Hydranautics membranes are energy-saving polyamide membranes that deliver higher productivity, rejection and flow rates with reduced biofouling, colloidal fouling and an enhanced ability for cleaning.

 

These membranes deliver solutions for communities who suffer from naturally high boron levels or for manufactures who are faced with boron contamination issues. Hydranautics membranes feature an increased active surface area for higher flux and rejection along with a superior boron rejection rate.

Hydranautics membranes continuously meet and satisfy the increasing demands of the water treatment industry through their high productivity, outstanding performance, salt rejection, productivity, and savings.  These membranes set high performance standards for the reverse osmosis membrane elements which deliver the highest salt rejection rates available. They 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 salinities worldwide with dependable field-proven performance.



Hydranautics membranes 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. These membranes are manufactured with a thicker brine spacer which reduces the Delta P, meeting the increased demand for reduced fouling membranes. This permits a lesser need for frequent cleanings while maintaining a high permeate flow.
