Dow Water & Process Solutions has introduced DOW FILMTEC ECO Reverse Osmosis (RO) elements.
Dow Water & Process Solutions says that it has focused its research on energy efficiency in current RO membranes and found that through configurational energy and element design, further energy savings could be realised. The new FILMTEC ECO elements combine new membrane chemistry and low dP feed spacers to help deliver notably lower energy costs and reduced chemical consumption when RO is followed by a mixed bed ion exchange unit.
Offering good rejection and low energy consumption (99.7% at 150 psi), FILMTEC ECO elements are intended to deliver up to 40% lower salt passage at up to 30% less energy when compared to standard RO elements. FILMTEC ECO elements are offered in ECO-400i and ECO-440i configurations to match reverse osmosis needs on a broad spectrum.
FILMTEC ECO elements have the ability to achieve:
• Improved uptime and reduced chemical use for utility providers;
• Increased rejection at lower feed pressure to accommodate purity needs for electronics manufacturing;
• Savings on energy use and chemical use and increased capacity by improving uptime in the beer and beverage industry;
• Reliable, energy efficient operations with the long-lasting performance required in mobile field location units.
