DOW Vontron Reverse Osmosis RO Membrane For Water Treatment System

Ⅱ. Descriptions:

Reverse osmosis (RO) membrane technology is recognized as the most effective and economical key component in the treatment of natural brackish water and seawater, whether used in small-scale systems or giant water treatment systems.

The membrane element is a spiral roll structure, which is referred to as roll structure for short. The utility model is composed of a multi leaf membrane bag. Each leaf membrane bag is composed of a membrane opposite to the front of two membranes, a product water flow channel placed between the two membranes and a turbulent grid water inlet channel placed on the membrane surface. The three sides of the membrane bag are sealed with adhesive, and the fourth side is opened on a perforated water production collection pipe. Compared with other element structures, such as tube type, plate type and hollow fiber type, it has many advantages, such as uniform water flow distribution, high pollution resistance, low replacement cost, simple external pipeline, easy cleaning, maintenance and large design freedom. It has become the main membrane element structure at present.

IV Application:

There are different models of membrane components, and each model is specific to different applications and service conditions.

*Model BW30: FRP wound standard low-pressure brackish water reverse osmosis membrane element is mainly used in multiple series reverse osmosis systems with high desalination rate.

*Model ULP: Ultra low pressure series membrane elements can achieve the same high water flux and high removal rate as conventional low pressure membranes under ultra-low operating pressure. Its operating pressure is about 2 / 3 of that of conventional low-pressure membrane, and the removal rate can reach 99.5%.

*Model LP: Low pressure series membrane elements are mainly used for desalination of brackish water. They have the characteristics of low-pressure operation, high water yield and good desalination performance. It has high performance of removing soluble salts, TOC and SiO2, and is suitable for the preparation of high-purity water in electronic and power industries.
