Landfill Leachate Treatment for Industrial Applications

Globally, leachate from landfills or municipal solid waste incineration power plants contain high concentrations of chemical oxygen demand (COD), biochemical oxygen demand (BOD), dissolved salts, ammonia, nitrogen, and heavy metals, making it one of the most challenging wastewater sources to treat.

Reverse osmosis and nanofiltration membranes are a barrier to soluble salts, inorganic molecules, and organic molecules, making it highly effective at removing contaminants in the leachate treatment process. However, leachate is prone to cause fouling of membranes, requiring frequent clean-in-place (CIP). This shortens the lifespan of membranes and leads to instability in the quality of the permeate water.

FilmTec™ nanofiltration elements benefit from robust, expertly designed and optimized membrane chemistry to help enable reliable performance over an extended element lifetime. Our FilmTec™ elements can assist in overcoming challenges in the leachate treatment process, helping to achieve consistent permeate water quality through excellent COD and color removal, while partially removing hardness. In addition, the elements feature robust, fouling-resistant membranes capable of withstanding cleanings over a broad pH range (pH 1–13) without impacting on the product's integrity or lifespan.
