The technology of reverse osmosis concentrate disposal in water treatment systems

Summary

The use of membrane reverse osmosis units in drinking water treatment is complicated by the presence of the concentrate waste streams that are to be disposed. The technology of removing (crystallization) calcium carbonate contained in the concentrate on crystal seeds is suggested and experimentally tested. From natural water the reverse osmosis units can produce deep-desalinated (softened) water and water with lowered concentration of calcium and bicarbonate ions with total dissolved solids concentration similar to that in raw water. The developed technology can be efficiently used in drinking water treatment as well as in integrated boiler and heating network makeup water preparation.

Advanced technologies and equipment for magnetic water treatment (review)

Summary

A review of perspective advanced trends and approaches in the practical introduction of scale-control magnetic water treatment in heat power engineering and related industries including water purification to remove hardness salts scale formation (carbonate, chloride, and sulfate salts of Ca²⁺, Mg²⁺, Fe²⁺ и Fe³⁺) in heat-exchange facilities, pipelines and plumbing units is presented. The principles of physical impact of magnet field on water, parameters of proceeding physical and chemical processes and behavior of hardness salts dissolved in water are considered. It is shown that the magnet field effect on water is integrated and multifactorial. The design features of home industrial-scale magnetic water treatment devices with permanent and electric magnets – hydromagnetic systems, magnetic converters and magnetic water activators are presented. The efficiency of using water magnetic treatment units for water purification is considered.

The specific features of introducing the principle of best available technologies in municipal wastewater treatment

Summary

The aspects of implementing the principle of best available technologies in municipal wastewater treatment are considered. The analysis of the techniques of determining the permissible concentrations of pollutants discharged into the water bodies is presented. The classification of typical technologies of municipal wastewater treatment is given. Based on the summary data on the best available technologies the levels of basic pollutants removal from municipal wastewater are presented. The priority of introducing process-oriented regulatory actions for public utilities in 2012 is pointed out. The quality parameters of effluents discharged into the water bodies with account of their condition are suggested as technically achievable and sufficient for being observed environmental standards.
