When not working with sludge from Melbourne's sewers, La Trobe University scientist Elizabeth Mathews is busy thinking about it. In partnership with Western Water, her research is designed to further the understanding of the processes that lead to sewer corrosion in order to ultimately further progress towards a solution.
In order to prevent corrosion of assets in wastewater treatment plants, Rhino Linings Australasia provides protective coatings which are strong, flexible and resistant to chemical attack.
Australian dairy ingredient processor Burra Foods recently installed a Hydroflux HyDAF Dissolved Air Flotation (DAF) unit for primary wastewater treatment and successfully halved its energy costs.
A wastewater treatment plant in the US has used a dynamic imaging particle analysis system to monitor the condition and presence of methanogens in its anaerobic digestion process to find a potential correlation with methane production.
The Andzac Aerator, from Andzac Water Treatment, recently underwent independent testing at Goulburn Valley Water's wastewater management facility in Tatura, country Victoria. The product's venturi air-injection design provides a system that can provide efficient and economical surface aeration for wastewater treatment ponds and other bodies of water.
A single DAF (dissolved air floatation) pump is said to be able to replace the entire air bubble system on DAF plants, according to pump supplier Hydro Innovations.
The FlowCAM imaging particle analysis system is a tool for detecting, identifying and quantifying algae or problem particulate matter in water treatment processes.
Calix's ACTI-Mag SP60 is a concentrated, controlled-viscosity, concentrated, stabilised suspension of magnesium hydroxide (MgO). The product is hydrated from Calix reactive MgO, imparting a good neutralisation capability due to the high surface area.
Engineers from Jhostoblak Corporate in Mexico have created technology to recover and purify seawater or wastewater, regardless of the amount of pollutants and microorganisms, in just 2.5 minutes.
AirPrex technology, by German group CNP, provides a struvite removal and biosolids enhancement process. It removes struvite (magnesium ammonium phosphate) from anaerobically digested sludge streams, thus eliminating potential pipe blockages and mechanical issues without increasing chemical use.
The UV disinfection industry has experienced tremendous growth over the last 25 years - particularly in Europe, the USA and South-East Asia. The development of new UV technologies over this period is a perfect example of an industry investing to meet market demand - in this case, demand for an effective, low-cost and environmentally friendly way to disinfect wastewater for re-use.
Furphy Engineering has introduced the Robotic Tank Inspection Technology, which is claimed to increase safety, reduce risk and improve the accuracy of tank inspections.
The Hydrothane ultrahigh-rate anaerobic process takes organic content within wastewater and generates green energy.
