  • It is also possible to make the pieces in all required lengths.
Application:
  • Produced fittings are mostly installed on pumping/lifting pumping stations in both cases, for drinkable or waste water, water reservoirs and similar.
Material:
  • Fittings are made of stainless steel or carbon steel with subsequent anticorrosive epoxy protection or other coating or galvanization.

2 Fittings in water supply and drainage - orbital

Fittings in water supply and drainage - orbital
Design:
  • Orbital welding is a process in which an electric arc travels around the workpiece in a circular motion, where the arc travels at least 360 degrees around the workpiece without interruption. The application of orbital welding depends on the thickness and type of material, accessibility of the weld joint, preparation capabilities, etc. Orbital welding can be used to weld circular elements such as pipes, bends, elbows, T-pieces, flanges, various pipe fittings, and similar connections.
  • Standardly produced custom pieces include: F, FF, FFK, FFR, Q, T, flanges (for all diameters and pressures). All other non-standard pieces can be produced according to project requirements.
  • Additionally, it is possible to manufacture pieces in all required lengths.
Application:
  • Custom pieces are mainly installed in pump/lift stations, whether it's for drinking or wastewater, water reservoirs, etc.
  • Orbital welding provides the ability to weld in all welding positions, and welding can be performed on-site.
  • Orbital welding can be used to weld pipe-to-pipe joints with the following dimensions: DN50, DN65, DN80, and DN100, wall thickness ≥3.0 mm, made of stainless steel, titanium, and structural steel.
  • Flat flanges cannot be welded using orbital welding; instead, loose flanges EN 1092-1/type 02 are used, where the flange is orbital welded to the pipe, etc. For pipes with dimensions DN50, DN65, DN80, flange EN1092-1/type37 with wall thickness ≥ 3.0 mm is used. For pipes with dimensions DN100, flange DIN 2642 with wall thickness d ≥ 3.0 mm is used.

3 Sludge thickening and dewatering unit

EKOsludge PRESS1

Sludge thickening and dewatering unit
Screw press main characteristics:
Q SCREW PRESS CAPACITY 3-600 kg–DS/h depending on selected type
LxWxH RESS DIMENSIONS 2,1x1x1,2m up to 5,5x2,7x2,4m
Application:
  • Unit is used for the purposes of sludge thickening and dewatering in either municipal waste water treatment plants, or in industrial plants.
  • Due to the specific construction, sludge thickening and dewatering unit can treat sludge directly from the biological tanks or from secondary settling tanks (DS content of 0.2-5%) without the need for construction of a separate thickener
Short description:
  • Sludge thickening and dewatering unit is manufactured as a pre-mounted plant which among other consist of multi plate screw press, sludge feed pump, automatic polymer preparation unit, dosing pump, electric control cabinet and, if necessary, sludge transportation and hygienisation system.
  • The central part of the sludge thickening and dewatering unit is multi plate screw presses as shown in the figure below.
Operation principle:
  • Sludge is transported to the multi-plate screw press by means of a sludge feed pump. At the same time, from polymer preparation unit dosing pump is transporting prepared polymer solution into the press.
  • After treatment in the preparation tank, sludge travels through the press to discharge of sludge cake under the influence of force that the device produces.
  • While the gap between the helical axis blades gradually gets narrower and narrower, the sludge is under heavier and heavier pressure. The water gradually comes out form the sludge as a result of differential pressure via the filtering gap between the fixed plates and the moving plates.
  • Due to a self cleaning function of the fixed plates and the moving plates, the clogging problem is avoided.
  • The sludge is pushed by helical axis after being fully dewatered and then discharged to the outlet.

4 Wet single-stage chemical filter

EKOvent APOX1

Wet single-stage chemical filter
Basic sizes:
  • The dimensions of parts of this device are derived from the constructional dimensions of the spaces from which it is necessary to purify waste air, i.e., based on the required air flow rate.
Application:
  • These devices are installed in places where it is necessary to purify polluted air resulting from technological processes.
Design:
  • The wet chemical filter is standardly made in a vertical design from stainless steel and is suitable for both indoor and outdoor installation.
Operating principle:
  • The amount of solution in the wet filter is maintained via a level regulator. Gas treatment (washing) is carried out on the surface of special polypropylene filling. The fillings are washed via nozzles and a high-pressure pump, all with the help of a solution whose pH value is constantly measured and automatically adjusted as needed. Periodic discharge of the resulting sediment is done via a manual or automatic valve. The amount of sediment depends on the load and the filter's operating mode. The filter is equipped with all necessary equipment for 24-hour operation.
  • The filter is controlled via an electrical control cabinet. An additional tank for process chemical (alkali or acid, depending on the type of flushed gases) and automation for controlling the solution's pH value and dosing of process chemical are supplied with the filter. The filter must be connected to the water supply network and wastewater system. The fan is installed inside the filter at the top.

5 Wet two-stage chemical filter

EKOvent APOX2

Wet two-stage chemical filter
Basic sizes:
  • The dimensions of parts of this device are determined by the constructional dimensions of the spaces from which it is necessary to purify waste air, i.e., based on the required airflow rate.
Application:
  • These devices are installed in places where it is necessary to purify polluted air resulting from technological processes.
Design:
  • The wet chemical filter is standardly made in a vertical design from stainless steel and is suitable for both indoor and outdoor installation.
Operating principle:
  • The filter is two-stage, consisting of two reactors.
  • The polluted air first enters the acidic reactor, where nitrogenous alkaline compounds are removed. The second reactor is alkaline, where acidic sulfur compounds are removed.
  • The polluted air is washed in softened water to which appropriate alkaline or acidic chemicals are dosed.
  • The amount of solution in the wet filter is maintained via a level regulator. Gas treatment (washing) is carried out on the surface of special polypropylene filling. The fillings are washed via nozzles and a high-pressure pump, all with the help of a solution whose pH value is constantly measured and automatically adjusted as needed. Periodic discharge of the resulting sediment is done via a manual or automatic valve. The amount of sediment depends on the load and the filter's operating mode. The filter is equipped with all necessary equipment for 24-hour operation.
