Innovative roll-off container solutions like those below are designed to enhance the efficiency of sludge and waste management processes. From compact units that facilitate rapid dewatering and sludge volume reduction to self-contained units offering operational independence at pumping sites, the industry is gearing toward more effective, versatile and environmentally sustainable practices. This array of roll-off containers not only addresses the need for efficient waste management but also highlights the sector's commitment to embracing modern technology for improved service delivery.

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 SludgeKing II
The SludgeKing 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
