When automotive spray robots run batch production or change colors, they use water-based cleaning agents to flush the spray heads, bell cups and lines. Traditionally, the resulting cleaning waste liquid has been shipped out entirely as hazardous waste, at high cost. Plum Membrane’s PEK® tubular membrane + nanofiltration separation process returns more than 80% of […]
→How Does Tubular Membrane Pretreatment Reduce RO Scaling Risk?
Scaling is one of the most persistent problems in industrial reverse osmosis systems. As water recovery increases, dissolved minerals become concentrated and can precipitate on membrane surfaces. Hardness, silica, and other sparingly soluble compounds may gradually restrict water flow, increase pressure requirements, and make cleaning more difficult. For industrial facilities pursuing higher water recovery or […]
→How Do Tubular Membrane Modules Protect Downstream RO Systems?
Reverse osmosis (RO) is widely used for industrial water reuse, desalination, and wastewater treatment, but even a high-performance RO system can struggle when feedwater quality is poorly controlled. Suspended solids, hardness, silica, oil, and colloidal matter can gradually compromise membrane performance, increase cleaning requirements, and limit recovery. This is why pretreatment deserves as much attention […]

→Mine-Water Membrane System Manufactured and Shipped to Project Site
The mine-water membrane treatment equipment completed factory manufacturing and was shipped to the project site in Gansu. Shipment does not mean installation, commissioning, or performance acceptance is complete.
→2,200 m³/d Landfill Leachate Membrane System Completes FAT
A 2,200 m³/d membrane system for landfill leachate and concentrate treatment completed factory acceptance testing. FAT confirms manufacturing and agreed checks; it is not an onsite water-quality guarantee.
