Sodimate’s MBV lime and sludge mixer features orientable paddle blades that thoroughly mix lime and dewatered sludge coming from dehydration systems. The mixer can be combined with sludge conveyors, sludge pumps and lime feed systems for an effective sludge stabilization process. The unit’s robust stainless steel construction makes it versatile for many harsh industrial applications and can be trailer-mounted for remote treatment areas.
Seepex offers a piping contained cake transfer solution to replace open-air conveyor methods. The pitch, diameter and speed of the auger pushing cake into the pumping element can be adjusted to match the application, while load cells automate the process. The hopper is fitted with sensors that detect weight increases and adjust the speed of the pump accordingly, saving energy. The system is also fitted with a pressure sensor, dry running protection sensor and boundary layer injection system. An engineered control panel is included to ensure properly functioning components.
Toro Equipment’s Draco filter presses are used to separate solids from liquids in a wide range of applications. The sludge is pumped into a series of filter chambers fitted with a permeable filter cloth on both sides. While the liquid is forced out of the sides, the filter cloths retain the solid components, leaving a filter cake deposited inside the chambers. As the chambers become full of solids, the pressure rises, and it becomes progressively more difficult to continue pumping in more of the sludge.
Atlas Copco has introduced a new small range of WEDA pumps to provide fast and efficient dewatering. The WEDA04 and WEDA08 provide drainage pumping, with the WEDA08S for sludge pumping and the WEDA04B for low suction pumping. The 08S is designed for difficult sand and mud applications. Equipped with a 750-watt electric motor and a vortex cast-iron impeller, particles and debris up to 25 millimeters can go through the pump housing with minimal wear. The sludge pump’s three-bolt disassembling design makes it easy to maintain.
Moyno’s EZstrip TR Muncher® offers a solution to solids grinding and sludge conditioning. With the ability to maintain the grinder in place without removing the equipment, maintenance is reduced by more than 70%. It features equal thrust offset cutters that capture and reduce large solids for effective maceration; an angled cutter stack “upflow” design that rejects hard materials; a cantilever design that eliminates the need for lower mechanical seals or bearings; a built-in trash trap that can catch any rejected materials; and a PLC to protect against damage.
Markland’s automatic sludge blanket level detector monitors and controls interface levels in sedimentation basins and clarifiers, as well as automates sludge removal when treating wastewater biosolids. It allows users to program desludging pumps to operate only when necessary, preventing carryover, optimizing feed density for improved filter press/centrifuge performance, and bettering outflow for reuse. In DAF units, it adjusts the surface skimmer speed, and in SBRs, it controls the decant valve to minimize cycle times.

The Onyx Isolator Ring provides a simple method to measure the pressure of slurries, raw sewerage, sludge, lime slurry, and other noxious and corrosive fluids. The PSW series is compatible with flanged pipe connections. Nesting inside the bolt circle of mating flanges provides accurate alignment and minimum weight at the lowest installed cost. The inside diameter of the PSW precisely matches standard pipe for smooth, unobstructed flow, self-cleaning operation and minimum turbulence and friction. The rings are available in sizes from 1/2” to 42”.

Bio Energizer® from Probiotic Solutions® is a specialized Micro Carbon Complex used in industrial systems to reduce sludge, odor, BOD/COD, FOG, and costs in wastewater treatment plants and lagoons. The product biochemically oxidizes sludge in wastewater lagoons while remaining online and continuing to work, further reducing the lagoon sludge blanket without the need for draining, drying, dredging, handling, or hauling. When used in activated sludge plants, it can increase volatile solids destruction and improve decant volume and settleability for greater digester and reactor capacity.
The Dimminutor® from Franklin Miller provides effective, automatic screening and grinding of wastewater solids in straight-through channels and wet wells. The unit reduces plastics, wood, rags, and other solids to fine bits, enhancing plant operation and improving the reliability of pumps and other downstream equipment. As its three bidirectional rotary cutters intermesh at close clearance with stationary cutters, solids are finely reduced to a size small enough to pass through a sizing screen. The Dimminutor has an intrinsically open design to handle high flow rates with low head-loss.
Bredel hose pumps reliably handle harsh materials, including abrasive slurry, making them ideal for feeding primary or thickened sludge to digesters or filter presses. Advanced hose technology enables Bredel pumps to handle very viscous grit-filled sludge dependably for extended periods of time. Peristaltic hose pumps are virtually maintenance-free, with no expensive seals to replace, no check valves to clog, and no rotors and stators to wear. Unlike other pump types, the highly abrasive nature of sludge does not affect pump life.
