Chromocult Coliform Agar established as a basis for new standard
NEWS Oman Power & Water Procurement Co (OPWP). Located 60 km (about 37 miles) north-west of Muscat, the plant will be capable of delivering 56 775-m3 (12.5-million gallon) of water per day and is part of a phase-two expansion of ACWA Power’s operations in Barka, where it already runs a plant delivering 136 660 m3 (3 million gallons) of water per day and 427 MW of power. Pretreatment will involve a coagulant dosage prior to filtration using Pall microfiltration (MF) membranes, and the high-pressure system will be equipped with Calder dual work exchange energy recovery devices (DWEER). Taking its feed from the cooling section of the existing MSF units, the Osmoflo plant’s MF pretreatment is followed by five SWRO trains. Serving the city of Muscat and surrounding areas, the plant will address the increasing water demands of the region, says the company. ‘This is an important project for us as it demonstrates the international capabilities of Osmoflo, and it reinforces our ongoing commitment to international growth by servicing the global market,’ explained Marc Fabig, Managing Director, Osmoflo. The system will be delivered in three phrases, the first of which is scheduled to be operational in August 2015. Contacts: Osmoflo Pty Ltd, 382 Diment Road, Burton, 5110, South Australia, Australia.

Water treatment platform is compact, flexible and configured easily
U
S filtration, separation and purification company Pall Corp recently introduced a packaged water treatment system called the Aria FIT which, it says, offers a flexible, configurable platform that enables it to suit even the most challenging space requirements. According to Pall, it extends its Aria AP platform’s long history of producing consistent and reliable high-quality water for both municipalities and industry. Pall Aria FIT water treatment systems are designed to produce drinking water that meets 6
Membrane Technology
strict purity standards around the world, and also provide clean process and wastewater for many industries. The systems use proprietary filtration modules to remove a wide range of contaminants from surface-water and groundwater sources. ‘Customers want and deserve a membrane system that does not require modification or compromise because of their needs,’ said Dave Lamphere, Global Water Portfolio Manager, Pall Process Systems. ‘Pall is happy to provide exactly that. Endusers benefit from the ability to custom-design a system to their unique specifications, and consulting engineers and contractors will appreciate the system’s simple water and electrical hook-ups, which ensure rapid system start-up and commissioning.’ The pre-engineered, factory-tested and preassembled skids ensure fast, problem-free installation and start-up. Smart diagnostics and an intuitive dashboard interface enable the system to be quickly learned and easily operated.
CCA, which has been available for more than ten years, is also approved by the US Environmental Protection Agency for detection and enumeration of E.coli and coliform bacteria in water. CCA is based on enzymatic reactions that distinctly colour the colonies of the target organisms. Its simultaneous detection of coliform bacteria and E. coli provides results earlier as well as easier laboratory procedures, and colony identification improves the testing of samples with low background flora, such as drinking water, disinfected pool water and finished water from drinking-water treatment plants – and, thus, helps to combat waterborne pathogens. EMD Millipore’s EZ-Pak membrane filters and Bactident Oxidase strips, which are used to confirm coliform bacteria, were included in the validation process.

MD Millipore, the life sciences division of Merck KgaA of Darmstadt, Germany, reports that its Chromocult Coliform Agar (CCA) has been used by the International Organization for Standardization (ISO) as the only suitable culture medium to develop a revised standard for enumerating coliform bacteria and E. coli in water samples – replacing Lactose TTC agar. The completely revised ISO 9308-1 standard came into effect on 16 September 2014. ‘Detection of potential pathogens in water is a critical function for a company to manage quality control microbiological workflow and essential for reducing the risk of contamination and ensuring consumer safety,’ said John Sweeney, Head of Lab Solutions, EMD Millipore. ‘We are proud that our Chromocult Coliform Agar is the only culture medium to meet the more stringent ISO 9308-1 requirements. It is a testament to expertise and leadership in microbial detection and commitment to offering the most innovative products.’ EMD Millipore’s CCA is available as a dehydrated culture medium and ready-to-use agar plate.
orvair Filtration Group has developed Stabifil, which is described as a novel polyphenol removal product that optimises beverage processes, lowers capital costs and offers fast flow-rates. According to the company, it also benefits from no loss of loose polyvinylpyrrolidone (PVPP) powder with its potential to create longterm maintenance, and health and safety issues. The product uses Porvair’s patented technology of co-sintering PVPP powder with Vyon porous plastic to effect product exposure to PVPP at high flow-rates with low contact time in a sanitary and highly efficient manner. The product also can be regenerated many times, says the firm. Stabifil, currently configured in cartridges to enables users to use it in standard cartridge housings, is undergoing production trials with leading beer and wine producers in Europe. Lenticular and other configurations are planned developments for larger producers.
