Product Description

RisingSun Membrane can offer Reverse Osmosis Elements with ultra-high pressure, High rejection.
Cross replacement: Dupont DOW Specialty membrane XUS180808

Benefits are as below:

1. Up to 120 bar (1,740 psi), ultra-high feed pressure capability due to distinct element and membrane design
2. Increasing the overall efficiency of Zero-Liquid-Discharge (ZLD) by achieving very high solute concentrations thus helping to reduce the size of downstream thermal treatment
3. Excellent for recovery of salts in process streams
4. Robust DOW reverse osmosis (RO) membrane sheet;
5. 31 mil feed spacer to lessen the impact of fouling on the pressure drop across a vessel and to enhance cleaning effectiveness.

Special Membrane Feed Spacer

We 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.
