The Light Environmental Inc. Automated Filter can relieve primary treatment burden at wastewater treatment plants in a very small footprint, saving major infrastructure investment and space.
The Automated Filter has a fine screen which removes solids as fine as 15-30 micron. It removes high percentages of TSS and particulate BOD in wastewater. For most municipal applications, this means removal of 40-70% TSS and 30% BOD.
When compared with sedimentation as primary sewage treatment, the Light Environmental Inc. Automated Filter typically requires less than 50% of the capital investment and less than 10% of the footprint.
The Light Environmental Inc. Automated Filter removes solids on a continuous-loop fine mesh screen. As the screen moves, it carries solids out of the flow and drops them into a hopper. An auger press dewaters the collected screenings while screened wastewater flows through the unit.
As the screen rotates, a patented air-blower system forces the retained screenings off the mesh and into the screenings hopper, virtually eliminating solids carry-over. Additionally, a patented hot water wash periodically removes any grease or other solids that may adhere to the mesh.
Light Environmental¡¯s Automated Filtration Systems are compact, completely covered systems which have a small footprint and are easy to maintain. Screenings dewatering and odor containment are integrated parts of the machine.
Our Automated Filtration System can be applied at municipal and industrial wastewater treatment plants to filter unwanted organic and inorganic solids from the wastewater flow.
Our Automated Filtration System cost-effectively reduces the organic load on downstream processes. Reduced load means more capacity in existing plants and smaller downstream processes (with the resulting cost savings) in new plants. With over 240 installations as of 2007, it has been used effectively for: Primary Wastewater Treatment, Membrane Pretreatment, Fishing Industry, Food/Dairy Industry, Pulp and Paper Industry, and Manure Dewatering.
