In The Round Dewatering horizontal drum

The horizontal biosolids dewatering system from In The Round Dewatering has a stainless steel drum with perforated plastic tile lining. The drum is mounted on a roll-off frame for easy transport and unloading. Water trays allow containment of 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. The 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.

Park Process Sludge King II

The Sludge King II roll-off dewatering container from Park Process uses filters that turn 90 degrees at the bottom of the container, leaving no standing water in the cake. This also increases the usable area of the filters by 33% over older containers with only one center filter wall. The increased filter surface area and the narrowed sludge compartments formed by the additional filter panel translate into drier cake formed in less time. 855-511-7275; www.parkprocess.com.

Screens/Strainers/Screening Systems

Crane Pumps & Systems Barnes Pressure Sewer EcoTRAN

The Barnes Pressure Sewer EcoTRAN from Crane Pumps & Systems is designed to provide a practical and environmentally safe alternative to traditional gravity sewers. Even in locations with difficult terrain, it reduces sewage infrastructure costs by allowing smaller diameter piping to be used in place of large complex septic sewage systems, making it a suitable sewer choice, according to the maker. It collects and grinds sewage in an underground basin, then transports it to a remote private or municipal wastewater treatment plant. 937-778-8947; www.cranepumps.com.

Duperon Dual Auger System

The Duperon Dual Auger System is deployed in targeted high-ragging manholes/wet wells to remove problematic debris and prevent chronic pipe and pump clogging. Removing wipes at (or near) the point they enter the sewer stops the problem where it starts without impacting downstream operations. The five-in-one system captures, dewaters, compacts, conveys and stores problematic debris in a below-grade discharge pipe where it can be emptied by vacuum trucks. This lets users transform emergency, dirty, unsafe and manual cleanouts into planned, safe and coordinated debris removal by vacuum truck operators. To use, uncover then insert suction tube into the discharge chute, remove debris and landfill. 800-383-8479; www.duperon.com.

JWC Environmental Honey Monster 

The Honey Monster septage receiving station and FOG receiving system from JWC Environmental is designed to ease the challenges of managing septage waste for the wastewater plant operator and the hauler. It quickly screens and processes septage, grease, FOG and sludge from vacuum trucks. This 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 troublesome 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.

ScreencO Systems Trash Master 400 Auto Screen

The Trash Master 400 Auto Screen from ScreencO Systems uses gravity to separate the trash from the flow stream through a 4-inch inlet with a fan spreader to power-offload vacuum trucks. It has an aluminum hopper with a 6-inch outlet cam and 3/8-inch gapped 1/4-inch bar screen that meets U.S. Environmental Protection Agency 503 regulations. A stainless steel U-channel with plastic-lined titanium UHMW provides for years of wear, with a high-strength alloy steel 8 1/2-inch shaftless screw that moves trash to a waste container. The stainless steel U-channel has slotted drain holes and a center channel bar screen for cleaner and dryer trash. A custom-built stainless steel bar rake is included for easy maintenance. A front spray bar with a 1 gpm nozzle keeps the unit clean and free of buildup. A 2 hp NORD gear reduction drive with Lenze variable-frequency drive control accomplishes a variable-speed screw from 6 to 30 rpms. 208-790-8770; www.screencosystems.com.
