You are contacted by a salmon farm that produces a significant amount of liquid industrial waste (RILES), which is part of the effluent from its production process. This current has a COD of 950 mg/L, and a BOD5 of 750 mg/L. Based on your knowledge of water pollution and treatment, you are asked to:a) Recommend a treatment system for the effluent, considering that the plant is authorized to release treated water with a BOD5 concentration of 50 mg/L into a nearby lake.b) The salmon farm tells you that the contamination in the effluent comes mainly from the excess of concentrated feed that is given to the salmon and from their feces (solid and liquid waste from the digestion of the feed). Indicate 3 contaminants that you would expect to find in the effluent, indicating the ecological risk that the direct discharge of each one to the lake poses.

Question

You are contacted by a salmon farm that produces a significant amount of liquid industrial waste (RILES), which is part of the effluent from its production process. This current has a COD of 950 mg/L, and a BOD5 of 750 mg/L. Based on your knowledge of water pollution and treatment, you are asked to:
a) Recommend a treatment system for the effluent, considering that the plant is authorized to release treated water with a BOD5 concentration of 50 mg/L into a nearby lake.
b) The salmon farm tells you that the contamination in the effluent comes mainly from the excess of concentrated feed that is given to the salmon and from their feces (solid and liquid waste from the digestion of the feed). Indicate 3 contaminants that you would expect to find in the effluent, indicating the ecological risk that the direct discharge of each one to the lake poses.
