The production plant manufactures and processes both coated fish and fresh fish products. The effluent produced by the manufacturing and processing site is discharged to the public sewer via four effluent mains.
Alpheus were invited to look at ways of improving the quality of effluent discharged to the sewer. We proposed a comprehensive review of the challenges faced, looking at historical data, implementing an intensive sampling regime to establish current effluent quality, and carrying out on-site trials with a variety of technologies to identify the most appropriate solution.
The consultancy work undertaken by Alpheus assessed Dissolved Air Flotation (DAF) technology, the traditional route for effluent treatment of this type against simpler and more cost-effective lamella technology. We determine that lamella technology would meet the treatment needs and offer a cost-effective treatment method without the operational costs associated with DAF technology.
