Wastewater / effluent
The client is a manufacturer and processor of coated fish products and fresh fish, with the effluent produced being discharged to the public sewer via four effluent mains.
Alpheus was invited, together with others, to look at ways of improving the quality of effluent discharged to the sewer.
Alpheus realised that efforts had been made to improve the effluent quality over a number of years, and therefore proposed a review of the challenges faced: looking at historic data, implementing an intensive sampling regime to establish current effluent quality, and carrying out on-site trial with a variety of technologies to identify the most appropriate solution.
Initially Alpheus was awarded a consultancy / feasibility contract to develop the initial proposal into a fully costed and robust solution. The detailed solution was accepted and Alpheus secured a turnkey contract to design, build and commission a new wastewater treatment plant.
The existing effluent treatment on site comprised a series of screens and interceptor pits prior to discharge to the public sewer.
The Alpheus solution retained and reconfigured the existing system and added oil skimmers to remove fats, oils and grease, and lamella plate separators to remove solids and associated COD.
