Duraflow, a leader in the design, engineering, and manufacture of tubular membrane filters, introduces new models featuring increased surface area.
The Duraflow tubular membranes can be operated as a stand-alone system for stringent effluent compliance or in tandem with RO for water recycle/ZLD applications. The Duraflow tubular filter features high-flux (500-1000 GFD), 0.1 micron PVDF membrane with high TSS tolerance and chemical resistance.
Systems that have been running at or near capacity, changing to higher flow modules delivers additional capacity. For example, a 180 GPM system can be upgraded to a 300 GPM system (40% increase) simply by replacing 10-tube modules with 14-tube modules without requiring any additional floor space.
A unique advantage of the Duraflow modules is the structural strength of the tube material allowing for connection of more membrane modules in series. The more modules run in series the less energy required per gallon of purified water produced. Energy consumption can be reduced by 30% compared to a conventional design.
The combination of longer trains and more tubes per train produces flows and efficiencies comparable to or better than modules made with smaller diameter tubes. The capital cost per gallon of treated water lessens as the needed flow increases.
