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.
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.
The portable Cerlic MultiTracker has helped busy plant operators greatly reduce their daily lab work by providing fast and repeatable measurements for MLSS/RAS/WAS/sludge blanket profile and dissolved oxygen, without having to step into the lab.
Veolia has been awarded a contract to design and build a wastewater treatment system integrated into a greenfield oleochemical production plant in Indonesia.
"If you're not processing your wastewater and getting all the energy you can out of it, it's a waste and you're losing out," says Wiley Process Engineer Heath Barker. In this article, he talks about the latest trends in covered anaerobic lagoon (CAL) systems and how they need to be nurtured and optimised to achieve maximum benefits.
Every year, over 85 million tonnes of biosolids (sludge) are dewatered at most of the 2400 municipal sewage treatment plants in Australia.
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.
Can wastewater treatment become more sustainable? While the goal of treating wastewater is to minimise the impact on the receiving environment, the processes themselves are usually powered by electricity generated by fossil fuels.
