COMPLEX LOW-WASTE TECHNOLOGIES FOR WATER
PURIFICATION FROM IRON COMPOUNDS
Introduction. Due to the prolonged increase of anthropogenic activities,
pollution occurs. Some regions of our planet are suffering from a catastrophic shortage
of water, besides facing another problem - the poor quality of water resources. Heavy
metals are the most dangerous [1]. High pollution of water objects with mineralized
waters and toxic substances requires the development of effective measures to reduce
this impact.
The problem of domestic and drinking water consumption and the protection of
surface and groundwater from pollution by sewage and shale waters is a problem of
state importance. In Ukraine, widespread work is carried out on the obtaining of iron
ore by open and closed methods, in which a large number of quarry waters
contaminated with iron compounds, petroleum products, sulphates, chlorides,
suspended solids and other substances are formed. A method of purification of highly
mineralized waters from sulfates with simultaneous mitigation is considered in [2, 3].
Before discharging in surface water, industrial waters must be purified from pollutants,
primarily of iron [4].
In Ukraine, more than 50% of the operational stocks of groundwater have an
increased iron ions content, which varies from 0.5 to 30 mg/dm
3
or more (mostly 3-
5 mg/dm
3
). Excessive amounts of iron ions provide a metallic flavor to the water, cause
an unpleasant smell, turbidity, water color, overgrowth of water supply networks and
cause shortages in the paper, textile, food, chemical and other industries. In addition,
