Nanofiltration membranes for water treatment

Tubular Material Separation Membrane

Products Introduction

• Poseidon spiral tube membrane product registration trademark Spi-Tub-Mem ® (abbreviated as STM) includes pressure type coiled tube membrane components and immersion type coiled tube membrane components. The product types are divided into ultrafiltration membrane, special nanofiltration, and nanofiltration membrane (STM-NF) series products, The interception molecular weight includes three commonly used interception molecular weight nanofiltration membranes: NF300, NF500, and NF1000, as well as special nanofiltration membranes that only remove organic matter without desalination.

Product features

• It can effectively remove specific molecular weight organics in industrial reverse osmosis concentrated water and garbage leachate nanofiltration or reverse osmosis concentrate under low-pressure conditions, with only a very small amount of retention of dissolved salts in wastewater, showing excellent deorganization performance. It also has the following characteristics:

• Wider water inlet flow channel, filtration without dead angle, effectively enhance the flow rate of the membrane surface, reduce the concentration of the membrane surface polarization.

• It has high loading density, which effectively improves the filtration efficiency and reduces the floor space of the equipment.

• Strong anti-pollution ability, stable operation and low energy consumption.

• Has low investment and operating costs.

Fields of application

• Material Concentration and Separation

• COD Removal from Reverse Osmosis Concentrate

• COD removal from waste leachate concentrate

• Separation and concentration of organic matter in industrial wastewater

• Preparation of organic carbon sources from kitchen wastewater
