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

Roll-Off Containers

AQUA-Zyme Disposal Systems ADS

The ADS 30-yard open-top roll-off dewatering unit from AQUA-Zyme Disposal Systems can be filled with 22,000 to 25,000 gallons of biosolids at 1% to 2% solids in about two hours. After draining for 24 hours, the unit can be picked up using a standard-capacity roll-off truck and transported for solids disposal. Sludge volume can be reduced by 80% with reductions to 98% in BOD, COD, FOG and TSS. Effluent is clear, the unit has few moving parts, and the size of filter media can be selected according to job requirements. Standard equipment includes a roll-over tarp system; side, floor and center screens; 1/4-inch floor plate; 7-gauge side plates; four door-binder ratchets; eight drain ports; two inlet ports; and a long-handle scraper. Units are also available in a 15-yard size. 979-245-5656; www.aqua-zyme.com

Bucks Fabricating Dewatering-Style Roll-Off Containers

Dewatering-style roll-off containers from Bucks Fabricating feature a removable perforated steel basket that filters the materials within, separating the liquids to the bottom while the sludge materials remain on top. From there, the fittings, or apertures, commonly located on the bottom of the sealed tailgate allow the hauler to drain the liquid from the container. This process decreases the container payload. Available in cable, hooklift, combo or permanent-mount hookups, dewatering containers are manufactured in standard and custom sizes. 800-233-0867; www.bucksfab.com

Park Process Sludge King II

The Sludge King II roll-off dewatering container from Park Process incorporates an engineered design that eliminates trapped water in the bottom of the filter cake. The second center wall filter increases filter area by 33% producing drier cakes in less time. The plastic floor panels that cover the floor space between wall filters and center wall filters serve three purposes. They hold down the bottom of the filter elements, help eliminate standing water and aid in filter cake dumping. The inlet manifold is split into three inlets, each with a ball valve, allowing incoming flow to be distributed evenly into the three compartments formed by the two center-wall filters. 855-511-7275; www.parkprocess.com

Screens/Strainers/Screening Systems

JWC Environmental Honey Monster 

The Honey Monster septage receiving station and FOG receiving system from JWC Environmental is designed to ease the management of septage waste for the wastewater plant operator and the hauler. It quickly screens and processes septage, grease, FOG and sludge from vacuum trucks. The automated septage acceptance plant provides for cleaner handling of septage truck waste by reducing and separating unwanted solids such as rocks, rags, clothing, plastics and other trash, according to the maker. The combination of grinding, solids removal, washing and dewatering allows a typical septage truck to unload in 5 to 15 minutes. It is completely enclosed to ensure safety, vector control and containment of foul odors. The optional MonsterTrack metering and control system uses a flowmeter to track septage and provide accurate billing data for the facility and a receipt for the hauler. 800-331-2277; www.jwce.com

Lakeside Equipment Raptor Septage Acceptance Plant

The fully automated Raptor Septage Acceptance Plant from Lakeside Equipment is designed to remove debris and inorganic solids from septage tanks, grease traps, sludge, leachate and industrial waste. It includes the Raptor Fine Screen, which compacts and dewaters the captured screenings to a solids content of 40%. The screen’s rotating rake teeth penetrate the cylindrical screen bars, which prevents plugging and binding from grease and small debris. This allows for faster unloading times. The Raptor Acceptance Control System is a security access station that can be integrated to allow authorized haulers to unload their waste at the facility. Adding the data management and accounting system with the RACS station provides capabilities to track and invoice customers. 630-837-5640; www.lakeside-equipment.com
