Pentair says its latest electronic water-purification system can provide retail, car washes and laboratories with safe, soft, bottled-quality water, with 90 percent less wastewater than other systems.
The system, being previewed at the WQA Aquatech Show in Las Vegas, is built around a hybrid deionization process, using Pentair and Voltea technologies to combine the benefits of reverse osmosis filtration with those of a water softener – without requiring salt as a regenerant, the company says.
Voltea’s patented “stack” configuration of electrodes combined with ion-selective membranes forms the core of the system, Pentair says. Click here to see an animation explaining how the treatment process works.
Pentair will use the new system in products targeted at light commercial applications. Products featuring the filtration system should become available in mid-2012.
In June last year, Kraton Performance Polymers won an award from the Presidential Green Chemistry Challenge Awards for its reverse osmosis membranes for salt water purification. The Nexar family of halogen-free, high-flow polymer membranes are made using less solvent, allowing them to purify hundreds of times more water than traditional membranes, saving 70 percent on membrane costs and 50 percent on energy costs, the EPA says.
