Mechanical Engineering Equipment  -  Longitudinal & Circular Scrapers

Sand trap scraper

UWA longitudinal scrapers can be installed in all rectangular basins which are constructed pursuant to din 19 551.
Depending on requirements, the facilities can be provided with track or trackless operation, with or without a rack and pinion drive.
The high standard of the UWA technology guarantees an absolute synchronism and a safe winter operation.

The high degree of automation, e.g. resulting from a height-adjustable sand and floating matter shield guarantees an optimal scraping. The plate design which is of seawater-resistant aluminium or stainless steel, provides the highest level of corrosion protection and guarantees a maximum serviceable life of the plant.

The individual components meet the high requirements of DIN 19569, especially with regard to the load and material requirements which are to be taken into account. The travelling speeds are also designed in accordance with DIN. The running gears are so designed that they withstand the highest load, have the lowest maintenance requirements and guarantee a trouble-free operation.

 

Longitudinal scraper

UWA has accepted the challenge to provide technology form the mechanical treatment of sewage which is to be permanently improved. In accordance with DIN 19551, Part 3, scraping facilities designed for the most diverse tasks and developed further development so that they are always of the latest state of the art. The tend-setting style is ideally suitable for tailor-made problem solutions. All of the UWA scrapers can be fitted with automatic floating matter and floor scraping shield.

The highest level of economic viability thanks to a perfected solid technology and the resulting minimum in maintenance expenditure, are the most distinctive features of the UWA plants. UWA offers an automatic spraying system with mobile spraying arms and a pump (model LW) for use in rain basins. The UWA specialists provide advice on the possibility of installing components which can be put to a customised use.

The scrapers in the form of a plate bridge are available in aluminium, stainless steel or galvanized steel.
UWA provides band type scrapers in all required designs for use in rectangular preliminary and subsequent settling basins, especially with chains and plastic scraper beams. Components which are subjected to high loads are made of stainless steel.

Round scraper

UWA supplies scraper devices in the form of sludge scrapers with a decentral RS pumping station or a suction scraper with a RS pumping station integrated on the bridge, whereby the round subsequent settling basis with a horizontal bottom is without a doubt the most economical solution for suction scrapers.
As a result of the year-long experience in the development and production of round scrapers and a permanent innovation, UWA is able to supply mechanical engineering technology with decisive advantages:

- optimal degree of separation
- immediate sludge recirculation
- high oxygen content of the RS
- no sludge buoyancy

As with all UWA plants, a solid processing down to the smallest detail is guaranteed with regard to the scrapers. UWA permanently conducts its own quality control inspections during production. The scraper bridge comprises a robust plate design in hot-dip galvanized steel, aluminium or even completely in stainless steel, including safety gratings. The drive is guaranteed by a running gear which is screwed onto the scraper and a high-performance back-geared motor. Operating disturbances caused by obstacles on the bearing surface of the basin wall is avoided by the stripping edges. The electrical equipment of all UWA plants are of the latest state of the art and is always in the IP 55 system of protection. A weatherproof switch cabinet with well arranged operating elements is situated on the scraper bridge.

Perfected technology
