Dewatering, a vital process in the municipal wastewater treatment industry, helps in the reduction of water content from sludge, making waste disposal more efficient and less cumbersome. Modern dewatering equipment not only facilitates efficient water removal but also minimizes the environmental footprint, reduces transportation costs and ensures compliance with regulatory standards. As municipalities and wastewater treatment plants look to optimize their processes, innovative dewatering equipment offers solutions that combine technology with sustainability. Take a look below to explore some of the leading dewatering equipment available in the market.

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

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

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
