MARKET PROSPECTS Membrane bioreactors (MBR) are used to purify wastewater where the distance to the city wastewater treatment plant is high.
ProSep wins C$3.5mn order for produced water treatment package
roSep Inc has secured a C$3.5 million contract from an international oil and gas company to supply a produced water treatment package for an onshore natural gas processing plant in Southern Asia. The ProSep solution consists of an induced gas flotation unit (IGFU), corrugated plate interceptor (CPI), nutshell filter and chemical injection package. This solution is designed to deliver high efficiency removal of oil and solids with a separation efficiency of up to 99.5% and 98% respectively, allowing the customer to meet strict operating specifications.
De.Mem builds its first overseas water treatment plant in Vietnam
anyang Technological University (NTU) start-up De.Mem Pte Ltd has launched its first overseas water treatment plant in Vietnam. Located at Duc Hoa, in Long An province near Ho Chi Minh City, the new 120 sq m plant has an output of 1 million litres of drinking water per day. The remote-monitored plant requires just one person to operate, and will be linked wirelessly via an NTU-designed network back to De.Mem’s Singapore office, which will oversee and manage its daily operations. The new plant, a joint venture between De.Mem and Vietnamese company GD Wasser, is backed by Singapore-based investment firm and Nanostart holding New Asia Investments which has invested S$300 000 in De.Mem. De.Mem (Decentralised Membranes), a subsidiary and partner of NTU spin-off company MINT (Membrane Instruments
& Technology), uses MINT’s patented membrane integrity sensor technologies developed at NTU’s Nanyang Environment and Water Research Institute (NEWRI). Andreas Kroell, partner, New Asia Investments, said that MINT’s new model is very appropriate for developing countries such as Vietnam, as it reduces costs for communities and companies, while supplying better quality water. “Our investment in De.mem and GD Wasser meets a strong market need for modern, but cost-efficient de-centralized water treatment technologies in SE Asia,” said Kroell. “The synergies with the know-how of MINT and the leading expertise of NTU in this space provide an excellent basis for further expansion of the business model.” GD Wasser, a joint venture between New Asia Investments Pte Ltd (30%), De.mem Pte Ltd (40%) and Glacier SG Pte Ltd (30%), operates mainly on a Build-OwnOperate (BOO) model providing clean water to its municipal and industrial clients.
Impregilo secures US river tunnel contract
mpregilo, in association with Parsons Corp, is to design and build a section of a rainfall and wastewater collection and treatment system in Washington DC. Impregilo will operate as the project’s leader and will coordinate the work with Parsons and its US subsidiary Healy, a specialist in underground projects. The Anacostia River Tunnel project involves the construction of a hydraulic tunnel that will run mainly under the Anacostia River, a tributary of the Potomac. The tunnel will collect and convey separately wastewater and rainfall.
New GE membrane purifies tough-to-treat wastewater
E has introduced a new membrane, the AG LF series, which can purify tough-to-treat water such as wastewater from industrial processes.
GE’s new technology is a low-fouling reverse osmosis (RO) membrane that resists degradation from water containing bacteria, colloids and other materials that foul and shorten membrane element life. GE has successfully pilot tested the new, low-fouling RO membrane in Asia. Customer experience with the AG LF membrane has shown the membranes require fewer cleaning cycles compared to conventional brackish membranes in tough-to-treat applications, such as steel production, power plants and plating processes. The new low-fouling membrane can reduce the time between cleanings by up to 50%, although actual results will vary with specific application conditions.
Marine market to grow significantly
arine vessels are purchasing air and liquid flow control and treatment equipment at an accelerating rate due to new limits on both emissions to the atmosphere and to water. This is the conclusion reached in the McIlvaine Co report Air/Gas/Water/Fluid Treatment and Control: World Markets. New rules and standards for ballast water discharge could impact nearly 70 000 ships which use international ports. The average cost of treatment systems to kill invasive organisms can range from as little as US$300 000 to more than US$3 million. A number of companies are already generating substantial revenues in this market. Alfa Laval, for example, just announced a SEK50 million order from a Korean ship builder. Severn Trent has now sold 18 systems, while Calgon Carbon has also emerged as a major participant in this market. Cruise ships are opting for advanced treatment of sewage. Several membrane bio reactor (MBR) suppliers such as GE and Hamworthy (Wartsila) have been selling systems for ships since 2002. This market includes new ships but also retrofits. Pumps and valves are integral to the ballast water and sewage treatment. They are also needed for the stack gas scrubbing systems, engine lubrication and for cargo transport on tankers.
