Spiral Water Technologies, a developer of advanced filtration solutions for difficult-to-treat waters, has introduced the Model S1000 automatic self-cleaning filter for both process and wastewater streams.
Designed to remove ultra-high and variable total suspended solids (TSS) from difficult-to-treat fluids in industrial process and wastewater treatment applications, it is suited for use in such markets as food and beverage, power, chemicals, metals, and mining.
Model S1000 applications include:
- Fluid filtration and product recovery: Filtration of industrial and beverage products to remove suspended solids or recover high-value solids from process streams. Examples are wine and juice filtration, liquid fertiliser, and other industrial fluids.
- Bulk solids removal: Removal of solids from wastewater streams in the food and beverage, municipal wastewater, and other industries streams where suspended solids reduction is required for discharge or reuse. Examples are wash water in food and beverage processing and the reduction of organic matter in wastewater streams for TSS and BOD reduction.
- Equipment protection: Removal of suspended solids in process water or wastewater that would foul or destroy industrial process equipment. Examples include nozzle and heat exchanger protection.
“Given the strong market pull for our technology in the industrial and wastewater markets, we have invested in a robust stainless steel filter for high flow, high temperature, and high pressure applications,” said Ashwin Gulati, president and CEO of Spiral Water.
“We look forward to working with our customers and partners to provide an innovative and cost effective way to solve their filtration and product recovery needs.”
With a maximum flow rate of 1,360m3/d (250 gpm), the S1000 is designed for over three times the flow of Spiral Water’s Model 800 Series, the company’s initial product.
It can also operate at higher pressures up to 10.3 bar (150 psi) at 21°C, and at higher temperatures up to 105°C.
Spiral Water’s filtration technology differs from traditional automatic self-cleaning technologies in multiple ways, the company said.
Not only do the energy efficient units provide solids concentration, they are also capable of finer filtration and can filter up to 250 times dirtier water than traditional automatic self-cleaning filters while achieving up to 99% water recovery.
The units are also compact, modular, and scalable to meet each customer’s requirements.
Each filter unit contains a motor-driven, spiral-shaped brush that continuously cleans collected debris from inside the filter element.
Solids collect at the end of the filter housing to be expelled through an automatic purge valve or a continuous concentrate stream.
The system does not require high pressures to operate and performs at very low differential pressure, with no backwash, cross flow, or booster pumps required.
