Self-Cleaning Water Filter Lowers Water Treatment Costs, Uses Less Energy

Spiral Water Filter

Spiral Water FilterSpiral Water Technologies will showcase its self-cleaning water treatment filter, designed to address the challenges of difficult-to-treat waters, at Aquatech Amsterdam.

The company says its Spiral Water Automatic Self Cleaning Filter system provides 10 to 100 micron filtration and offers industrial, municipal and marine customers a water treatment system for their primary, pre-filtration or post-filtration applications.

Each filter contains a motor-driven spiral shaped brush that continuously cleans collected debris from inside the filter element. Solids collected at the end of the filter housing may be expelled through an automatic purge valve. The system does not require high pressures to operate, and it performs at very low differential pressure (>1 psi).

No backwash, crossflow or booster pumps are required, the company says. The filter can achieve continuous, fine filtration even in ultra-high and variable total suspended solids up to 25,000 ppm.

Spiral Water CEO Ashwin Gulati says the Spiral Water can filter up to 100 times dirtier water than traditional automatic filters while using only 10 percent of the energy required by existing systems. “This results in lower CAPEX and OPEX while achieving 99.9 percent water recovery,” Gulati says.

Spiral Water offers two high solids water filtration skids with its next generation Model 810 automatic, self-cleaning filter. The FS1 and FS2 skids — with one and two Model 810 filters respectively — have been designed to address the problem of high and variable suspended solids removal found in multiple industries around the world. FS1 and FS2 Skids remove ultra-high and variable TSS of up to 25,000 mg/L, as well as oil and grease, with no backwash or crossflow.

Target applications include industrial waste and process water, oil and gas produced water, industrial water, desalination, industrial wastewater reuse and recycling, marine and ballast water, mining, power generation and hydro power, food and beverage, and pretreatment for MF/UF/RO.
