Fournier Rotary Press
The Fournier Rotary Press is automated and requires minimal supervision. The variable-speed flocculator diminishes polymer usage, resulting in cost reduction and improved cake dryness. Low rotation speed reduces wear and tear. It does not require any wash water during operation. Modular design accommodates growing needs by adding extra dewatering channels in the future to increase production without any added footprint or change in process design. 800-463-6328; www.fournierdewatering.com
In the Round Dewatering horizontal drum
The horizontal biosolids dewatering system from In the Round Dewatering provides the flexibility of dewatering at different locations and transporting dewatered solids to any unloading location. Open the door, raise the hoist and material comes out. The unit has a 12-inch auger permanently secured to the floor of the drum. The unloading process begins when the hydraulic power pack is connected to the hydraulic motor that turns the auger, then the drum rotates in the opposite direction, allowing the material to slide into the auger and have a controlled rate of discharge. The drum rotates one turn every two hours overnight, then material is liquid-free in the morning. The unit has a power flex nozzle that is inserted after the drum has been emptied to wash the entire drum in 30 minutes. The unit is constructed of a stainless steel drum sitting on heavy-duty roller bearings on a powder-coated frame and lined with PVC filter tiles. 317-563-2072; www.itrdewatering.com
RNV Hydrovac2
The RNV Hydrovac2 can be placed on an RNV-approved 6-cubic-foot steel construction-grade wheelbarrow to create a portable hydrovac. It can vacuum down vertically to 12 feet to convey effluent sludge, sand and small aggregate. It can be combined with a pressure washer or air spade for another excavation solution. The unit weighs 42 pounds, requires a 120-volt AC, 15-amp power outlet and will run on a 2,200-watt generator or inverter. 607-786-2139; www.rnvac.com
