Hydranautics RO Membrane
Hydranautics RO Membrane
Hydranautics RO membrane is known for its performance and productivity and for continuously meeting the increasing demands of the water treatment industry. It has an excellent salt rejection  and savings. These membranes set high performance standards for the reverse osmosis membrane elements which deliver the highest salt rejection rates available.
Hydranautics RO membrane lower fouling in waste and surface water while having a high fouling potential for reuse and reclaimed applications. These membranes offer superior membrane technology to lower membrane fouling and treatments to treat difficult feed and municipal wastewater. To this point, these applications have significantly required a pretreatment before exposing them to a composite polyamide membrane.
The Hydranautics RO Membrane can range in size from 4†to 8†elements, delivering the highest levels of salt rejection and an always pure end product. They are designed to accommodate varying levels of seawater salinity worldwide with dependable field-proven performance. The Hydranautics RO membrane is manufactured with a thicker brine spacer which reduces the Delta P, meeting the increased demand for reduced fouling membranes. Which maintains a higher permeate flow and permits a lesser need for frequent cleaning.
Hydranautics RO Membrane Features
- High Rejection
- Sea Water Membranes
- LFC Membranes for Low Fouling
- SanRO Membranes for Sanitary or Full Fit
Hydranautics RO Membrane Elements
ESPA:Â Â Low Energy/High Flow Tap & Brackish Water Thin Film Membranes
Energy required to pressurize Reverse Osmosis feed water is the largest contributor to the total energy consumption of the Reverse Osmosis System. As a result, chlorine tolerant membranes have helped the membrane technology become affordable and cost effective by reducing energy consumption required to operate Reverse Osmosis water treatment system. ESPA membranes are the choice for applications demanding high-energy efficiency, with un-compromised productivity and salt rejection.
