System converted seawater to drinking water while municipal system was rebuilt
A Pall Corp. mobile water treatment system produced clean drinking water for New Zealand communities damaged by the recent earthquake. The filtration equipment, owned and operated by the New Zealand military, was deployed as part of its humanitarian efforts to convert drinking water from seawater for residents of Brighton, Lyttleton and Christchurch after the 6.3-magnitude earthquake disrupted the municipal water system. A Pall WTS40 system provided 10,500 gal of water per day for area residents.
The WTS40 system is capable of producing drinking water from almost any raw water source within hours after delivery. Using state-of-the-art hollow fiber and reverse osmosis membrane technologies, the systems desalinate seawater and transform it into water that is free from harmful bacteria, cysts, and particles. Requiring minimal manpower for operation and maintenance, they enable municipalities, military units and ships at sea to boost water production on a permanent or temporary basis.
“The WTS40 systems provided a reliable source of drinking water in Christchurch until the municipal infrastructure was rebuilt. The system has been utilized for emergency relief in other regions, and we are gratified to have helped the New Zealand Defence Force manage the disaster situation in Christchurch,” said Jim Western, president, Pall Aeropower. Pall has previously supplied mobile water treatment systems to the New Zealand military for use on naval vessels. This is their first application of the technology for land use.
The WTS40 system used in New Zealand incorporated Pall Aria microfiltration membranes for prefiltration and Disc Tube reverse osmosis membranes for desalination. Designed to NATO defense standard 00-35, the system is housed in two 10-ft ISO containers and is shock and vibration qualified for transportation by land, sea or air.
