The membranes are used in both process separation and water stream recovery. Membranes that treat the process streams add value in various ways including: purifying and concentrating valuable products, isolating valuable by-products, and recovering, reusing important fluid materials. Membranes that treat influent water sources prepare the water for any usage within the industrial process for dissolving, mixing, diluting, rinsing, quenching, cooling or in the utilities, for boilers and cooling tower feed.
Membranes are also used to treat wastewater to enable water reuse in the facility or to meet effluent discharge requirements.
DOWTM Membranes
DOW™ Specialty Membranes XUS120308 and XUS120304 High Temperature RO Element :
Features :
• High Temperature Reverse Osmosis Elements offer up to 80°C continuous operating temperature
• Robust DOW FILMTEC™ SW30 based reverse osmosis (RO) membrane sheet
• Improved safety and faster loading and unloading of elements from a system due to the rigid HYPERSHELL™ case, which doesn’t expand over time
• DOW HYPERSHELL™ technology, a machined polypropylene rigid outer shell, offers significant advantages versus standard mesh wrapped elements like minimizing channeling, improving the hydrodynamics of the element, which can result in energy savings and improved processing and Clean In Place (CIP) efficiency.
• Minimized channeling and control of premature element failures throughout product lifetime
• Easy and permanent identification due to laser etched model names and serial numbers.
• The 48 mil parallel feed spacer lessens the impact of fouling, reduces the pressure drop across the pressure vessel and enhances cleaning effectiveness.
• Ideally suited for various kinds of hot industrial streams with high demand of solute rejection. Typical applications are: Hot evaporator condensate reuse for process and rinsing purposes, Concentration of thin juice sugars or components in chemical processing and Production of water for the pharmaceutical industry.
