Aquaculture wastewaters treatment typically consists of screening suspended particles from the primary flow, producing a sludge that must be disposed of. Two experiments were conducted to determine the feasibility of using sand to renovate, stabilize, and dry salmon farm sludge. Data from a preliminary laboratory experiment were used to quantify and design a pilot-scale study facility linked to a salmon farm. The pilot study comprised of coarse sand-filled infiltration beds loaded with either an artificial fish farm wastewater (AFW), backwash water from a microsieve (BW), or sedimented microsieve backwash water (SBW) collected daily from a settling chamber. Results obtained show the feasibility of using sand infiltration to treat salmon farm sludge
