A proposed national environmental standard to improve the environmental performance of domestic on-site wastewater systems is out for public comment, Environment Minister Trevor Mallard said.
BSI British Standards has published an amended version of BS 6297.
Vistech, the Victoria–Israel Science and Technology R&D Fund, is providing $970,000 for three new projects and is calling for more applications.
Australasian wastewater solutions group Contra-Shear Technology is expanding its industrial and municipal services and technologies from a new headquarters established in Sydney. The company has also changed its name to CST Wastewater Solutions to reflect its expanded scope as it moves to its combined office and warehouse in Roseville.
Exploiting the solid by-product of sewerage treatment and reducing the amount of waste added to landfill were two of the driving factors triggering a six-year nationally coordinated study into biosolids, the results of which will be highlighted at the Australian Water Associations Biosolids Specialty Conference on 11–12 June in Adelaide.
The Weir Self-Primer (WSP) is a rugged, dependable self-priming end suction centrifugal pump. The pump is suitable for a range of solids-handling jobs where a self-priming application is required. It is available in a 3, 4, 6, 8 or 10" suction/discharge.
Gas-emitting media in metering applications can often reduce pump output or even prevent the pumped medium from being delivered. To avoid this situation, the pumps generally need to be bled manually in such applications. This procedure can be performed simply, conveniently and safely by the delta diaphragm metering pump with the new venting module.
UniSA scientists have discovered a simple way to remove bacteria and other contaminants from water using tiny particles of pure silica coated with an active nano-material.
The FloPro Series 3 uses ultrasonic technology to measure water flows practically anywhere. Insertion probes can be used to measure flow in full pipes or strap-mounted sensors do the job in partially full pipes or channels, making it suitable for wastewater plants.
The Dimension 4i from LDS Test and Measurement is a data acquisition system that combines high-speed, gap-free data recording with real-time FFT analysis. The time and frequency domain system brings together the technologies of Nicolet, Gould and Dactron.
A UK water-company project is using natural elements such as bark, wood chips, seaweed and seashells lining water-filled tanks to provide a solution to a smelly problem - the unpleasant odour that can come from wastewater treatment works
The ST series flowmeter is designed for rugged environments typically found in the oil/gas, chemical, electric power, pulp/paper and wastewater treatment industries and applications. Its no moving parts, non-clogging flow sensing element provides direct mass flow output and features built-in temperature compensation. It is suitable for use in a wide range of process and plant gas applications, including compressed air, hydrocarbon gases and inert gases. The ST98 flowmeter has a reliable thermal mass flow sensor in a smart electronics package. It operates over a wide flow range from 0.21 to 172 NMPS in air with a standard flow accuracy of ±1% of reading, ±0.5% of full scale. It is suitable for a wide range of air/gas flow measurement applications, including natural gas or methane monitoring, compressed air metering, industrial HVAC systems, nitrogen blanketing and combustion air.
The Isco 4700 refrigerated sampler for municipal and industrial wastewater applications features a powerful ½ hp compressor with software-controllable temperature settings. The controller displays the sample compartment temperature and logs a 24 h summary to confirm proper cooling and sample preservation.
