Project involving the upgrading of an existing effluent treatment plant, to accommodate the increased load envisaged following a plant expansion.
The plant was designed to handle up to 3,700 m3 per day of effluent, a proportion being allowed to be discharged to river, the balance being discharged to sewer at minumium cost. The works involved the provision of a new DAF plant with chemical treatment to optimize the level of COD removal. Liquid oxygen was then applied to effluent being re-circulated around high rate towers to enhance their performance.
Finally, the clogged stone media in the final percolating filters was replaced with modern plastic media.
