Case study: Making a Colloide’ continuous filtration plant work How do you turn a non-functioning filtration plant into a stable, reliable system that meets strict discharge standards? In practice, it requires more than technical adjustments alone, it demands a thorough analysis, targeted refurbishment, and intelligent monitoring. For a UK water utility, an existing Colloide® continuous tertiary filtration plant that had struggled to operate consistently was successfully revitalized. By combining technical upgrades, process optimization, and continuous Sand-Cycle monitoring, the plant was brought back to design performance: meeting consent levels for solids, iron, and phosphorus with consistent results. Curious about the approach, the commissioning … Read more

Case Study: Combined Tertiary Nitrogen and Phosphorus Removal Increasingly stringent European discharge limits require innovative and reliable solutions for advanced nutrient removal. In this case study, discover how a full-scale continuous sand filter at the Grobbendonk wastewater treatment plant successfully achieved very low nitrogen and phosphorus concentrations within a single integrated process step. Learn how this pilot demonstrated stable long-term performance and what it means for future plant design and operation. 👉 Read the full article here

Leominster WwTW At Leominster WwTW (2024), a new tertiary nitrifying sand filter process stage has been implemented, along with upgrades to existing assets, to achieve high-quality effluent. For an in-depth look at the project and its impact, read more in the full article here
