Application

The horizontal sludge scraper is a solution for condensing and removing bottom sludge. The device is used either in water or sewage and industrial wastewater treatment stations. Scraper of unique triangular concave shaped ensure efficient sludge movement in following sedimentation tanks: post-coagulation, preliminary, secondary, as well as desludgers and horizontal sand traps.

Functioning
The movement of sludge collected on the bottom is performed with two evenly assembled scraping parts. They cover the whole chamber bottom in a form of bobbing motion frame which slows down extremely when approaching the contamination release point – 0,1/1,0 m/min, and turning motion is performed three times quicker. Thanks to the unique scrapers shape the sludge is delicately moved towards the release point with a concave parts of them, and the sludge is carried over the scrapers in turning phase thanks to the triangular shape of the board. The innovative structure ensures continuous, constant and undisturbed transporting the sludge towards the release point built of the sedimentation hopper. The additional advantage caused by the above solution is a small whirl created within the sweeper which additionally condenses the sludge. The device may be additionally equipped with bottom measurement and automatic sludge release systems.
