Cleaning processes play a major role
in the maintenance of municipal
systems. The objects to be cleaned
include sewer channels, pipelines,
wells, shafts, settling basins and civil
engineering constructions.
Since more than 40 years, WOMA's
high-pressure water jet technology is
successfully used in these areas for
the following applications:
|
 |
Removal of incrustations and impurities from pipelines. |
|
Cleaning of sewers and collecting drains of different profiles and wall materials. |
|
Removal of drain skins from sewer walls. |
|
Removal of impurities and foulings in settling and aeration basins. |
|
Cleaning of drainage pipes in drinking water wells. |
|
Scouring of deep wells. |
|
Cleaning of sewer- and sludge troughs and sand catchers. |
|
Removal of impurities from drainage filter presses. |
|
Cleaning of garbage chutes. |
|
Cleaning of concrete, stone and brick surfaces. |
|
Surface preparation of steel and concrete structures. |
|
Cleaning, paint removal and roughening of traffic areas. |
Why High-Pressure Water Jets? |
|
Very wide range of application in all areas of the municipal technique. |
|
Wide range of tools and accessories. |
|
High cleaning efficiency even in areas of difficult access. |
|
Possibility of mechanization of cleaning tools. |
|
Disburdening of operators from manual, dirty and insanitary jobs. |
|
Avoidance of any gas and slag. |
|
Avoidance of chemical or abrasive additives. |
|
Very sensitive and selective removal of coatings, impurities and deposits without damaging the wall materials. |
|
Possibility of combining cleaning and suction. |
|
Applications possible during active production. |
The Material Range |
|
Using high-pressure water jets,
among others, the following materials
can reliably be removed:
Bacterial
cultures, coatings, deposits, filtrates,
incrustations, organic foulings, oxide
layers, paint systems, sludges.

The Technique |
|
WOMA offers stationary and mobile
high- and ultra-high pressure water
jetting systems with operating pressures
up to 3,000 bar and water flow rates
up to 1679 l/min, consisting of electric
or combustion drive, high-pressure
plunger pump, guiding and control
devices, water tools, and high-pressure
accessory. Also, for operating pressures
up to 400 bar, abrasive resistant pumps
(ARP®) are available for dealing with
impurified water.
Moreover, WOMA
offers hot waterjetting systems with
operating pressures up to 800 bar
and mobile compact systems with
operating pressures up to 1,000 bar.
The special high-pressure program for
municipal applications also includes
the following components:
|
|
Vertical high-pressure plunger pumps for the installation in municipal vehicles. |
|
High-pressure guns in modular design for cleaning, decoating and selective material removal. |
|
Whirl jet nozzles with several orifices for cleaning partially or completely blocked tubes. |
|
