Hydranautics CPA7-LD-4040 Reverse Osmosis Membrane 4" x 40"

Product Description

The CPA7 series are the newest CPA brackish water RO membranes offering the highest salt rejection in the industry. These ultra-high rejection RO membranes are meant to fulfil your purest water quality requirements.

Where ultra-high purity water is required under difficult water conditions, the CPA7 membranes supply the best combination of high rejection and high flow capability in a brackish water RO element, compared to all commercial brackish water RO elements

The LD variant of these membranes using LD Technology® are available in 4” (CPA7-LD-4040) and 8” (CPA7-LD) diameters. The CPA7 MAX membrane has an active membrane surface area of 440 ft2 (40.9 m2) which reduces capital costs by requiring fewer pressure vessels and lesser floor space.

CPA7 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

CPA7 Applications:

• Boiler makeup water for power generation
• Industrial waste water recovery
• Zero Liquid Discharge (ZLD) / HERO process
• Ultrapure water for semiconductor manufacturing
• Ultrapure water for pharmaceutical industries
