Dutco Tennant LLC can take care of all your wastewater and sewage treatment solutions. Our supplied scrapers for wastewater treatment are manufactured as per a moderate design which is mostly comprised of stainless steel. The supplied rotating sludge scrapers of semi-bridge and full-bridge are mainly of latticework type. They can be found in a varied range of configurations such as with supplementary functions or without. The main types of scrapers are semi-bridge scrapers, peripheral driven full-bridge scrapers, or central driven.
Either peripheral or central drive is utilized by sludge scrapers for circular tanks. This mainly depends on the diameter of the tank, process, sludge loads, and design. Via various classifications, the circular scrapers can be studied. As peripheral driven rotating bridge scrapers and central driven fixed bridge scrapers, they can be classified without any regard to their drive. To the diameters of the basin or any fraction of the basin diameter, the rotating bridge scraper’s length can be equal. The method of disposal of sludge is determined by the solid load of the wastewater treatment system . The accumulated sludge at the bottom can be either pumped to the central structure’s pipeline by the pipes for suction or scraped into the funnel of the sludge. For both methods, various options can be brought out.
Our supplying partners have standardized their manufacturing models for using efficient modern methods for guaranteeing products of high-quality as expected by our clients. The design has been done in an efficient way so that the wastewater treatment scrapers can last for almost 40 years. High loads of sludge can be handled by rigid, strong, and torsion-resistant bridges. The quality of steel underwater is mostly AISI304 stainless steel. Our supplied range of bearings and motored gears are all coated as per the requirements of the customers. The driveshafts made up of carbon steel are treated for anti-corrosion as they are not made up of stainless. We supply wastewater treatment scrapers of semi-bridge and full-bridge design having latticework design type having tubular vertical supports that are bolted or welded onto horizontal beams which are supported from the bridge. For bottom scraping, there are angled scraper blades present to remove the sludge from the entire floor to the pit of the sludge at the tank’s center. The units are having surface sludge blades like other options that can transport floating sludge into a sludge cone. Below the rotating bridge, the floating wastewater treatment scraper blades are assembled. With siphon pumping that is also known as airlift pumps, the rotating sludge scrapers which are peripherally driven can be designed like an option or along with submersible pumps.
They can be used at wastewater treatment plants, industrial wastewater treatment plants, pulp & paper mills, etc. to remove settled sludge from the clarification tank floors.
