SEWERCLEANING
The clogging of sewer networks, partial or full, is
pretty unpleasant inconvenience as it is slowing
the drainage of water. The clogged sewerage is a
prerequisite for inundations and corrosion of the
pipeline, as well as for the intermittent water
pressure in the pipes, leading to your premises.
The clogged sewerage almost always causes an
unpleasant odor and deteriorating hygienic
conditions. These conditions are favorable environment for breeding of rodents and disease-causing
organisms.
The reasons for clogging the sewer might be different - the fallen trashes, dirt, construction garbage
and insoluble bodies, accumulated sludge or deposits over the operation, and also reverse or
insufficient slope of the pipes inthe installation. Thus on the walls of sewer pipe are forming fat
deposits, aggregates are pelleted at the bottom of the sewer, with the consequence of that, its cross
section is reduced, the drag which the sewer has on the water is getting worse and hence its
permeability.
The drainpipes that are responsible for the distribution of the waste water are arranged in such a
way that their pollution is almost inevitable and at some point comes the clogging.Maintaining all
sewer systems in proper condition is an important aspect and gives security and comfort. In case of
pollution of a sewer section, its replacement is not the most appropriate solution as the new pipes
will soon begin to accumulate deposits just as the previous ones.
The cleaning and unclogging the sewerage is performed by the following methods: mechanical,
hydrodynamic, thermal and chemical. The use of any of methods is important in a special situation.
Mechanical cleaning of the pipes means that the removal of
the dirt is performed with a steel cable and a metal tip, or
fitting. Mechanical cleaning is performed, in cases when
the pipe is with diameter of 30 mm to 200 mm, i.e. for
smaller sizes. This method is most acceptable for
unclogging sewers on removal of roots, rags, grease and
accumulation of deposits in the pipes. It uses "riders",
mechanical equipment, which scrape or cut the blockages
in sewerage.
The hydrodynamic cleaning is also an effective way, and is
used in unclogging of varying complexity. The essence of
-
SEWERCLEANING this method consists in washing the pipes with water under high pressure of about 150-300
atmospheres. This cleaning method can be applied in almost all cases, as it does not violate the
complex of pipe connections.
The hydrodynamic method involves
the use of hoses for suction sewerage
under high pressure - the so-called
water hoses "jets". The water stream is
sprayed on the sewerage and removes
the accumulated silt, mud and
fragments, spraying and releasing
them, as a result they are washed.
The process consists of two
components, the first component is
pumping water under high pressure,
and the second component is a
vacuum suction of the transported materials from the sewage pipe. Both processes are performed
synchronously and continuously. As already mentioned some of the equipment of the machines for
unclogging the sewerage, which should keep the level of quality of the work, are the hoses for
unclogging the sewages and the hoses for ejection of the waste materials.
The main criteria for high quality cleaning are:
maximum working pressure;
length;
safety when assembling the hoses
reliability of assemblies;
pumping capacity;
used nozzle.
Using trucks for unclogging sewerage, equipped with water"jets" are also required for removal of
roots that need to be cut off or removed from the clogged sewer. The water "jets" for sewerage are
long, flexible hoses for high pressure with nozzle at the one end, the other end is hooked to sprayer
or compressor pump of the truck for unclogging the sewerage. In most cases, the nozzle of the hose
for unclogging sewage is front-injection.
The hoses for unclogging sewerage must be resistant to high pressures and resistant to the
conditions and chemicals, which might be collected in the sewerage.

Method for chemical cleaning is usually used to dissolve and soften the nature of the organic waste
by reactive materials and reagents. This method can be used to maintainthe operating conditions of
the pipe and to prevent clogging.
