FILMTEC seawater RO membranes are high quality reverse osmosis elements that provide high salt rejection and surface area to bring long-lasting cost-efficiency for marine desalination systems. These membranes offer high boron rejection to satisfy the world’s freshwater standard and provide high performance for the life-span of the operation without the use of post treatments. For this reason, Filmtec membranes are considered the most durable of its kind in the available market and are capable of being cleaned more easily than other reverse osmosis membranes.

Filmtec elements are manufactured to boost the productivity of systems at low pressures, and low to high cleaning energy. The enhanced membrane make-up diminishes the energy and pressure usage beneath any other existing seawater reverse osmosis membrane. Due to this benefit, operational costs and the risk of o-ring leakages which cause bad water quality are substantially reduced. Filmtec seawater membranes are highly productive elements that provide incredible durability and high-rejection to work properly in high fouling or contaminated feedwater. This will maintain an effective and smooth operation with low cost of water.

What is the Seawater Reverse Osmosis System?

The Seawater Reverse Osmosis (RO) is a process whereby the salt and mineral content of the water is filtered out to ensure the water is safe for drinking. This process involves pushing the seawater at high pressure through a semi-permeable membrane. Seawater desalination through reverse osmosis has been the most effective option for water purification and it involves four components known as Pretreatment, Pressurization, Membrane Separation, and Post-treatment Stabilization.

In Reverse Osmosis, the water molecules are pushed through a semi-permeable membrane. There’s a higher pressure applied here, compared to that required for osmosis to occur naturally. Using the RO in seawater purification helps pure water molecules pass through effortlessly while filtering out contaminants, including salts and suspended solids.

Benefits of the DOW FilmTec SW30HRLE-400 Seawater RO Membrane

The best and highly effective RO Membrane is capable of removing up to 99% of contaminants such as dissolved salts, particles, bacteria and other pathogens from the feed water. It also delivers high flux and energy efficiency to guarantee maximum water flow.

The DOW FilmTec SW30HRLE-400 Seawater RO Membrane is the Reverse Osmosis Membrane offers high boron and salt rejection with high performance in water purification. It is highly durable and can be cleaned more effectively than other RO elements.

The DOW FilmTec SW30HRLE-400 Seawater RO Membrane is one of the best products ideal for municipal, industrial and commercial applications, to produce safe water drinking and eventually health.
