ECO RO Membrane

Features:

• Heron ECO series RO Membrane perform high rejection, super large productivity. The operation pressure is no more than 70% of normal brackish membrane. ECO series of elements can lower your operation and maintenance costs a lot by lowering the requirement of pumps, pressure vessels, piping and other components.
• Heron ECO series RO Membrane consistent, outstanding performance, improved element structure, wide feed spacer channel and short membrane leaf design. Under the condition of ensuring adequate area of the membrane, wider spacer channel will help to discharge contaminants of feed water. The stress-tolerant required of pretreatment and quality required of feed water will be relatively higher when working under Off-Normal condition. ECO series membrane elements have more effective cleaning than normal elements. It can maintain a relatively low Pressure Drop and prolong the span-life of membrane element when the quality of feed water is not good.
• So far, t Heron ECO series RO Membrane is only 4.0 inch in diameter and 40inch in length. One model is high rejection type and the other is large productive type. We will also design different size and specifications membrane elements according to clients requirements in the future.
