As a comprehensive technology company specializing in specialized membrane application processes, Tongjie Environmental Protection possesses not only traditional mechanical processing capabilities but also advanced expertise in membrane system integration, automated control systems, and process package design. We offer mature solutions—including industrial pure water systems, seawater desalination plants, landfill leachate treatment equipment, and high-complexity zero-discharge wastewater systems—through OEM services, ensuring all product technical specifications meet international leading standards.
We have implemented over 1,000 flagship projects across demanding sectors including electronics, chemicals, pharmaceuticals, power generation, and municipal infrastructure. Our OEM product lines strictly adhere to ISO quality management standards, with key components sourced from international brand suppliers. Each unit undergoes rigorous triple testing—including pressure tests, water flow tests, and electrical control simulations—before leaving the factory. From membrane module installation and pipeline welding to control cabinet wiring and overall corrosion protection, every detail reflects our professional expertise.
