DuragafTM Filter Bags from Eaton Filtration represent the latest development in needled felt filter bag media. They offer a service life two to five times greater than standard felt media filter bags. The bags are available in polypropylene and polyester. These two materials use a fiber blend with a finer fiber diameter and a higher weight than ordinary media.

Membrane filtration

Click here to enlarge image

Hydranautics’ Low Fouling Composite LFC3-LD (Low Differential pressure) membrane is designed with a thicker brine spacer, lowering the Delta P, meeting the increased demand for lower fouling membranes that require less frequent cleaning - while maintaining a high permeate flow. It can provide 11,000 gpd of flow at 99.7% nominal salt rejection. The membrane is well suited for the treatment of difficult feed waters for numerous municipal and industrial applications, which up to now required significant feed water pretreatment upstream of any composite reverse osmosis membrane.

Band screen

JWC Environmental’s Bandscreen MonsterTM, part of the Monster Separation SystemTM, screens wastewater to remove problem solids and provide protection for membrane bioreactors (MBRs). The unique inside-out flow pattern captures solids on the inside loop of the screen to prevent solids from bypassing, and the rotating perforated panels with 2mm openings lift unwanted solids out of the channel to prevent them from clogging MBRs. The stainless steel and UHMW plastic construction extends equipment life.

SpiraSep ultrafiltration technology from Ashbrook Simon-Hartley employs a hydrophilic sheet membrane configured in a spiral orientation. The spiral approach creates a structure that is durable, yet provides discrete, open feed channels. These open feed channels virtually eliminate plugging and make the membrane efficiently backflushable.

Titan MBRTM marries the wastewater treatment engineering expertise of Smith & Loveless with Flat-Plate Membranes. Submerged in the aeration section of the MBR tank, the S&L Flat-Plate Membrane - rated at the microfiltration level - maintains high permeability and flux rates even at peak-day rates. Because the system employs air scouring to prevent fouling, it does not require back-pulsing or the associated equipment and chemical costs typical of other systems.
