Production of drinking water from small-scale water reservoirs

Summary

Production of drinking water for domestic use from small-scale water reservoirs with limited yield and initial water quality formed under natural and anthropogenic impact is of special interest. The methods of water pretreatment (chemical free removal of phytoplankton in prefilter with floating medium and oxidant integrated effect) are considered; their contribution to the improvement of water coagulation process has been experimentally proved. The method of calculating coagulant dosage with the use of the coagulation capacity complex factor that takes into account inter alia the effect of zeta potential is suggested. Advanced technologies of water treatment are considered; the results of their industrial-scale testing are presented.

Key words

phytoplankton , primary filter , small-scale water reservoir , water pretreatment , oxidant , coagulant dosage , coagulation capacity complex factor , zeta potential
