Mobile Dewatering Truck

The ABCO Industries Mobile Dewatering Truck is a self-contained solution for dewatering private, municipal and industrial sludge. It conditions with a polymer, and the on-board filter system separates solids and liquids. Solids are stored in a holding chamber on the truck and the liquid filtrate along with its useful bacterial cargo is returned to the tank for normal treatment. The solids can be disposed of at an approved composting or land application area. It can be outfitted with a high-pressure jetting system and can be used as a conventional vacuum truck. 902/634-8821; www.abco.ca.

  Low-Profile Holding Tank

The LP0300-HT 300-gallon low-profile holding tank from Ace Roto-Mold, a Division of Den Hartog Industries, is a free-standing rectangular tank for indoor or outdoor, stationary or transportable applications. Three band recesses around the tank facilitate anchoring. Tanks manufactured of medium-density polyethylene with UV stabilizers feature multiple ports and gallon indicators, and are designed to hold all chemicals rated for contact with polyethylene. The tank is 56 inches wide, 95 inches long, and 16 inches tall. 800/342-3408; www.denhartogindustries.com.

  Sludge-Consuming Bacteria

Pro-Pump/SA Sludge Away from Ecological Laboratories is a blend of humic acids, enzymes and bacteria that aids in the rapid and natural reduction of sludge. Adding the solution to a system speeds the natural biological process of live bacteria. It is designed to work in any temperature above freezing. It will help control odors and liquefy sludge in tanks and lagoons to better enable pump-outs and/or land application. It is safe for people, pets and plants. 800/326-7867; www.propump.com.

  Trailer-Mounted Belt Filter Press

The Bright Technologies 1.7-meter trailer-mounted belt filter press system with folding conveyor and operator walkways is designed to service multiple sites. Easily transportable and quick to set up, the unit requires no special lifting equipment. This unit is manufactured specifically for high throughput and flexibility. The dewatering system effectively reduces the volume of septage, liquid and municipal waste to be handled. Options include a stainless steel frame, rollers and pans. Units can be customized. 269/793-7183; www.brightbeltpress.com.

  Rotary Press

The Fournier Industries rotary press introduces sludge to the system under constant pressure. It is first dosed with a polymer and passed through a variable speed flocculator to improve settleability. The sludge then enters a circular dewatering channel that slowly rotates and uses back pressure to dewater the sludge through fine mesh screens on either side of the channel. Dry cake exits and drops down to a collection bin or is conveyed away for disposal. The press then goes through a wash cycle once per day for five minutes to maintain cleanliness. An enclosed design eliminates the need for odor containment and can be expanded from one channel to six to accommodate increased flow. The system requires little operator attention. It can achieve a volume reduction up to 90 percent on grease trap sludge. 418/423-6912; www.rotary-press.com.

  Dewatering Unit

The 30-yard open-top roll-off dewatering unit from AQUA-Zyme Disposal Systems can be filled with 22,000 to 25,000 gallons of wastewater sludge, septic or grease trap waste at 1- to 2-percent solids in about two hours. After draining 24 hours, the unit can be hauled to a landfill or composting facility for disposal. Sludge volume is reduced by up to 80 percent, with reductions to 98 percent in BOD, COD, FOG and TSS. The unit has almost no moving parts, and filter media has a five-year warranty under normal wear and tear. Standard equipment includes a roll-over tarp system; sliding aluminum splash guard; side, floor and center screens; 1/4-inch floor plate; 7-gauge side plates; four door-binder ratchets; eight drain ports with camlock fittings; two inlet ports; and a long-handle scraper. 979/245-5656; www.aqua-zyme.com.

  Roll-Top Roll-Off Sludge Container

Roll-top roll-off sludge containers from Custom Manufacturing store and transport a wide variety of waste. They feature continuously welded seams, a fully gasketed rear door, a knife-edge seal, adjustable hinges, ratchet binders, secondary release grab handles located on bottom side of door, and 3/16-inch walls and floor. Each lid measures 5 feet by 7 feet, with a 1- by 2-inch closed cell gasket. One lid rolls to the bulkhead end and one rolls to rear door end, leaving access to the center of the container. Units can be customized with either a top- or side-hinge rear door. 405/692-6311; www.custommanufacturing.us.

  Filter Press

The Power Pak filter press from Flo Trend dewaters waste streams such as grease trap waste, recovers either the solids or liquids, separates the solids from liquids for disposal, or clarifies the liquid with submicron separation. The system consists of rectangular tubing side rails with stainless steel protective strips welded on top, stainless steel inlet and outlet manifolds with valves, and a weatherproof cabinet with an air over hydraulic control system for opening, closing and pressuring the unit. It can be skid- or trailer-mounted. Additional options include slurry tanks, duplex cartridge filter units, equipment stands, and air compressors and drag conveyors for trailer-mounted models. 713/699-0152; www.flotrend.com.

  Folding-Frame Tank

Portable containment folding-frame tanks from Husky Portable Containment are available in steel or aluminum (single- or double-fold) with several size and material options. They can be used for oil spill cleanup, chemical or fuel storage, potable or wastewater storage, and firefighting. The frames are pinch-free and have Easy Lift Handles for quick folding and convenient removal of liquids. 800/260-9950; www.huskyportable.com.

  Trash Pump

The S4T-2 4-inch trash pump from Hydra-Tech Pumps features integral stainless steel wear plates above and below the impeller. It fits into tight spaces and can be used as a submersible pump or a tank truck flange mount for direct loading or offloading using onboard hydraulics. Requiring only 8-10 gpm of hydraulic flow at pressures to 2,500 psi, it is suited for operating with smaller hydraulic power units. It features a cast and machined hardened aluminum volute, two-vane open-channel impeller, and a stainless steel intermediate shaft with pressed-in-place upper and lower bearings attached to a heavy-duty gear motor with high pressure lip seal.

  Sludge Dewatering Device

The horizontal sludge dewatering device from In The Round Dewatering features a stainless steel drum with perforated plastic tile lining mounted on a roll-off frame for easy transport and unloading. A typical batch of sludge of 18,000 to 25,000 gallons is mixed with polymer before being filtered in the drum during rotation. The drum is driven by a 1/4 hp variable-speed electric motor with heavy-duty chain and sprocket. Turning action eliminates crusting and wet pockets, producing uniform results. The material dumps easily, and the drum is self-cleaning. The sludge is ready for disposal in one night. 317/539-7304; www.itrdewatering.com.

  Rotary Fan Press
