CPA7-LD Hydranautics Nitto Membranes

Hydranautics CPA7-LD High Rejection Brackish Water RO Element

Product Description

The Hydranautics CPA7-LD (Composite Polyamide, $7\text{th}$ Generation, Low Differential Pressure) is an industry-leading $8 \text{ inch}$ diameter element engineered for applications demanding ultra-high purity water, such as power generation, pharmaceutical manufacturing, and the semiconductor industry. As the sixth generation of the CPA series, it delivers the highest combination of high rejection and flow capability for brackish water sources.

This element provides an exceptional nominal permeate flow of $11,500 \text{ Gallons Per Day (GPD)}$ with an outstanding stabilized salt rejection of $99.8\%$ (tested against $1,500 \text{ ppm NaCl}$ at $225 \text{ PSI}$ ). The CPA7-LD features an innovative $34 \text{ mil feed spacer}$ and patented LD Technology® to minimize colloidal and biological fouling, resulting in lower feed pressure requirements, longer cleaning intervals, and reduced operational costs.
