Description

To meet the efficiency demands of their investment programmes, water utilities are seeking innovative solutions to achieve targets using their existing infrastructure. One technology developed in Germany, and proven there and elsewhere in the world to meet this challenge, is now being introduced to the UK sector by EPS to improve the efficiency of Final Settlement Tanks (FSTs). Known as ‘Adapt’, it applies advanced Computational Flow Dynamic (CFD) based design to create and optimise a variable inlet system in the FSTs to respond to changing flow and load conditions. The solution gives real-world benefits, increasing the effective capacities of FSTs, whilst significantly improves the quality of the effluent by reducing the discharged phosphorus and suspended solids. In many plants where this technology had been used, it has been possible to reduce or even remove tertiary filtration assets whilst still meeting tight phosphorous discharge limits. Not only does this technology reduce P and TSS levels, but the lower tertiary power demands, in combination with the potential to reduce the number of new FSTs needed to be constructed, offers a reduction in the Capex, Opex and embodied carbon impact of wastewater treatment plants.
