Trial of a ‘Proprietary’ Iron Dosed Sand Filter Plant

Enter your teShirebrook STW is located approximately 5 miles north of Mansfield town center and caters for a population equivalent (PE) of 12,000. As part of the AMP6 Chemical Investigations Programme, Severn Trent Water was required to carry out a full scale trial of a ‘proprietary’ iron dosed sand filter plant on a works serving between 10,000 and 50,000 PE.

The trial is to assess the effectiveness of the process at removing priority hazardous substances/ hazardous substances/specific pollutants (PHS/HS/SPs) as defined under the Water Framework Directive (WFD) – in this case cadmium. In addition, WFD modelling has identified there is a high probability that Shirebrook STW will be subject to a phosphorus consent of approximately 0.2mg/l. Severn Trent Water promoted a scheme to address this and the requirements of the trail in March 2015 and appointed their framework design and build contractor, NMCNomenca, to carry out the work.

Challenge & Solution

In order to satisfy the requirements of the chemical investigation programme and meet the new ultra-low phosphorus discharge consent, Severn Trent Water identified a new technology which promised to fulfil these requirements. Evergreen Engineering provided this technology and process support. The innovation was not the technologies being employed but how the technologies were integrated. At the core of the solution was fundamentally a sand filter which employed chemical dosing and specially selected/graded sand.
