Tertiary filter refurbishment work completed at Great Glen STW, UK

by

Tertiary filter refurbishment work completed at Great Glen STW, UK UK water utility Severn Trent is optimizing waste water treatment plants for further P removal. Aspart of this scheme the existing tertiary filter plant at Great Glen STW, constructed in 2018, wasrefurbished. Also the process set-up has been altered to optimize filter operations at varying processconditions. The work has been executed by Brightwork in close collaboration with MMB andAlphaPlus. The project goal is to remove phosphorus by inline tertiary dosing of coagulant, and meet the morestringent criteria for P and Fe in the final effluent. Operational conditions had to be … Read more

New purification technology for micropollutants removal looks promising

by

Our research to remove micropollutants, such as medicine residues, and phosphorus in one reactor, has been picked by the Dutch radio broadcasting RTV Drenthe. I a short interview the backgrounds and drivers of the research are discussed. The pilot unit, consisting of a biologically enhanced granular activated carbon filter reactor, is in full operation at WwTW Emmen, the Netherlands. Regular samples are taken to determine the removal efficiencies for a large number of medicine residues. Also, eco-toxicity is monitored and a variety of other parameters, including phosphorus.     Link to the article Listen to the broadcast on rtv Drenthe … Read more

New tertiary process to remove micropollutants and phosphate from municipal treated wastewater tested at WwTW Emmen

by

A pilot plant has been started at the waste water treatment plant of Emmen, Waterschap Vechtstromen. This pilot study, called Bio-GAK, aims to find an affordable and sustainable solution for removing micropollutants from treated wastewater before the water is discharged into surface water. This method removes both medicine residues and phosphate.   Bio-GAK pilot The purification technique applied is using granular activated carbon filter media. The filter bed is aerated to stimulate biological conversion within the filter bed. Hence the regeneration frequency of the carbon filter may be extended. The Bio-GAK process uses the continuous filtration technology. This means that … Read more

Presenting at European Waste Water Management Conference 2022

by
EWWM 2022

This year’s EWWM (European Wastewater Management) conference is scheduled for July 12th and July 13th at the Hilton Birmingham Metropole, UK. We are pleased to present live a joined paper together with Van Remmen UV Technology and Waterboard Brabantse Delta. It is about the strong features of combining tertiary sand filtration and UV technology, based on results obtained at the waste water treatment plants of Kaatsheuvel (the Netherlands) and Växjo (Sweden).   We are pleased to present a paper about the potential of tertiary sand filtration and UV radiation to meet tomorrow’s effluent criteria. The paper has been composed by Van … Read more
