technical water supply has been developed on the basis of experimental works with the use of membranes produced by Saehan Co., South Korea. The program makes it possible to analyze the composition of water treated and to recommend optimal operation conditions in order to reach the preset water quality at minimal operating cost.
Key words: membranes, nanofiltration, ion concentration, pollution, inhibitors, reverse osmosis, potable water.

Improvement of Efficiency of Water Treatment at Filter Plant
The results of laboratory research in intensification of coagulation of the Vychegda and Staritsa Rivers water, the sources of water supply of Solvychegodsk railway station, are presented. On the basis of tests carried out it has been proved that in order to obtain potable water of standard quality the joint use of aluminium polyoxichloride coagulant and flocculant Praestol-650 TR is the most efficient method.
Key words: water treatment, turbidity, chromaticity, alkalinity, odor, iron concentration, coagulant, flocculant.

Removal of Humus Compounds from Water in Electric Discharge Reactor
The results of research in removal of humus substances from water solutions and water in an electrical discharge reactor with steel granules are presented. A mechanism of humus substances removal consisting of partial oxidation, coagulation on iron hydroxides and cementation of electroerosion products of granules has been determined. It is proved that the efficiency of treatment for humus substances increases with the rise in pH. This method makes it possible to reduce energy expenditure by 3-3,5 times as compared with electrocoagulator with aluminium soluble electrodes.
Key words: humus substances, electric discharge reactor, steel granules, water treatment.
