By upgrading the Gracemere sewage treatment plant, Rockhampton Regional Council has ensured that the local sports fields, golf club and grazing land are fully irrigated by wastewater — once treated — that is discharged from the plant.
A NSW chicken process plant went for safety and energy efficiency in selecting the wastewater pumps for its latest expansion.
PROTECTA-Mag is a concentrated, controlled-viscosity, stabilised suspension of magnesium hydroxide. It prevents corrosion by raising manhole surface pH, thus inhibiting the formation of acid-producing bacteria.
The GHSVSD+ vacuum pump is a dry pump that does not require any sealing water. It features Atlas Copco's latest variable speed technology, providing the ability to match the vacuum pump's speed to the demand of the sewerage system.
In selecting the most efficient wastewater pump, do managers of assets just look for the pump with the best hydraulic efficiency? If so, they may not be winning the pump efficiency game.
The largest operating cost for a wastewater treatment plant (WWTP) is energy. The largest of all WWTP energy consumers — running blowers for aeration. With energy prices continuing to rise, understanding the compressed air demand of your system and selecting the right blower to suit is critical.
The SX Series Vacuum Pumps are operated by compressed air, offering an innovative solution for transferring solids and abrasive materials. The range's ability to handle solids of up to 80% of the pump's inlet/outlet diameter, with transfer distances of up to 1000 m on larger units, makes it a smart solution for difficult material transfer.
South East Water and South Gippsland Water have completed installation of the 200th in-ground pressure sewer pump unit as part of the Poowong, Loch and Nyora Sewer Scheme.
Increasing concerns about CO2 emissions and energy costs has led to greater focus on energy use worldwide.
Partially blocked pumps are extremely difficult to notice and reduce pump effectiveness by up to 40%. When the majority of energy costs of a water treatment plant are due to pumping, pump efficiency is critical.
Developed by Hydro-Plus in conjunction with Gorman-Rupp, the self-cleaning sump addresses many of the issues confronting owners of sewage pump station assets, such as high capital costs, high energy consumption and the cost of intervention for the likes of sediment, solids or fat build-up or for removing chokes from pumps.
A pump's best performing feature can vary greatly; be it hydraulics, electrical, maintenance, non-clogging, unclogging, or wire to water. Careful consideration of your specific requirements is needed to match your organisation's needs with the best fit.
Gorman-Rupp has released the Eradicator Solids Management System, a pumping system for handling solids-laden wastewater. The system features an aggressive, self-cleaning wear plate incorporating a number of notches and grooves, as well as a lacerating tooth that helps break up stringy materials, scrape them off the impeller vanes and pass them through the pump.
Dennis Benson says there are three main factors why Australian wastewater plants are making the switch to screw blowers: controllability, reliability and reduced energy usage.
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.
