This kind of screens can be used for many applications: pumping and filtering stations (irrigation, flood control, rain sewerage network), municipal treatment plant, drinking water plants, water intakes (cooling water for hydro power plants and refineries), industrial water processes and wastewater treatment plants.
AQUARAKE DIM with stainless steel gears and high resistance bearings
ADVANTAGES
- For channels wider than 1 metre
- Mechanical assembled curved bars for better waste collection at the bottom of the screen
- Continuous self cleaning of the grid
- Screening mesh from 6 to 50 mm
- Flowrate up to 11,000 m³/h
- Option: sloted grid or perforated plate for bar spacing from 1 to 5 mm
The AQUARAKE DIM is an inclined continuous bar screen. A set of scrapers attached to two side chains is driven by two sprockets located at the top of the equipment, which are themselves driven by a single gear motor. The chains are turned by sprockets located at the bottom.
The automatic screen starts and stops according to upstream effluent level (level sensor) or by clock timer.
The waste trapped against the bars is caught by the multiple rake’s teeth and lifted up to the discharge point. A back plate prevents the debris of falling back into the wastewater down the grid.
The scrapers then transport the screenings to the ejector, with a rear plate preventing them from falling back down during the ascent. The ejector directs the screenings from each scraper to a container, a conveyor/compacting screw or a washing compactor.
Finally, the cleaned scrapers return to the bottom to begin a new cycle.
