CPA5-LD Series – New technology minimizing bio-fouling and colloidal fouling and enhancing cleanability. Where ultrahigh purity water is required under difficult feedwater conditions, the CPA5-LD gives the most desirable combination of high rejection and high flow. For industries such as power, semiconductor, food and beverage, where high purity water is critical to operations, CPA5-LD gives you the most desirable combination of performance and efficiency. CPA5-LD helps reduce RO system power consumption and the membrane resistance to biological and colloidal fouling helps reduce the number of cleanings required, lowering the overall cost of your operation.

LFC-3-LD Membrane Elements with Hydranautics LD Technology™ innovative low-fouling membranes combine the attributes of a neutrally charged surface with hydrophilicity to achieve the lowest organic and colloidal fouling in the most demanding Feedwater conditions. Hydranautics LFC3-LD membrane elements are designed with a thicker brine spacer lowering the Delta P meeting the increased demand for lower fouling membranes that require less frequent cleanings while maintaining a high permeate flow.

Please see the product specification sheets for the test conditions under which the stated performance is based, and the exact membrane element dimensions. Superior membrane technology is the key to Hydranautics’ innovative LFC (Low Fouling Composite) membranes. LFC3-LD membranes offer breakthrough technology in the treatment of difficult feedwaters and municipal wastewaters. Until now, these applications required significant pretreatment prior to being subjected to a composite polyamide membrane, which is eliminated with the use of the LFC3-LD membrane.
