WATER FEBRUARY 2013 98 Water Business CONTINENTAL WATER MEMBRANE SYSTEMS OFFER ADVANCED, EFFECTIVE WATER PURIFICATION Reverse osmosis technologies have extensive industry, science and community uses, while ultra ltration technologies bring new ef ciencies to many complementary processes. As water becomes an increasingly precious community and industrial resource, demand is growing for membrane technologies as a cost-effective option to deliver a large range of puri cation and separation needs. Reverse osmosis and ultra ltration membrane systems from Continental Water provide ef cient and easy-to operate ltration processes for applications such as production of drinking and process water, industrial processes, wastewater treatment, sewage treatment, product recovery, groundwater treatment and agricultural waste streams. "Membranes for water applications are a constantly evolving technology," says Continental Water Managing Director Mr John Winstanley. "Extensive research is being invested in this arena and innovations are being made all the time to enhance the end quality of water treatment. "Many of the technologies' general bene ts are well known -- such as energy ef ciency and high puri cation ef ciencies -- but new answers are constantly emerging to speci c industry issues and these are the advances of which users need to be aware. "An ef cient reverse osmosis system is able to remove a broad spectrum of impurities from water. Applications are available which provide high recovery and energy ef cient features. Ultra ltration systems, meanwhile, eliminate the need for clari ers and multimedia lters for waste streams, enabling them to meet critical discharge criteria or to be further processed by wastewater recovery systems." Reverse osmosis removes many types of large molecules and ions from solutions by applying pressure to the solution when it is on one side of a membrane. The result is that the solute is retained on the pressurised side of the membrane and the pure solvent is allowed to pass to the other side. The technology effectively removes organics, inorganics and micro-organics by approximately 98%. Pre- and post- ltration systems are also available to enhance the quality of the feed water to the systems and polish the water after the reverse osmosis system. A reverse osmosis system is able to remove and reject a broad spectrum of impurities from water with minimal energy use because it requires only mains water pressure and no chemicals, according to Mr Winstanley. Reverse osmosis membranes used to reduce salt levels from bore and river water achieve up to 99.5% ef ciencies to produce the highest quality permeate. Applications include desalination treatments, water and wastewater applications, pump water (levels 1--3 for laboratories), drinking water puri cation and the food and beverage industry. Continental Water Reverse Osmosis Systems feature: • RO high-quality membrane modules • High pressure and CIP pumps • CIP tank • Process pressure gauges and ow metres • Skid mounted pre- lters • Stainless steel frame • ABS pipe work and valves • PLC controlled with option of HMI, GSM, dialler or SCADA remote monitoring • Containerised or modular integration Continental Water's Ultra ltration system is fundamentally different from micro ltration and nano ltration, except in terms of the size of the molecules involved. "Ef cient ultra ltration systems utilise membranes which can be submerged, which are back- ushable, air-scoured and, as well, feature spiral-wound UF/MF membranes. They offer superior performance for the clari cation of wastewater and process water," said Mr Winstanley. Continental Water Ultra ltration Systems feature: • 8" x 60" high-quality hollow- bre membranes • Feed and back ush pumps • Control valves • Process pressure gauges and ow meters • Stainless steel frame • APVC and ABS pipe work and valves • PLC controlled with option of HMI, GSM dialler or SCADA remote monitoring • Containerised or modular integration For information about Continental Water products, please email Fiona.Arakelian@ continentalwater.com.au AIDS FOR FLOOD, PIPELINE AND DEWATERING WORK Versatile Pronal in atable lifting cushions and pipe stoppers from Air Springs Supply can be invaluable during installation, maintenance and dewatering operations. Especially in rugged, sometimes remote and particularly muddy or sandy locations, including areas affected by recent oods, it can be dif cult to provide crane access overhead for work on pipelines, or to obtain suf cient clearance and a rm foundation for pipeline lifts from beneath.
