Liquid Waste Technology LLC
The Liquid Waste Technology, LLC (LWT) Pit Hog Remote Control Electric Lagoon Pumper (Model PH10-40hp) dredge is designed to remove sediments from the bottom of waterways, settling lagoons and ponds. In situ solids are excavated and transported as slurry through a piping system to a remote location. The material excavated is normally land applied, trucked or dewatered.
Foam filled, steel pontoons provide the necessary flotation to support the machinery and equipment in the waterway. Principle features include the auger head, submersible pump, boom, boom hoist, traverse winch and hydraulic system. The auger head and the submersible pump are essential to effective solids removal. The boom hoist vertically positions the auger and submersible pump in the sediment while the traversing winch propels the machine forward and backward along a wire rope cable anchored at both ends. This proven design provides a cost-effective means for hydraulically dredging sediments.
Prior to operation of the dredge, an anchored cable harness is established for positioning and propelling the unit in the waterway. Generally, the harness is comprised of two lateral cables located on opposite sides of the pond with a traverse cable stretched between them. The traverse cable is threaded through the treble sheave winch and cable guides on the unit which, after pre-tensioning the cable to remove the slack, propels the unit forward and backward. After the floating discharge hose and/or pipe are connected to the dredge, it is ready to operate. Generally, solids are excavated while traversing forward only.
All dredge functions can be remotely controlled from shore using a hand-held transmitter, or run via complete automation developed by LWT. A series of switches on the transmitter enable the operator to start and stop all equipment as well as set the speeds of the slurry pump and winch traverse.
LWT’s automated and radio remote controlled dredges use Bottom Sense to protect pond bottoms and liners, Solids Sense to maintain delivery of a constant solids density and other options, such as Radio Remote Sense, Auto Sense and Lateral Sense.
The dredge is designed with quality components for dependable, easy operations and built with structural steel for dependable, long-term use. It utilizes electric power, can be manned or unmanned, and can be operated by computer or manual controls.

Siemens Water Technologies
The new E-Ball environmental ball system from Siemens Water Technologies consists of multiple hollow plastic balls that are used to create a floating blanket to cover virtually any water surface, including manure ponds and tanks. The plastic balls, which come in a variety of sizes and construction materials, typically measure 100mm in diameter, weigh 220g and are made of medium density polyethylene. The low thermal conductivity of plastic, combined with air held in the ball, creates a thermal insulation barrier over the water surface.
The E-Ball system components feature a thick wall construction that is approximately 10mm thick, yet floats with about 40 to 50 percent of the ball surface submerged to optimize the insulating effect and minimize the chance of the ball blowing out of the tank. The heavy-weight construction also eliminates the need for plugs, seals, or ballast. Totally maintenance-free, the E-Ball system components will not leak or sink. Ultraviolet stabilizers protect the plastic from degrading in the sunlight.
The environmental balls form a close-packed configuration and stack up or spread out in sloped basins to maintain total surface coverage as the water level changes. The balls also automatically conform to the shape of equipment and basin structures, allow normal movement of equipment through the liquid and do not impede installation of monitoring probes or water sampling.
The E-Ball floating tank and lagoon cover reduces odors substantially. It can be used as a stand-alone product or combined with floating surface aerators and mixers or other aeration and mixing technologies.
Engineered Storage Products Company
Slurrystore, a division of Engineered Storage Products Company, bills itself as being the number one above ground manure storage system on the market. The company provides three different models of above ground, glass coated steel manure storage tanks – Model 90A, Model 96A and Model 2000. All structure components:
• are glass coated for high corrosion resistance and long life,
