Automatic self-cleaning filter works with proprietary sensor technology to measure the buildup of solids electronically and automatically activate the valve to purge them. The automatic filtration technology allows one-pass, low micron filtration without backwash or crossflow. The high and variable solids are automatically concentrated and purged in the process. This allows solids recovery and management, and the volume of diluted wastewater is reduced. The Spiral Water system offers a reduction in CapEx and OpEx for companies using centrifuges and other dewatering systems. Market applications include oil and gas produced water; industrial water; desalination; wastewater reuse and recycling; power generation and hydro power; food and beverage manufacturing; biodiesel/biofuels; and pretreatment for microfiltration, ultrafiltration and reverse osmosis.
