Hangzhou Nanoimp Environmental Technology Co., Ltd., a National High-Tech Enterprise specializing in special separation membranes, continues to expand its high-pressure reverse osmosis portfolio to serve some of the toughest names in industrial wastewater: landfill leachate, waste incineration leachate and high-salinity concentrates.
As the original membrane manufacturer, Nanoimp supplies both membrane elements and complete skid-mounted or containerized water treatment systems, delivering one-stop solutions for material separation and wastewater reuse.

At the heart of the portfolio are two flagship product families. The Spacer-Tube Reverse Osmosis (STRO) line offers multiple models with maximum operating pressure up to 120 bar, maintaining a stable 98.5% salt rejection even under rated high pressure. STRO elements tolerate wastewater that is simultaneously high in salinity and COD, and their wide cleaning pH range of 2 to 12 keeps fouling under control for stable long-term operation.
The Disc Tube Reverse Osmosis (DTRO) line also operates at up to 120 bar with salt rejection above 99%; its open disc channel structure tolerates high suspended solids without clogging, achieves high concentration ratios with less waste liquid, and allows single-disc replacement - a maintenance advantage that directly cuts downtime and cost.
Element construction reflects serious engineering: polyamide TFC composite membranes housed in glass fiber reinforced composite (FRP) shells, with parallel flow passages of 47 mil and alternative dimensions available for special projects. Typical models include the STRO 8042-90-ZE for waste incineration leachate and the STRO 8042-75-TP compact unit element.
Beyond elements, Nanoimp offers ODM manufacturing for engineering companies: process, layout, piping and electrical control are tailored to the customer's water quality, power supply and site conditions, and every system passes a factory acceptance test (FAT) before shipment with full bilingual export documents. Global branches provide pilot tests, 24-hour after-sales support and remote system monitoring.
EPC contractors and industrial end users facing refractory wastewater are invited to send inquiries and experience a membrane partner built for extreme conditions.
