Cloth media filter
Aqua-Aerobic Systems has introduced the latest addition to its line of cloth media filter systems - the AquaDiamond®. The shape and design of this filter allows users to take advantage of the inherent characteristics of cloth media technology with the added benefit of treating three times the flow capacity of a traveling bridge filter with an equivalent footprint. This product uses PA-13 pile cloth as its filter media. The pile cloth is constructed of nylon fiber material which removes very fine particulate matter and requires less cleaning energy than other filtration media.

Duplex bag filters
Hayward Filtration Duoline Bag Filters are designed for water and wastewater treatment filtration applications that cannot be shut down for filter bag change-out. The bag filters consist of two, double length size, single bag filter housings linked together with a special ball valve or butterfly valve flow switching system. When the bag in one filter housing requires changing, the flow can be diverted to the other housing by opening and closing the valves.
GreensandPlus from Inversand is an exact substitute for Manganese Greensand. It is resistant to attrition from high differential pressure and works well in water low in silica, dissolved solids and total hardness as well as in water over 70 degrees F without any degradation. The filtration process removes iron, manganese, arsenic, radium and hydrogen sulfide in municipal applications.
Parkson has announced a technological breakthrough in the design of its membrane bioreactor (MBR) system. The DynaLift MBR system features a membrane component that is located outside of the biological reactor, at the most convenient and accessible site nearby. These remote “airlift-assisted tubular membranes” make the system highly flexible. By separating the biological and membrane systems, each process can be independently optimized, allowing both systems to perform at peak.

GE Infrastructure, Water & Process Technologies, offers its Membrane BioReactor (MBR) systems. The systems replace the sedimentation process used in conventional wastewater treatment by removing the suspended materials with a microfiltration (MF) membrane. The membranes are submerged in an aeration tank, with the water being drawn through the membranes under vacuum, leaving the suspended biomass material in the aeration tank.

Amiad Filtration Systems recently unveiled its next generation thread technology. The new product is the MT-44, a 200 gpm, 3 micron, automatic, self-cleaning, string-wound cartridge filter. It was developed using the same thread, plastic material and overall dimensions of the previous cassette. However, this release is made of a stronger construction and a denser thread stacking, which has reduced the diameter of the pores and improved its filtration capabilities. The permanent cassettes, located inside the filter, are wound with many tight, multiple layers of high strength polyester threads serving as surface strainers and in-depth filters and accommodating operating pressure ranges from 3-150 psi.
