JMS, Jim Myers & Sons, Mega-SCRAPER hydro-dynamically designed blades and reciprocating motion produce a thickening effect of the sludge blanket while creating a zone of influence that moves solids toward the sludge collection pit. On the forward stroke this blade design transports sludge forward, and slides under the blanket without disturbance of the sedimentation process on the reverse stroke. The speed of the reverse stroke is 2-3 times the forward stroke speed. Based on sound principles, but flexible by design, it is applicable in both water and wastewater sedimentation systems.
Polychem - SedVac Sediment Dredge System is a sludge removal system that cleans the basin floor by removing the compression zone layer of sludge. Unlike clog-prone vacuum pipes, the SedVac system uses triangular header wings with 4-inch-high intakes to significantly reduce clogging. Cable drive that can be easily installed in existing basins, SedVac provides an ideal solution for plants that need to increase capacity without building new tanks or making large-scale alterations. Not only can SedVac handle heavy solids loadings, but it can also handle varying levels of influent quality, making it a perfect system for facilities with typically challenging fluctuations in intake levels.
Polychem -Shaft collector uses non-metallic collector systems that has earned a reputation as the industry standard for performance and reliability. The 3-shaft clarifier system removes bottom sludge only. It is commonly used in drinking water treatment plants and is often combined with inclined plate or tube settler applications.
Polychem - Chain & Flight Collector system removes bottom sludge and transfers it to a sludge hopper at the influent end of the clarifier while also skimming out floating surface scum and discharging it via a scum pipe.
Borger Rotary Lobe Pumps are positive displacement pump transferring sludge to and from thickeners, belt presses, centrifuges, rotary presses, digesters , air entrained fluids, DAF, and industrial slurries. They handle thick solids greater than 2% up to 2000 gpm and pressures up t0 150 PSI. Rotary lobe pumps can run dry and are capable of self-priming. The rotation of the pair of lobes increases suction chamber pressure and creates a vacuum on the priming side of the pump drawing liquid into the pump chamber.
Wemco® - Screw-Flow Pump by Trillium Flow Technologies is ideal for return activated sludge (RAS) service where the pump could perform against a low total dynamic head while operating close to its best efficiency point (BEP) where bearing loads and shaft deflections are at a minimum. The screw-shaped impeller has improved clog-resistance was also required to eliminate maintenance to free the pumps from rags. The screw centrifugal pumps feature a single, spiral vane impeller with no blade edges exposed to the flow. A cutting groove cast into the liner shears off material that builds up around the impeller periphery and re-introduces it into the flow. The screw-centrifugal design provides clog-resistant pumping for trouble free movement of solids, and fibrous and stringy materials. The steep head-capacity curve produced by the impeller provides additional head to help push through any partial blockages.
