Spiral Water Technologies exhibited its Automatic Self Cleaning Filter and Solids Recovery System at Singapore International Water Week (SIWW).

The Spiral Water filter was developed to address the specific challenges of difficult waters. With its patented design and operation, the Spiral Water filter provides 10 to 100 micron filtration and offers industrial and municipal customers a solution for their primary, pre-filtration or post-filtration applications.

Spiral Water’s filtration technology, low energy use, small footprint and light weight result in lower CAPEX and OPEX while achieving 99.9% water recovery.

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 filter can achieve continuous fine filtration even in ultra-high and variable total suspended solidsup to 25,000 ppm.

Spiral Water’s solids recovery system integrates the company’s automatic self-cleaning filter with proprietary sensor technology that measures solids build-up electronically and automatically activates the valve to purge them. This enables easy solids and product recovery in industrial process streams, and the major reduction in diluted wastewater can significantly lower clean-up expenses.

In addition, the Spiral Water solids recovery system lowers CAPEX and OPEX for companies currently using centrifuges and other de-watering systems that are both expensive and inefficient in solids concentration. In recent demonstrations, Spiral Water converted the waste stream from less than 1% solids into 65% solids by volume, providing dramatic improvement in its solids management efficiency. For a fruit juice producer, Spiral Water was able to eliminate the costly centrifuge process, protect the flavor of the product and concentrate the nutrient rich byproduct into a potential resale commodity. 

Market applications for the Spiral Water filtration and solids recovery system include food and beverage manufacturing, oil and gas produced water, industrial water, desalination, wastewater reuse and recycling, marine and ballast water, mining, power generation and hydro power, biodiesel/biofuels, and pretreatment for microfiltration, ultrafiltration and reverse osmosis.
