fibre in air filtration

Basin Water Inc has announced that it will begin to offer NSF 61 certified photocatalytic membrane systems to drinking water providers in the USA through its agreement with Purifics ES Inc.

Known as Photo-CatT, the technology combines chemical-free advanced oxidation process technologies with long-life UV and maintenance-free ceramic membranes in a single unit operation. Photo-CatT may be used alone or in combination with other treatment systems, and can effectively treat a range of organic contaminants in groundwater, including 1,4-dioxane, methyl tertiary butyl ether and pharmaceuticals and personal care products. Basin Water Inc says it is the only system of its kind with NSF 61 certification.

Reliant Energy has selected Siemens Water Technologies to provide a system to treat wastewater from a Flue Gas Desulfurization scrubber being constructed at the Keystone Generating Station in Pennsylvania, USA.

The wastewater system will include storage tanks, reaction tanks, chemical feed systems, a clarifier, gravity sand filters, and belt filter presses. The wastewater treatment system will de-saturate the wastewater and remove suspended solids and heavy metals from the scrubber waste stream so the water can be safely discharged.

The project is scheduled to begin operation in 2009.

Donaldson Company has developed the Pulse Jet Air Cleaning (PJACT) UltraT air cleaner.The company says the self-cleaning air filter is designed for maximum engine protection, minimised filter element servicing, improved fuel economy and vehicle engine power. The filter is designed for use in military vehicles and applications operating in demanding environmental conditions.

The PJAC cleans filter elements with short duration pulses of compressed air. According to Donaldson, this two-stage air filtration technology ensures engine protection and a longer life cycle due to minimised filtration servicing with no scavenge required.

ANSYS Inc has released version 4.0 of its FLUENT® for CATIA® V5 rapid flow modeling software. The company says this new product will provide computational fluid dynamics (CFD) technology to engineers working with Dassault Systèmes CATIA V5 software.

This release of FLUENT for CATIA V5 adds important new physics models to its analysis capabilities that ANSYS says will extend the types of products for which performance optimisation is possible. The technology can be used with a range of computer-aided design (CAD) or product lifecycle management (PLM) packages.

DuPont has announced the global availability of its Hybrid Membrane Technology (HMT) fibre in air filtration bag applications for industrial and commercial manufacturing. The product rollout has begun in the United States and Europe with availability through DuPont's laminator network.

Referred to in the industry as ‘dust collection bags',these filtration products are used with exit air to capture particles so they are not emitted to the environment.The incumbent polyester felt bags are commonly used at any production facility that generates particulates and dust from wood, cement, asphalt, paint, minerals and powders.
