A difficult problem that is not commonly thought about is the wastewater from landfills, known as leachate. With the ever growing population, this is a rapidly increasing concern around the world, particularly because of how volatile the leachate tends to be in most cases, making it difficult to filter efficiently. However, this is not a problem for Lighthouse with our state of the art filtration systems. To start, any bacteria in the influent wastewater would be removed by disinfection, typically with ultraviolet light, which would then flow to our Plate Clarifier with an attached flocculation tank to precipitate and remove any larger suspended solids in the stream. From the Plate Clarifier, the stream would then flow into one of our Volcano series filters for finer particle removal. At this stage, the effluent stream should be purified enough to meet any government regulation requirements, however, if further filtration is needed to remove more of the dissolved solids, then a Lighthouse recommended reverse osmosis system may be implemented. This is not typically done due to how quickly fouling occurs in the membrane from the degrading qualities of the leachate including conductivity, organics, and scaling inorganic elements such as CaSO4, Si, Ba. Addition of this final step will more than guarantee a pure effluent.
