SWC5LD Seawater Membranes Dutcotennant

Dutco Tennant brings a range of Sea Water Composite Reverse Osmosis membranes in order to meet the demands of the Gulf Countries which mainly rely on desalination for water requirements. Depending on the desired product, there is a range of Sea Water Membranes that Dutco Tennant offers. Each of these Sea Water Range of RO Membranes is applicable to certain feed water and system and most are produced for our clients to receive the highest productivity and salt rejection.

SWC5 range of RO Membranes from Hydranautics has the optimum salt rejection rate and permeate flows. Chosen according to lower permeate TDS and the required lower feed pressure. Highest energy efficiency at the lowest cost is offered by SWC5 membranes and they are used in big desalination plants. In two different types of variants, which are the LD and MAX, the SWC5 membranes are available.

Low differential LD Technology models are offered to minimize colloidal fouling when used with conventional pre-treatment equipment. They offer consistently low feed pressures and the highest duration between two successive cleanings.

The MAX models have a 440 ft2 (40.9 m2) active membrane surface area. They provide excellent performance with high TDS and boron removal from warm waters.

The Reverse Osmosis water filtration technology Membrane by Hydranautics (Nitto) is designed for Seawater / High Salinity Water applications that require a psi of 800. This Membrane uses Reverse Osmosis water filtration technology to take out 99.80% of contaminants found in the feedwater, which makes it best suited for seawater desalination and high TDS industrial wastewater treatment applications, including conventional and hybrid designs.

Depending on the system there are available membranes in 2 different sizes: 4” and 8” are available.

Hydranautics membrane supplied by Dutco comes from either Japan/USA. The Reverse Osmosis water filtration technology Membrane SWC5 RO Membrane is Spiral Wound Composite Polyamide. The advantages in using the Hydranautics (Nitto) SWC5RO Membrane are each membrane offers the highest productivity and salt rejection rates in the industry combined with the optimized flow, low fouling, and low energy consumption and does not need to be cleaned frequently thus reducing treatment cost while offering extreme durability and consistent performance.

Dutco has years of experience in dealing with seawater reverse osmosis filtration membranes which are important to make sure that the water that you are getting is up to the standard of the local municipality and as well as satisfactory for the application whether it’s for seawater, brackish water or greywater.

Our group of technical people are knowledgeable and trained to design the best suitable solution or method in which the system will best cater to your requirement as well as to make sure that systems will be installed, commissioned, and run at optimum conditions.
