The University of Queensland has developed technology which uses free nitrous acid to remove biofilms that adhere to the inner surfaces of sewer mains, thus controlling odour and corrosion.
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.
Three Kaeser EBC series blower systems were recently installed at Water Corporation's Collie Wastewater Treatment Plant (WWTP) to efficiently and reliably meet the compressed air requirements of an upgraded process aeration system.
Heathrow Airport Water Services Department trialled and installed Xylem's latest Flygt wastewater pumping system in an effort to solve chronic clogging issues at one of the airport's wastewater pumping stations. As well as delivering consistently clog-free pumping, the system also reduced energy consumption by 53% at the pumping station.
Emerson Process Management is replacing an outdated SCADA system and remote terminal units (RTUs) used throughout Hampton Roads Sanitation District's (HRSD) vast wastewater collection system.
An upgrade by Richmond Valley Council of its Casino sewage treatment plant (STP) has paid immediate dividends by withstanding the fury of June's storms and flooding without suffering any polluting spills or odours.
ACTI-Mag is a concentrated, stabilised suspension of magnesium oxide. It is particularly effective for neutralisation and heavy metal capture in industrial wastewater treatment plants, municipal wastewater treatment plants, flue gas treatment (sulfur dioxide, chloride removal), sugar and chemical processing.
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.
