Electropositive pleated filters

Argonide has recently announced the development of the NanoCeram-LR™ (NCLR) high performance pleated filter cartridges specifically engineered and designed to replace lenticular filters. This pleated filter cartridge has a lower shipping weight per cartridge to help reduce shipping costs. And, since each NCLR holds less water, it eases the process of filter replacement for the operator. Each filter cartridge contains the company’s patented non-woven filter media matrix infused with nanoalumina fibers, creating an electropositively-charged depth filter. Argonide Corporation, Sanford, FL, 407-322-2500,

Self-cleaning filters

Forsta Filters has released its Green-Clean industrial filtration technology. Without interrupting system flow during backwash, the system uses smaller flush valves to minimize the volume of water required to remove buildup on a filter element by up to 70%. Using internal vacuum nozzles, the system scans and removes debris from the filter in 15 seconds or less. The company offers a full line of self-cleaning water filters (1-36” flange size), with screen elements ranging from 5 to 4000 micron. Forsta Filters Inc., Las Angeles, CA, 888-936-7782,

DBP, TOC reduction

The High Rate MIEX® System uses an advanced ion exchange process for the removal contaminants from water and wastewater streams and is most commonly used for the reduction of TOC, disinfection by-products, color, and nitrate. These systems have small footprints, very low waste volumes and are not subject to chromatographic peaking. The resin used in the process has a magnetic property that allows the resin beads to be retained in a fluidized bed at high hydraulic loading rates. The system can be used as a stand-alone treatment process or in combination with other processes to meet more than one treatment objective. can be achieved.
