Hydranautics 2.5" Brackish Water Membranes

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 reliable 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 pre-treatment 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.

Hydranautics ESPA

Hydranautics membranes proceed to be the most suitable membranes for the growing needs of the water purification industry. ESPA series membranes continue to be the preferred choice for maximum productivity and salt rejection. These membranes provide solutions to remedy even the most difficult water purification problems with unmatched productive capacity, efficiency, and savings.

Benefits:

  • Maximal Productivity
  • More than 99% Salt Rejection
  • Lower pressure for lower CAPEX/OPEX
  • Extended life of membrane due to less fouling
  • Efficient rejection of impurities such as Boron and Silica
  • High tolerance for pH cleaning

Hydranautics CPA

When it comes to maximal performance, composite polyamide (CPA) membranes are viewed as the level of attainment for reverse osmosis membrane elements. CPA membranes offer some of the top-notch saline rejection rates on the market. These membranes provide benefits such as: 

  • More than 99% Salt Rejection
  • Efficient rejection of silica, hardness and TOC
  • High productivity (permeate) flow
  • More than 93% rejection of boron
  • Low levels of biological and colloidal fouling
  • High tolerance for pH cleaning
  • Low energy usage

Hydranautics LFC 

Low fouling composite (LFC) membranes deliver considerable reductions in fouling percentages and increases in membrane productivity by recovering minimal performance after cleaning. LFC membranes satisfy the requirements for treating difficult feed waters of various municipal and industrial applications. This membrane is well suited for the treatment of difficult feed waters for numerous municipal water and industrial applications, which until now needed the utilization of feed water pre-treatment from reverse osmosis membranes. Hydranautics LFC membranes provide benefits such as:

  • High productivity (permeate) flow
  • More than 99.7% Salt Rejection
  • Low levels of biological
  • Lower colloidal fouling
  • Enhanced membrane toughness
  • Less differential pressure
  • High tolerance for pH cleaning
  • Flux distribution upgrade

Applications

  • Municipal freshwater
  • Lowering TDS before ion exchange
  • Creation of ultrapure water for semiconductors
  • Boiler feed water for power & energy
  • Treated water for pharmaceutical usages
  • Recycling of Industrial wastewater
  • Zero liquid discharge
