The mining and metallurgical industries are two of the major water consumers:
-
iron and steel works
-
coking plants
-
minimetallurgical plants
-
foundries
-
ferroalloy plants
-
ore concentrating plants
Facilities requiring water treatment include:
-
power generating equipment (hot-water and steam boilers), heat and power station
-
process water supply including water intake
-
cooling circuits
-
drinking water supply
-
waste water
The water facilities of iron and steel plants are interconnected with municipal services because they have common a water supply, common heating and domestic waste water channels.
Requisite services include:
|
|
water treatment (sea water desalination, partial and deep desalination) for power generating equipment (feed water preparation for steam and hot-water boilers, waste heat recovery boilers), the greater part of manufacturing equipment of galvanic, plate rolling and tube-rolling processes;
|
|
|
filtration and cleaning of recycled water
|
|
|
feed water preparation
|
|
|
development of water treatment systems of the various production and enterprises (incl. zero-discharge WTP)
|
|
|
stabilization water treatment with chemical and nonchemical methods to prevent sedimentation and corrosion formation; adjustment of reliable water chemistry of the cooling systems, heat supply system and boiler equipment
|
|
|
waste water treatment of oil emulsion, saline, SAW- and chromiferous water; full elimination of the liquid discharge; reduction of the source water consumption.
|
Depending on the desired quality and requirements of the water, the company can apply modern and conventional water treatment technologies:
-
Chemical Treatment (coagulation, flocculation, soda liming)
-
Filtration on sediment, screen, cartridge and bag filters
-
Ultrafiltration
-
Reverse Osmosis and Nanofiltration
-
Electrodeionization
-
Ion-Exchange technology
-
Membrane Degassing
-
Treatment in the field of gravitational forces (sludging, centrifuga, slurry decantation)
Reconstruction and audits are carried out for existing water industry objects. Basic principles of decision making are: power efficiency, adoption of new efficient technologies, minimal ecological impact (Kyoto Protocol adherence).
