Made for indoor or outdoor use, it can save valuable indoor square footage or eliminate the need for additional building space by installing the system outdoors. The covers are custom made to cover standard 20-, 30- and 40-yard dumpsters, with an overall footprint barely larger than a standard dumpster. The shaftless option uses replaceable ultra-high molecular weight liners that will reduce screw wear. The shafted option can be used for increased efficiency and has easily accessible grease points. 973-366-6556; www.jdvequipment.com

Jim Myers & Sons bottom-discharge truck load-out stations

Bottom-discharge truck load-out stations from Jim Myers & Sons are typically loaded by conveyor, pump, or directly from dewatering equipment. These systems provide storage until biosolids can be discharged into transportation vehicles. Stations generally include a hopper and potentially additional conveyors or pumps. The discharge rate of biosolids into trucks is controlled by a combination of one type of discharge method coupled with slide or knife gates. Systems are optimized to prevent plugging, bridging, and rat-holing; and in most cases, to evenly distribute material within the hopper to fully utilize available capacity. Engineers can provide assistance in sizing custom equipment for the application, taking into account angle of repose, material characteristics, and loading/discharge points of a given project. 704-554-8397; www.jmsequipment.com

Paxxo Longopac Fill

The Longopac Fill continuous bag system from Paxxo can connect to the discharge point of machines used to move, dewater or compact screenings, grit and biosolids.

Monitoring systems prevent costly overfeed conditions and enable the documentation of the actual amount fed, which keeps the plant in compliance with federal and state reporting requirements. Users can remotely monitor from SCADA or PLC. The unit is available with the SOLO G2 digital display or with the advanced Wizard 4000 chemical inventory management system. 800-893-6723; www.forceflow.com

Operators Unlimited custom chemical feed systems

From wasted chemicals to permit violations, operational efficiency can be controlled and maximized through proper chemical dosing. Operators Unlimited designs custom chemical feed systems for all areas of the facility. Cooling towers, boiler water, process and solids all benefit from proper dosing. If a chemical feed system is improperly designed, the facility could face several issues including permit violations, increased operational costs, increased maintenance costs and additional labor costs. The plant could potentially overuse chemicals, thus contributing to safety issues, waste and create a system performance issue. An issue in performance can lead to more repairs and the need for replacement parts. As a result, the plant could suffer downtime with consequences for the entire manufacturing facility. Therefore, the design and implementation of a quality chemical feed system that releases the correct amount of chemicals for your exact wastewater treatment needs can be an essential component of a treatment facility. 864-228-1131; www.operatorsunlimited.net

Composting Equipment

Roto-Mix 1220-20 

The Roto-Mix 1220-20 horizontal rotary compost mixer has a mixing capacity of 1220 cubic feet and can hold a maximum load of up to 36,000 pounds. It is designed to thoroughly mix materials to ensure rapid decomposition to produce quality compost. This rotary compost mixer, equipped with a GeneRation II Staggered Rotor Mixer, will uniformly blend materials in a tumbling action that does not pack material and helps introduce air into the mix. The rotor lifts the material past the wedging point of the lower side auger, resulting in an aerated mixture while lowering power requirements. Total movement of material in the mixing chamber eliminates dead spots that are common in conventional auger mixers. Optional conveyors allow for the discharge and distribution of mixed nutrients with microorganisms into static compost piles or windrows. It is available in truck or stationary units. This size of mixer works well with large volume composting operations. 620-225-1142; www.rotomix.com
