Dewatering Equipment
BDP Industries DSP Screw Press
The DSP Screw Press from BDP Industries is a heavy-duty option for those looking for dewatering performance in a completely enclosed unit with low energy and water consumption, and reduced operation and maintenance costs. The pivoting basket design allows for increased access for maintenance. Other improvements include the vertical thickener for prethickening, processing flow rates of up to 150 gpm as well as the ability for a small-scale package system capable of 5 to 10 gpm. 518-695-6851; www.bdpindustries.com
In the Round Dewatering horizontal drum
The horizontal biosolids dewatering system from In the Round Dewatering features a stainless steel drum with perforated plastic tile lining. The drum is mounted on a roll-off frame for easy transport and unloading. Trays contain discharge water. An 18,000- to 25,000-gallon batch is mixed with polymer before being filtered in the rotating drum, which is driven by a 1/2 hp variable-speed electric motor with a heavy-duty chain and sprocket. Turning eliminates crusting and wet pockets to produce uniform, consistent results. The dewatered material dumps easily, and the drum is self-cleaning. 317-563-2072; www.itrdewatering.com
Dewatering/Bypass Pumps
Boerger rotary lobe pumps
Boerger rotary lobe pumps are designed to convey septage, sludge and other solids-laden fluids commonly encountered in wastewater and septage management operations. As positive displacement pumps, they deliver a consistent flow while handling viscous and abrasive media with minimal pulsation. The pumps are self-priming and capable of reversible operation, making them suitable for applications such as septage receiving stations, sludge transfer and tank or pit clean-out. Their valveless design allows fibrous materials, wipes and other debris commonly found in septage to pass through the pump with reduced risk of clogging. A key feature of the pump is its Maintenance in Place design, which allows operators to replace wear components quickly without removing the pump from the piping system. This simplifies routine service and reduces downtime. They are used in municipal and industrial wastewater facilities for reliable septage and sludge handling. 612-435-7300; www.boerger.com
Idee e Prodotti TARUA
The TARUA from Idee e Prodotti is a positive displacement pump that simultaneously vacuums water and solids. Unlike conventional systems, it features a full-passage design, meaning everything entering the suction hose passes through the pump body without restriction. No protective filters or grinders are required. Special accessories allow in-line chemical dosing without separate dosing pumps, simplifying treatment. The system operates like a vacuum truck but continuously, with flow rates of 1,060 to 1,766 cfh, and can be coupled with the DRY BOX dynamic gravity dewatering system, installed in a roll-off container. Using filtro-dynamic separation (active filtration) it enables volume reduction and transport in a single step. Applications include industrial and municipal wastewater treatment plants, sewer and pipeline cleaning, drilling sludge management, mining operations and cleaning industrial tanks without emptying them. www.pumps-dewatering.com
Pioneer Pump Minetuff Series
Franklin Electric’s Minetuff Series of electric submersible dewatering pumps from Pioneer Pump are specially designed for deep wells or space-limited sites. The pumps come in 8 to 140 hp and are designed to work in harsh environments from wastewater to mining to construction. Features include heavy-duty motors with integrated thermistors to protect against thermal overload, durable mechanical seals, duplex stainless steel impellers for toughness and corrosion resistance, polyurethane-coated wear parts and light aluminum castings with thick walls for durability. 844-250-4982, www.pioneerpump.com
Zoeller Pump 840 Reversing Grinder Pump
The 840 Reversing Grinder Pump from Zoeller Pump changes cutter rotation with every pump cycle, alternating between clockwise and counterclockwise to minimize the risk of stringy materials wrapping around the cutter. This feature extends the life of the cutter assembly and keeps the system running smoothly. Designed for versatility, it features a 1 1/4-inch NPT discharge that allows for both vertical and horizontal installations. Its rugged, finned cast iron construction and corrosion-resistant, powder-coated epoxy finish deliver lasting durability in demanding environments. The oil-filled, hermetically sealed motor is built with Class F insulation, thermal protection, leak detection and dual shaft seals for reliable operation and enhanced motor life. Plus, compatibility with competitor rail systems makes it a smart, adaptable solution for new or retrofit installations. 800-928-7867; www.zoellerpumps.com
Roll-Off Containers
AQUA-Zyme Disposal Systems ADS Dewatering System
The ADS Dewatering System from AQUA-Zyme Disposal Systems provides an economical solution for dewatering septic and grease trap waste, portable restroom waste and food waste by transferring waste from trucks through a filter into holding tanks. Sludge is pumped from the tanks through a polymer system and into the box, effectively separating solids from liquids. Once drained, solids are disposed of at compost facilities. 979-245-5656; www.aqua-zyme.com
Pik Rite self-contained roll-off unit
Pik Rite self-contained roll-off units are fully operational at the pumping site without a chassis. The heavy-duty front platform holds the user’s choice of pump and a Kohler 25 hp electric-start engine. The tank is set up with a level indicator, rear-sight eyes, 36-inch top opening, 20-inch rear opening, 3-inch intake with an internal 3-inch standpipe and a 4-inch discharge. The low-profile, 12-inch primary shut-off is paired with a 10-gallon secondary shut-off. Spray-on protective liner protects hoses and promotes durability. Work lights and a safety beacon are mounted on the rear tank head, and a ladder is mounted on the side. Polished aluminum hose trays and custom paint finish are standard. Other customizable options are available. 800-326-9763; www.pikrite.com
Screens/Strainers/Screening Systems
ScreencO Systems Mini Screen 400
The compact Mini Screen 400 receiving station features ScreencO’s Dual Screen Design, including 16 square feet of bar screening area. It allows PROs to gravity off load up to 500 gpm through a 4-inch inlet cam or telescope inlet, with a fan spreader deflecting waste down on the screen, making it virtually self-cleaning. The nonmechanical screen uses gravity and flow from the truck to separate the trash from the waste stream. It features all-aluminum construction with stainless steel 3/8-inch gapped bar screens on opposing angles so it will not plug with rags or trash. It offers simple raking to the trash drain tray with stainless steel cleaning tools, making for a simple clean-out to the universal 7-foot folding trash chute assembly, allowing for trash exit in either direction. Built-in forklift pockets make the unit portable, allowing for setup anywhere. 208-790-8770; www.screencosystems.com
Lakeside Raptor Septage Acceptance Plant
Lakeside’s Raptor Septage Acceptance Plant is a self-contained, fully automated unit designed to remove debris and inorganic solids, including grease trap waste, that typically pass through a conventional bar screen. Anchored by the reliable Raptor Fine Screen, the unit is a simple, efficient way to pretreat the increasing amount of municipal, industrial and septic tank sludges processed at wastewater treatment plants. Lakeside’s heavy-duty, three-plane fine screen utilizes a rotating rake that passes through the full depth of the basket bars, removing debris from the screening area. The rotating rake deposits the collected screenings into the central screw conveyor hopper for washing, transport and compaction/dewatering. With the addition of aerated grit removal to the system, the unit is offered as the Raptor Septage Complete Plant. 630-837-5640; www.lakeside-equipment.com
