EurEau, the European Federation of National Associations of Water Services, is hopeful for the European Commission’s upcoming Urban Waste Water Treatment Directive (UWWTD) proposal.

The illustration shows two pressure control valves. These are very similar but for the fact that one is normally-open and the other is normally-closed. The primary difference between the valves is the location of main orifice in relation to the spring, piston, and valve seat (or seal). Because these valves use liquid pressure to automatically overcome the pre-set spring force, the liquid moves the normally-closed valve to open, and the normally-open valve to close.

Europe’s water sector meets in Malta to discuss how they can maintain affordable water services in an uncertain energy future

Leading voices on digital transformation set out how advancements in data are playing a vital role in revolutionising the water industry.

Today, more sustainable, and climate-friendly technologies are needed to meet the increased demand while continuing to pursue the goals of the Paris Climate Agreement. Hydropower is the only renewable energy capable of generating electricity on a large scale.

The launch of a new challenge from Spring, the water sector’s innovation centre of excellence, and Innovate UK KTN, which connects innovators with new partners, focuses on condition monitoring of electro-mechanical assets for water treatment and distribution.

Watson-Marlow cased drive peristaltic pumps offer superior flow stability, providing accurate and repeatable process control for nutrient feed fermentor applications. The end product of both plant-based and cultivated processes can be extremely difficult to pump due to its sticky and viscous nature.

With growing financial and supply chain pressures, repairing a motor can be an increasingly viable alternative to replacement. But for a repaired motor to perform as well as, or in some cases better than, when it was new it is essential that you get a quality repair from your motor repair partner. Karl Metcalfe, Technical Support at the Association of Electrical and Mechanical Trades, explains what to look for when commissioning a repair.

“The trade fair was a resounding success for us, even though we had fewer visitors than usual,” said Bekir Bayraktar, Global Director Industry Development – Power & Energy for the ProMinent Group, taking stock at the conclusion of ACHEMA 2022. He added, “our focus on innovative solutions for chemical fluid management was right on the mark.”

A simple adjustment to blowers on submerged aerated filter (SAF) technology is bringing significant energy reductions in wastewater treatment, writes Andrew Baird, technical director, WCS Environmental Engineering, meaning cost savings for utilities.
