Nowadays the amount of poisonous substances in running water in the network of household-
communal industrial factories. As a consequence, it is causing some problems.
One of the main reasons of it is that residential places and industrial factories are not
properly equipped with canalization network and construction to purify running water. As a
result, there are some substances which are harmful for living organisms such as different acids,
phenols, hydrogen sulfate, ammonia, brass, zinc, lead oil, petroleum in the structure of the
running water, and they pollute not only water in industrial factories but also rivers,lakes,
reservoirs and channels. As water resources get polluted with running water, it brings huge
damage to national economy. Besides that, polluted water in these resources are defined to be
worthless to irrigate communal-household, industrial water supply.
Even though there are several actions taken to preserve nature in the territory of the
Republic of Uzbekistan, decreasing pollution of external environment and building the
constructions to increase the productivity of running water purification is considered to be
conventional issue of today. So, decontaminating running water from waste plays a big role in
national economy and social life. Mechanical, biological and physicochemical methods are
used to purify running water. Level of purification, conducting capacity, methods to treat
alluvion, structure of running water, local conditions and economical indices are taken into
consideration when choosing purification methods and constructions.
There are 43 manufacturing factories in Andijan city, 12 of them do not have structures
to cleanse running water. Moreover, 9 of them have low indices of using water constructions
and purifying water and they are divided into the following classes:
Biological class includes microorganisms, fungi, bacteria, mild seaweeds and viruses.
Bacteriological class includes microorganisms which lift and spread infectious diseases. There
can be pathogenebacteriums such as typhus, paratyphoid, dysentery, Siberian ulcer, helmint in
running water.
Polluting substances can be in big dispersed form( measure of particles is 0.1 mkm… to
0.1 mm), in the form of suspension, foam and emulsion(0.1 mkm…to 0.1mm) , in the form of
colloid( 0.1 .. to 0.001 mkm) and in molten form.
Nowadays, chlorine is widely used to neutralize running water.
Chlorination method id done with the help of special device.
Counted portion of chlorine for mechanically purified water is 10mg
Mixing of running water into flowing water basins(river, channel) is defined with the
coefficient which is determined by method of V.A.Frolov and R.I.Rodziller(3)
