Dewatering Equipment

Bright Technologies, Division of Sebright Products, 0.6-meter skid-mounted belt filter press

The compact 0.6-meter skid-mounted belt filter press from Bright Technologies, Division of Sebright Products, has stainless steel frame and roller construction, as well as radius wedge zone and wing roller for sludge dewatering. Components include a sludge pump, polymer system and wash-water booster pump. Options include a sludge flowmeter, air compressor and discharge conveyors. The compact walk-around skid design can be utilized in as little as a 10-by-20-foot floor area. The Boerger rotary lobe sludge pump has a maintain-in-place design offering ease of maintenance. Cake solids of up to 35% can be achieved. Rates of 25 to 50 gpm make it ideal for small applications or when a processor has outgrown dewatering containers. 800-253-0532; www.brightbeltpress.com.

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, 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. 317-539-7304; www.itrdewatering.com.

JWC Environmental Monster Wash Press

The Monster Wash Press from JWC Environmental cleans and compacts the discharge from screens, separating water and organics from the solids. Its Muffin Monster grinder preconditions screenings before entering the press. The grinder breaks open rags, plastics and trash to promote washing and removal of soft organics. The rotor paddle in the wash zone agitates the material to enhance water penetration throughout the debris for better removal of organics from the solids. Organics are washed back into the wastewater treatment process, while the solids are compacted into a dry, less-odorous solid plug. The press is designed for easy maintenance. The rotor and field-replaceable screen can be removed from the top of the unit, minimizing the clearance space needed around the unit during maintenance. A grinderless version is available. 800-331-2277; www.jwce.com.

Industrial Flow Solutions BJM Pumps KZN Series

The BJM Pumps KZN Series of pumps from Industrial Flow Solutions is designed for difficult slurry, sand and sludge pumping applications. Pumps are constructed with an abrasive-resistant 28% chrome iron (600 Brinell, 57 Rockwell C) impeller, wear plate and agitator. In addition, pumps have Class H motor insulation with integral amperage and temperature overload protection, double silicon carbide mechanical seals in a separate oil-filled seal chamber, a heavy-duty lip seal to protect the seal chamber from solids migration, and a hardened ductile iron volute with 300 Brinell hardness for twice the abrasion resistance of standard ductile iron. The largest model has a maximum 22.75-inch diameter, allowing it to fit in tighter spaces than side-discharge pumps. 860-399-5937; www.flowsolutions.com.

DIGESTER

Bionetix International BCP12

The BCP12 anaerobic digester from Bionetix International contains facultative anaerobic bacteria with a total count of 5 billion CFU/g that can digest sludge aerobically and anaerobically. They can be used for reduction of mass and volume of sludge in aerobic, anaerobic and facultative lagoons. Bioaugmentation with BCP12 can increase the efficiency of overloaded treatment systems by breaking down proteins, carbohydrates and lipids mostly through hydrolysis and further through acidogenesis. In addition, bioaugmentation reduces unpleasant odors. It also increases the production of biogas, increasing wastewater treatment plant productivity. It is applied to the primary digester, and application rate is based on digester volume. 514-457-2914; www.bionetix-international.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; seven-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 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

Enviro-Care BEAST 

The BEAST septage, FOG and sludge screening system from Enviro-Care is engineered specifically for heavy debris-laden sludges such as septage. It is designed for fast truck unloading, eliminating the need for rock traps or grinders. It is extremely forgiving when screening FOG, and has all the tools to adjust to the viscosity and debris content of each load it processes, meaning mixed loads are not a problem. At its core is a tank-mounted, perforated plate, rotating drum screen with 6 mm openings. A dual drive system allows the screen and the discharge auger to run independently to maximize capture and remove solids faster. 815-636-8306; www.enviro-care.com.
