Choose Plum Membrane Technology for end-to-end membrane solutions built around our self-developed PEK tubular membranes, covering industrial wastewater and Fluid membrane Separation.From pretreatment and salt-splitting nanofiltration (NF) to HRCC high-ratio concentration and ZLD, we deliver shorter flowsheets, steadier operation, and lower OPEX—helping you achieve compliance and reuse while increasing yield and purity.
Company Introduction
Advancing Membrane Technology — From Development to Application
Plum Membrane Technology Co., Ltd., established in 2004 and located in Hefei’s Xinzhan Hi-Tech Zone, focuses on two areas—industrial wastewater Zero Liquid Discharge (ZLD) and Fluid membrane Separation—and delivers end-to-end solutions from lab validation to full-scale engineering implementation. Our scope covers membrane-element R&D and manufacturing, complete systems (skids), process design, installation & commissioning, and after-sales service. Core technologies include PEK tubular membranes, nanofiltration-based salt separation, and High Recovery Continuous Concentration Reverse Osmosis Technology (HRCC Technology).
Core Technologies
Plum Membrane’s core technologies are built on self-developed PEK tubular membranes, enabling robust pretreatment, precise salt fractionation by nanofiltration, and ultra-high recovery concentration through HRCC RO.
These technologies form an integrated technical platform for industrial wastewater ZLD and advanced fluid membrane separation.
Projects
Plum Membrane has delivered complex projects across multiple industries—from clarifying and purifying fermentation/hydrolysate streams to Zero Liquid Discharge (ZLD) for high-salinity wastewaters. Powered by our self-developed PEK tubular membranes, Continuous UF & NF Salt Separation, and High Recovery Continuous Concentration Reverse Osmosis Technology (HRCC Technology), we help customers handle challenging feeds, achieving reliable compliance and high-efficiency reuse.
