New Zealand's dairy industry takes action against water waste
31 May, 2007New Zealand's leading dairy cooperative, Fonterra has announced a new environmental policy that introduces tough measures against farmers who don't comply with environment standards in the management of effluent, with the ultimate sanction of not collecting farm milk.
Treating organic wastewater
02 May, 2007EBCRC researchers at the South Australian Research and Development Institute (SARDI) have developed a process where high-strength wastewater is turned into valuable products
Sewer technology
22 September, 2006Becker products are used in the construction of vacuum sewer collection systems. They can be used as an alternative to gravity systems as they do not rely on the natural gradient for the transportation of sewerage. They offer an odour-free environment, with the ability to transport effluent uphill, and use less water for flushing.
On-site sewage system danger
19 April, 2006Installing on-site sewage systems in the wrong soil types can lead to potential environmental and health hazards, a Queensland University of Technology researcher has warned.
Wastewater treatment system
21 March, 2006The Kele Effluent Wastewater Treatment System (KEWT) was developed by Ben Kele during the course of his Master's study at the Central Queensland University. The system is a recirculating on-site wastewater treatment and effluent reuse technology. The wastewater undergoes primary treatment and is then further treated through a lined sub-surface recirculating filter combined with an evapotranspiration area. The mixture of filter materials can be adapted to suit the treatment requirements; the most commonly used components are sand, blue metal, river rock, zeolite, scoria and charcoal.
Wastewater lagoon bio-remediation
21 March, 2006Byogon PX-109 is a special extract of plant material and 100% organic. Developed by the University of Hawaii as a bio-stimulant it is designed to enhance cell growth. It is an alkaloid that acts to increase cellular metabolism of a wide variety of naturally occurring microorganisms. When combined in wastewater streams it releases Xeronine to re-invigorate existing bacteria in sewage to reduce odour, greases, and improve water quality.
Upgrading a wastewater treatment plant
03 January, 2006Cost-effective engineering has enabled the City of Poteau, Oklahoma to achieve major savings while undertaking recent upgrades to municipal wastewater treatment facilities
Wastewater conversion system
26 July, 2005The H20 Pureplus system uses no chemicals, no complicated components and converts wastewater to clean water at a potable standard.
Oily water separator
24 June, 2005RWO's Oily Water Separator is capable of handling emulsions and also has applications for land-based wastewater treatment plants. It is capable of reducing the oil content to less than 15 ppm and in extreme cases to less than 5 ppm.
Grant to purify wastewater
03 May, 2005The Biotechnology Research Centre at La Trobe University, Bendigo has started a three-year project to develop and evaluate a new process to purify wastewater
