PROJECT: BLOODWATER MANAGEMENT & TREATMENT STUDY

OWNER: Science Council of British Columbia

DESCRIPTION: The study was precipitated by an outbreak of Infectious Haematopoietic Necrosis in farmed salmon in BC and had as its main focus the identification and evaluation of disinfection methods for bloodwater and wastewater from farmed salmon processing. Removal of conventional contaminants such as suspended solids, biochemical oxygen demand and ammonia was also addressed. The study included a review of regulations, treatment and disinfection practices in other jurisdictions where processing of farmed salmon takes place. Other activities carried out included visits of processing and treatment facilities in BC and internationally, the preparation of cost estimates for treatment/ disinfection methods, and identification of scope and cost of pilot tests.
