On the Edge, The Ellis Rotating Belt Screen may be able to get you in compliance at a lower cost than traditional wastewater treatment systems. If you are at your discharge limitation and do not have enough space for a full-scale wastewater system, the belt filter dewatering system could bring you into compliance.
- Up to 32% Total Suspended Solids removal
- Up to 43% Fats, Oils, and Grease removal
- Filters Fibers without plugging
- Solids Dewatered Before Disposal
- Predictive Analytics
HOW THE ROTATING BELT SCREEN WORKS
The Rotating Belt Screen utilizes a continuously rotating filter belt to separate solids from the influent ideal for sludge detwatering. The RBS is effective with a wide variety of wastestreams with screen openings between 65 and 300 microns. The continuous belt screen receives influent wastewater in an enclosed tank, which is then filtered as the filter belt comes out of the water tank. The solids residue is then conveyed above the tank liquid level, to a belt cleaning section and then removed by water spray and dewatered using a screw auger. The dewatered solids or cake can discharge to a container or to a conveying system to a solids disposal container for easy disposal.
This wastewater filtering technology can also be used with wastewater treatment chemicals such as coagulants and/or flocculants to break oily emulsions found in the wastewater. Oils and Greases, Heavy Metals, Heavy Solids, and Insoluble BOD and COD concentrations can be reduced from the wastewater discharge.
Unlike a vibratory shaker screen that can blind with varying wastewater solids, the RBS utilizes a water spraying system to keep the filter media clean and prevents blinding. This feature minimizes the time spent by a maintenance operator required to keep the technology functioning.
