Disc Tube RO Membrane Based on Simplify Pretreatment for High Fouling Waste Water Treatment

Disc tubular membrane technology referred to as DT membrane or RCDT membrane (Radial Channel Disc Tube membrane module) or PT membrane (Plate Tube membrane module) which is the most advanced products in DT membrane module technology. The most common DT membrane products are (DTRO) and (DTNF).RisingSun Membrane is a successful manufacturer of Disc Tube RO (DTRO) or so called RCDT membrane module mainly for landfill leachate and other high TDS / COD waste water.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 120bar operation pressureSimple pre-filtrationOpen channel configuration enables low flow resistance and low concentration polarization, Minimize membrane scaling and foulingEasy to maintainHigh rejection and high recovery rates with low energy costs (up to 98.0%)Long membrane lifeLower membrane replacement costsHigh quality product waterApplication fields:Treatment & re-use of landfill leachate High concentration of industrial waste waterEffluent & waste water treatment from API, formulation plant & combined effluent from pharmaceuticals industryEffluent treatment from textile industry and dyeing unitPicking & oily waste treatment in steel industryMetal recovery waste recyclingTraditional spiral RO / NF concentrate treatment High COD/BOD waste water treatment (max. COD 20,000ppm)Our advantages:1. Cost is competitive and fast lead time.2. Cross reference: Rochem DT module and PF module3.
