The NANO-SW nanofiltration membrane product line is primarily used in the oil and gas industry. These membranes are high-performance nanofiltration membranes which are able to selectively remove sulfate, thereby reducing the risks of scaling and reservoir souring when seawater is injected into the oil containing reservoirs for secondary oil production in offshore production. The membrane rejects 99.8% of sulfate while passing other ions, particularly monovalent ions such as chloride and sodium, allowing for ultra-low-pressure operations. They use patented Low Differential LD™ technology designed to minimize colloidal fouling. NANO-SW membranes use a patented 34 mil thickness feed spacer that prevents colloidal fouling and increases the effectiveness of membrane cleaning – resulting in lower differential pressure. As a result, the NANO-SW membrane does not need to be cleaned frequently – thus reducing treatment cost – while offering extreme durability and consistent performance. NANO-SW membrane is globally acclaimed for high sulfate rejection characteristics in oil and gas seawater injection applications. It significantly reduces operating costs and provides optimum hardness rejection in softening applications.
