Leachate Treatment Project for Landfills in Sichuan

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…

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 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 This project is a high-salinity wastewater treatment system for coal mines, with a capacity of 5,000 m³/d. The main process includes: Pre-treatment clarification + Ultrafiltration system + Stage BWRO (Brackish Water Reverse Osmosis) system + TMF (Tube Module Filtration) microfiltration + Secondary BWRO + TM microfiltration + Tertiary STRO (Seawater Reverse Osmosis) +…
