Hydranautics BW CPA2 4040 Membrane

Hydranautics BW CPA2 is the second generation CPA high rejection brackish water RO membrane introduced in the early 1990’s. CPA2 membrane is available in diameters of 4” x 4 inches length and 99.7% rejection remains popular today as a robust work-horse product for Hydranautics. CPA2 4040 element is popularly used in the treatment of brackish waters to produce low TDS permeate.

  • 99.7% nominal rejection
  • High TOC, silica and hardness rejection
  • Permeate Flow: 2,250 gpd (8.5 m3/d)

Description

Hydranautics membranes are used to treat a wide range of highly variable waters as either primary treatment or as pre-treatment to reverse osmosis (RO) and nanofiltration (NF).
CPA (Composite Polyamide) elements set the standard for RO membrane elements – over 600 million gallons per day of pure water are produced by CPA elements for global municipalities and industries.

Water is essential for the existence of humankind. It is largely available on the earth, yet safe and potable water is scarce in many areas. Water does not provide any calories, but it’s still crucial for each living being, be it human, animal, or even plants. In places that lack the source of potable water, seawater and brackish water go through desalination and filtration to provide drinking water. And that’s when the Hydranautics membrane comes into the picture.

Basics of desalination and reverse osmosis

Desalination refers to a process of removing excess salts from brackish water and makes it safe and potable for domestic purposes. Reverse osmosis is the most prevalent method of desalination of brackish and seawater. The pure water obtained after the desalination can get used for human consumption, commercial and industrial applications, etc.

In recent years, there has been rapid growth in the number of desalination plants worldwide. Two primary motivators are causing the growth in desalination plants. They are:-  (a) Increased demand for potable water due to the unavailability of reliable water sources. (b) Cost-efficiency of RO membrane desalination.

Reverse osmosis or RO is a treatment technology that applies pressure to pass source water through the membrane and thus, separating contaminants from the water. RO works by reversing the natural osmosis process. Water has a natural tendency to pass through the membrane from low to high salt density.

RO system uses a pump to generate pressure; then, it forces the water with all its contaminants to pass through a highly sophisticated semi-permeable membrane designed by Hydranautics. It removes a significant amount of impurities from the water, and you get purified water as a result.

Why is Hydranautics BW CPA2 4040 membrane right for you?
