Product Name: Spacer Tube (ST) Super High Pressure Module for Waste Water Treatment Model NO.: STRO5-8042-H Type: RO Membrane Type: Spiral Max. Operation Pressure: 120bar Feed Spacer: Ladder Type Stable Rejection: 99.5% pH Continuous: 3-11 Construction: Spiral Wound Element with GRP Trademark: RisingSun Transport Package: Wooden Box Origin: China HS Code: 84219990 Product Description RisingSun Membrane's Spacer Tube (ST) Module can be used forsea water desalination and waste water treatment. We can offer either reverse osmosis or nanofiltration membrane sheet in order to deal with different kinds of waste water. Special Membrane Feed SpacerWe use a very special ladder type feed spacer, which only come into marginal contact with their neighbouring membrane sheet. In this way, the spacers are able to minimise the resistance that is exerted on the feed flow.This special design also greatly reduces the build up of fouling materials compared with common element.Special Configuration with flow directionColor InstructionGreen: Feed WateBlue: PermeateRed: Seals and O-ringsOn this ST module the feed is from the top.The feed water is diffused by the top seal plate to send the feed water evenly around the top of the membrane element.The feed water flows down through the membrane element, as it does pure water permeates and flows out thourgh centre collection device into the space around the tie rod and flows down to the permeates outlets.The concentrated feed water is channelled by the bottom seal plate to the bottom HP connection and out of the module.Features1. Spacer tube (ST) module is high strength design, up to 120 bar operating pressure.2. Open feed spacer with low flow resistance and concentrationpolarization.3. Spiral wound structure with more membrane area.4. Membrane is long using life.5. Competitive price and fast delivery.6.
