Zero Discharge Project for High Salinity Wastewater in Coal Mining

Project Overview The water treatment project at a food factory in Yibin utilizes municipal tap water as the feedwater. It employs multi-media filtration and activated carbon as pre-treatment methods, followed by reverse osmosis for desalination. The two-stage reverse osmosis membrane system uses Nais “ULP-8040” membrane elements, with a treatment capacity of 100T/H. The quality and…

Project Overview The treatment process is pre-treatment, DTRO membrane unit, freeze crystallization. Seawater is pre-treated and then passed through the DTRO membrane. The brine filtered by the membrane undergoes a freezing process to separate the salt from the water. During crystallization, a significant amount of salt is excluded from the ice crystals, greatly reducing the…

Project Overview This landfill leachate project has a treatment capacity of 120 tph and is characterized by high concentrations of organic pollutants, significant water quality fluctuations, high conductivity, high salt content, and poor biodegradability. The previous approach, which utilized a biochemical process combined with a traditional spiral-wound membrane system, consistently failed to meet the required…

Project Overview The Suizhou landfill leachate project is a technical transformation and expansion initiative. The influent COD reaches as high as 5000 mg/L. Initially, the project utilized a two-stage DTRO (Disc Tube Reverse Osmosis) treatment process, with a designed daily treatment capacity of only 100 tons. However, as the volume of landfill leachate has increased…
