Screen filters

Forsta Filters' new FRP Series self-cleaning screen filters provide corrosion resistance in brackish, brine and seawater filtration applications. All wetted components are constructed from seawater-resistant plastic and high alloy materials. The filters can withstand pressures up to 150 psi. They are available with an on-line, or in-line flange configuration to accommodate simple installation. Their two-stage screening process includes a coarse screen responsible for straining out large debris and a fine screen to the designated micron rating.

Membrane system

The AquaMB Process® multiple barrier membrane system uses true batch biological treatment with cloth media filtration and external ultra-filtration membranes to provide enhanced biological nutrient removal, and virus and bacteria removal for reuse applications. The system offers flexibility and easily adapts to changing influent characteristics and future effluent objectives. Integration of the IntelliPro® process monitoring and control system can optimize plant performance with continuous monitoring, trending, data analysis and proactive operator guidance, further reducing energy and operations cost.

Ultrafiltration membrane

Kruger's Xtream Ultrafiltration membrane system is ideal for multiple applications such as reuse water production, phosphorus removal, and drinking water production. With a maximum membrane pore diameter of 0.03 μm, effluent phosphorus of <0.03 mg/L and effluent turbidity <0.1 NTU are regularly achieved. For drinking water, the membranes provide 99.99% removal of bacteria including cryptosporidium and giardia, as well as reductions in organics and disinfection byproduct precursors.

Cartridge filters

Gore has introduced a new generation of PTFE membranes in HDPE cartridge filters. The filters feature the company's latest ePTFE (expanded polytetrafluoroethylene) membrane technology that provides improved combinations of retention and flow performance. All non-PTFE components use HDPE to ensure low organic and metal ion extractables.

Seawater RO

NanoH2O has added a new seawater reverse osmosis (SWRO) membrane to its high flux, high rejection QuantumFlux product line. This new SWRO membrane, the Qfx SW 400 ES, features 400 square feet of active membrane area with a permeate flow rate of 13,700 gpd. The membrane was recently awarded NSF Standard 61 Certification, attesting to the viability of thin-film nanocomposite (TFN) membranes when used for the production of potable water.

Membrane bioreactor

MeurerMBR, a back-pulsable flexible flat-sheet membrane bioreactor, has been certified to produce effluent suitable for reuse, in compliance with the California Water Recycling Criteria, Title 22. Certification was completed under the product's original name, MRI BIO-Cel® MBR. Equipped with the new chemical-free Mechanical Cleaning Process (MCP), the MBR outperformed Title 22 requirements in all areas, with filtrate turbidity not exceeding 0.1 NTU, and a 4.0-log removal of virus at the 50th percentile.
