$8.7m biogas recovery project to reduce meat producer's carbon bill
27 August, 2013JBS Australia, the country's largest producer of meat products, has engaged technical service company Wiley to project manage the $8.7 million upgrade of its wastewater treatment system.
Transpacific granted patent for grease-trap wastewater solution
16 August, 2013Transpacific Industries Group has been granted a patent for its innovative solution to reduce and re-use wastewater taken from grease traps. The company’s Thomastown Grease Trap Treatment Plant in Victoria has adopted a new process and mechanical device to screen, filter and separate wastewater components, allowing it to be treated and re-used.
Turning waste into power with anaerobic digestion
31 July, 2013Biogas can be burned directly in boilers for heat recovery and used for manufacturing, heating or cooling; this is the simplest method of direct biogas utilisation on site. Alternatively, it can be burned in engines to generate electric power (cogeneration). Combining hot water recovery with electricity generation, biogas can provide an overall conversion efficiency of 65-85%.
Pasteurisation disinfection using waste heat
12 July, 2013 by Lauren DavisPasteurisation - ie, the rapid heating and cooling of food (usually liquid) - has been used since the late 1800s to treat and disinfect milk. Now, a version of the process will be used in Australia for a different purpose - treating recycled water.
Cane processors profit with green energy and environmental benefits
12 July, 2013A producer of green energy from food and agribusiness wastewater is deploying advanced anaerobic technologies that achieve high returns of biogas from the world’s largest crop - sugar cane.
Urine recycling to extract precious nutrient
05 July, 2013The recycling of plastic bottles, paper and food at home is common across the world. But as many of the Earth’s resources become more scarce, chemical engineers are looking at new ways to recycle - including extracting precious nutrients such as phosphates from urine before it enters the sewage system.
Xylem Wedeco LBX 850e wastewater disinfection solution
17 June, 2013The Xylem WEDECO LBX 850e system is a closed-vessel, ultraviolet (UV) disinfection solution which has been optimised for large-scale wastewater treatment plants, industrial and water re-use applications.
CMAX wastewater filtration media
07 June, 2013The CMAX filtration media is a specialty adsorbent designed to remove surfactants, soaps and detergents in wastewater.
Pasteurisation to produce recycled water
04 June, 2013Pasteurisation - a process used worldwide to disinfect and treat milk - will soon be used to treat recycled water in a project initiated by the Australian Water Recycling Centre of Excellence (AWRCE).
Dealing with crap to improve water quality
03 June, 2013To better understand how bacteria impact the environment, a former University of California, Riverside graduate student spent nearly a year building a system that replicates a human colon, septic tank and groundwater and ‘fed’ the colon three times a day during weeklong experiments to simulate human eating.
Australia’s first Infrastructure Sustainability (IS) rating
15 May, 2013Tenix has been awarded Australia’s first ever Infrastructure Sustainability (IS) Design rating, achieving an ‘Excellent’ rating level for the design of two sewage treatment plants (STPs) at Cannonvale and Proserpine in North Queensland.
Water utility using sewage sludge to create energy
02 May, 2013In what is claimed will be an Australian first, Yarra Valley Water is developing an innovative waste-to-energy facility in the northern suburbs of Melbourne.
Mussel shells to treat polluted mining water
29 April, 2013University of Canterbury researchers are investigating an ecologically engineered treatment system to solve wastewater problems, such as acid mine drainage, on mining sites.
