Highest membrane area RO product with 34 mil spacer

Designers will no longer have to sacrifice membrane area to have thicker feed spacers for high fouling applications. Innovations have enabled us to offer the ESPA2-LD MAX membranes which have a membrane area of 440 ft2 (40.9 m2) and use a 34 mil feed spacer. Increasing the membrane area of a standard 400 ft2 (37.2 m2) by 10%, to 440 ft2 (40.9 m2) offers the following benefits: - CAPEX benefits like reducing the total number of elements, pressure vessels etc. and equipment with smaller footprint - OPEX benefits like reduced energy consumption and lower differential pressure 

Features and benefits

  • Enhanced membrane chemistry for best permeate quality at lower feed pressure
  • Improved chemical resistance for increased membrane life
  • Innovative feed spacer design to reduce cleaning frequency and costs
  • Proprietary vented seal carrier to eliminate pressure-shock damage during system startup 

Applications:

  •  Municipal drinking water treatment 
  • Wastewater treatment 
  • Treated Sewage Effluent (TSE) applications
  • Second pass RO
  • Water treatment for irrigation
  • Bottled water and food and beverages industry
  • Light industrial use for treating water low in biodegradable organics 

Key features:


  •  High permeate flow 12,000 gpd (45.4 3/d)
  • High salt rejection 99.6% (99.5% minimum) 
  • High rejection of TOC, boron, silica and nitrate
  • Lower energy consumption
  • Lower operating pressure, differential pressure
  • Reduced colloidal fouling
