Product Description

RisingSun Membrane's Disc. Tube membrane module includes RO and NF by using different kinds of membrane sheet. The membrane module structure is completed distinct from the traditional spiral wound membrane. With open flow channels, feed flows through the entrance into the pressure vessel and reach the disc in a short distance. Then the feed flows 180 degrees from one side of the membrane reverse flow into the other side of the membrane, into the next disc again and finally runoff from outlet.

This special design makes feed collide with the disc bulge through the membrane surface forming turbulence which increases flow rate and self-cleaning function and long service life of the membrane.

Features:

• High strength design, up to 160bar operation pressure
• Simple pre-filtration
• Open channel configuration enables low flow resistance and low concentration polarization, Minimize membrane scaling and fouling
• Easy to maintain
• High rejection and high recovery rates with low energy costs (up to 99.6%)
• Long membrane life
• Lower membrane replacement costs
• High quality product water

Application fields:

• Treatment & re-use of landfill leachate 
• High concentration of industrial waste water
• Effluent & waste water treatment from API, formulation plant & combined effluent from pharmaceuticals industry
• Effluent treatment from textile industry and dyeing unit
• Picking & oily waste treatment in steel industry
• Metal recovery waste recycling
• Traditional spiral RO / NF concentrate treatment 
• High COD/BOD waste water treatment (max. COD 20,000ppm)
