Abstract
It is shown the current ways of water treatment which are recommended by Classifyer of ground water purification and their disadavnatages with considerable operational cost. The common disadvantage of these installations is high energy consumption for production of one unit of distillate. The article presents an energy efficient solution of existing problem of water dessalination with low power consumption in combined water treatment device. The received results of experimental research of reverse distillate quality indicators after water treatment installation are to prove it’s operationability and effectiveness for small power engineering and systems of heat supply. The complex shows an energy consumption decrease, allows to engineers exclude the use of chemical reagents, the volumes of waste waters, to reduce considerably consumption of rinse water for own needs and cost of dessalination and purification of water, as well as cost on its warming. The article analyzes the current situation in technogenic zone of Aral Sea region.
