Reducing residual aluminium concentration in drinking water at the Yaroslavl South water treatment plant

Summary

The aspects of elevated residual aluminium concentrations in drinking water at the Yaroslavl South water treatment plant are considered. On the basis of analyzing the data on water quality the effect of separate parameters on the residual concentration of aluminium was revealed. The experimental results of investigating the Volga river water treatment with the use of different coagulants and flocculants are presented. The expediency of replacing aluminium sulfate and Praestol-650 flocculant with aluminium oxychloride coagulant in cold seasons is shown.

The current state and problems of the public water supply system of the city of Irkutsk and Irkutsk Area

Summary

Supplying the population with high quality drinking water has been a high-priority task of the urban land development. Lake Baikal and the Angara River, its effluent, supply most of the Irkutsk Area population with drinking water. The pure drinkable water of Baikal that the Angara is carrying is as such only upstream of Irkutsk. Onwards it turns into the holding pond of industrial and domestic wastewater. Downstream Irkutsk the Angara water cannot be used for drinking water supply without organics, heavy metals and oil products removal. Using the example of establi­shing the public water supply system of the Irkutsk Area the aspects of supplying water from the open surface water sources were studied. It is shown that the water use under the conditions of the regulated surface water sources with significant water level fluctuations demands constructing combined water intakes of special design – shore, channel, infiltration and pontoon. The sources with low-mineralized water shall be used in combination with mineralized underground water. The need of developing group water supply systems with the use of protected underground water sources or large-scale surface fresh water sources is shown.

Technology of high-speed water clarification with the use of microsand

Summary

The Research & Development Centre of MPUE Mosvodokanal investigated a new process of high-speed water clarification. The presented technology is an upgraded option of the traditional technology of water clarification. It allows using the potential of coagulation-settlement processes to the maximum extent. These processes have been the vital stage of the water treatment technology. The results of the studies showed that the developed technology ensures more efficient color and permanganate oxidizability removal compared to the traditional water treatment process used; besides, it decreases drastically the concentration of residual aluminium in drinking water.
