Leominster’ sewage post treatment plant up and running Dwr Cymru Welsh Water invested in upgrading its Leominster STP to meet more stringent criteria for phosphorus. As part of the program tertiary continuous filters have been implemented and put in operation as from February 15th 2024 onwards. Main contractor Morgan Sindall and contractor Nijhuis Industries UK & Ireland executed the work. We designed and supplied the filter units.Besides P removal the tertiary treatment plant is used for biological nitrification to convert ammonia into nitrate-nitrogen. The final effluent is discharged into the River Lugg.The upgrade of the treatment works is part of

Bio-GAC technology for removing medicine residues During the AquaNL exhibition the latest results regarding removal of medicine residues with our biologically enhanced moving bed granular activated carbon filtration (bio-GAC) technology have been presented. The technology combines the adsorption and bio regeneration of medicine residues and physical-chemical phosphorus removal. Hence it will be an appropriate solution to both meet the criteria for nutrients and medicine residues as indicated in the EU Water Framework Directive. Hans Wouters explained the objectives of the research and highlighted the process set-up. For those who could not attend and for those who would like to know

Industrial waste water treatment: turning a pilot into full scale Last week our client, an international fertilizer processing company, started the construction of the foundation for a new waste water treatment plant, prior to discharging onto surface water. The main goal is to remove phosphorus to meet the new consent levels.The initial ideas for the set-up of the waste water treatment plant have been composed and tested by Geert Notenboom (http://www.wacono.nl/) and Anthoney Marta (https://www.amart.nl/).Prior to designing the full scale plant (capacity 60 m3/h), a pilot plant is operated to determine the final basis of design and control philosophy. The

Tertiary filter refurbishment work completed at Great Glen STW, UKUK 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 adjusted and
