DTRO disc tube Membrane sheet for Landfill Leachate / High TDS / high conductivity liquid
The DTRO membrane cushions are made of two single membrane discs with an intermediate layer (permeate spacer). The material of intermediate layer is polyester. Using the most advanced ultrasonic technology for seals.which has been proven over many years in different membrane types & membrane applications.
Membrane cushion types for disc tube technology (RCDT module) in two membrane shapes:
1. Round shape
2. Octagonal shape
Membrane Cushion drawing
All membrane sheet we used for disc tube RO are manufactured by the most professional membrane manufactur in USA. The highest membrane sheet quality can guarantee the best performance.
