The Hydrotech Discfilter showed significant cost advantages compared to alternative processes when treating final effluent to better than 15 mg/l TSS. The Hydrotech Discfilters from Veolia are also going to be installed by South West Water at their Lanner St Day sewage treatment works (30 L/s) and by Thames Water at Merstham sewage treatment works (60 L/s) in projects due for completion in 2010.
Hydrotech Discfilter modules are available in four ranges up to 1,000 L/s and can be supplied on steel frames for building into concrete chambers or as stand-alone stainless steel tank units.
