SWP compact screen unit

• Automatic running such that constant supervision is not required
• Cyclic action, minimal wear and tear
• Quick and easy assembly
• High efficiency with low operation costs

 Compact screen unit SWP consist of:
        - Screenings Press PRE
        - Spiral Feeder PSE

    Separation of solids found in municipal and industrial wastes is a major problem for sewage control systems. These solids are usually hygienic product wastes, plastic parts, rags, corks, kitchen wastes, etc. Separation of these solids prevents blockage of fittings and mains. It also allows technological processes to operate without disturbances. For solid separation we offer you a modern and proved device- a SWP screen with Rakings press.

Performs a Number of Functions
- Mechanical waste separation (screenings),
- Transport of screenings,
- Dewatering (up to 60% of original volume), compacting and pressing of screenings,
- Prevents blockages in sewage collection systems.

Advantages
- Automatic running such that constant supervision is not required,
- Cyclic action, minimal wear and tear,
- Quick and easy assembly,
- High efficiency with low operation costs.

Description and Principles of Operation
After connecting the cesspool emptier hoses to the screen and after opening the pneumatic ZEN valve of the decanting device, gravitational sewage release occurs. Solid wastes flowing in the sewage settle on the filtering screen. Screw scraper removes the screenings from the screen and transports them up. Dewatered screenings fall into the charging hopper of the screening press. The press collects the material from the hopper into the pressing chamber, where the pressing of the screenings occurs. Pressed screenings are then subjected to additional compacting inside a specially shaped ejector pipe, through which they are expelled into attached plastic bags or other containers.

SWP Compact Screen Unit is a modern device satisfying all ecological requirements. It can be fitted either as an additional device (pre-cleaning the sewage) in front of the STZ decanting device or it can collaborate with other devices of the sewage treatment plant.

Screening press PRE

• The screenings press PRE is a device designed to dehydrate and compact solid wastes (bottles, rugs, bottle tops, stones, plastic parts, etc) transported by screenings sieve.
• The press can be used as an auxiliary device for the sieve as well as for other devices used in wastewater treatment plant (or sewerage collection points).

Operation Principle
Screenings are passed by means of spiral conveyor or belt conveyor from the sieve to conical in shape dumping basket of the press. From there the screenings are transferred to pressing chamber. Compacted screenings are pressed even further in especially shaped ejector pipe. The ejector pipe removes the screenings compacted this way to plastic bags.

PSE spiral feeder

Description and Principles of Operation
The spiral feeder consists of a working tray with a plastic lining, and a worm located inside the tray. There is a charging hopper in front of the feeding screw.
Screenings are dropped to the charging hopper, from which they are moved to the distance determined by the throw opening. They are usually being dropped into the containers located below. The spiral feeder can operate in a horizontal or angular (0-30°)position. It also has optional radial rotation of the transporter depending on the requirements of the dumping place.
