Cloth media filter

Aqua-Aerobic's new Aqua MegaDisk™ cloth media filter features 30% larger diameter disks than the original AquaDisk filter and the capability of treating up to 24 MGD in a single unit. This filter operates in 80% less space than sand filters with comparable hydraulic capacity and is an ideal solution for deep-bed sand filter retrofits.

Media filter

The Schreiber Fuzzy Filter is a high-rate, compressible media filter used for various industrial water and wastewater treatment streams. Through media compression, pore size is adjustable down to 4 microns. Footprint is minimal because of operation at flux rates of up to 44 gpm/ft2. Industrial applications include stormwater, membrane reject water, boiler feedwater, raw river water, cooling water, and wastewater. Vigorous air scouring of the uncompressed media bed, while backwashing with influent (no clean water used), cleans the media. After the wash cycle is complete, media is returned to its compressed state and filtration is resumed.

Reverse osmosis elements

DOW FILMTEC™ ECO elements offer rejection and flow performance for industrial water needs by using new membrane chemistry and low-dP feed spacers that deliver significantly lower energy costs and reduced chemical consumption in downstream polishing costs. With a new industry-leading performance rejection of 99.7% at 150 psi, the elements provide robust performance over a longer element life, which means less impact on the environment and less strain on the bottom line. DOW FILMTEC ECO elements are offered in ECO-400i, ECO-440i and ECO-500i configurations.

Ultrafiltration module

Membrana introduced the W20 Liqui-Flux® Ultrafiltration Module with 91 m2 of membrane surface area. This new product with its high filtration surface area allows customers to build ultrafiltration systems using fewer modules and less equipment. The module is a durable and robust ultrafiltration system that can process flow rates of 4.5-14 m3/h in a single device. Further, the module utilizes the proven UltraPESTM membrane in an inside-out flow configuration and delivers consistent, high-quality filtration. Many systems using Liqui-Flux® Ultrafiltration Modules are currently operating in process water and pre-treatment to RO applications around the world.
