Utilizing OSEC® onsite generation of chlorine to mitigate shortages

Dŵr Cymru Welsh Water’s Hirwaun water treatment works is a small works (5Ml/d) which treats raw water from the Penderyn upland reservoir. Treatment is by coagulation with ferric sulphate and lime, flocculation and clarification by DAF. The clarified water is dosed with lime and this is followed by first stage filtration in four rapid gravity filters, intermediate electrochlorination and orthophosphoric acid dosing, and second stage filtration in four pressure filters. Final disinfection is by electrochlorination. The original electrochlorination plant was an Evoqua OSEC® packaged unit installed over twenty years ago and had reached the end of its asset life.
