[...]Saalbach-Hinterglemm, Austria Fine screening systems are an interesting alternative to primary settling tanks when it comes to changing the sludge stabilisation process from aerobic to anaerobic. Compared with a traditional primary clarifier with a retention time of 0.5 to 2 hours, a fine screen achieves the same or better reduction rates, which take effect within a few minutes whilst requiring only a fraction of the space and volume. Energy savings and biogas yield through carbon removal Switching from aerobic to anaerobic sludge stabilisation can reduce aeration costs by around 20–25%. This [...]

[...]Malta The Ta' Barkat sewage treatment works, often referred to as the Malta South STW, is at the heart of Malta’s wastewater management system. It is situated near Xgħajra on Malta’s south-east coast and officially came into operation in 2011. It is the country’s largest sewage treatment works and treats around 60,000 m³ of wastewater every day. This corresponds to around 80 per cent of the island’s total wastewater volume. The plant uses a modern biofiltration process that alternates between aerobic and anoxic environments to efficiently treat the wastewater. Its commissioning has significantly[...]

[...]Kreßberg, Germany With the new EU Urban Waste Water Treatment Directive (UWWTD, German: KARL), phosphorus removal at sewage treatment works is increasingly coming into focus. At the same time, however, phosphorus loads from sewage treatment works are also one of the reasons why Germany still fails to meet the requirements of the European Water Framework Directive (WFD 2000). Not least for this reason, further measures will be necessary at many sewage works in the future. Flocculation filtration in Kreßberg At the Kreßberg (GK3) sewage treatment works in Baden-Württemberg, this issue is now viewed[...]
