MX Aquaculture
Wastewater from Aquaculture Industry
Discharges from aquaculture facilities can affect the water environment in the receiving body if overloaded with organic matter and nutrients. To avoid negative environmental impacts from land-based aquaculture farms, the effluent water must be treated to remove traces of feed and excrement.
Mestraco's solution has been tested on wastewater and has proven to be an effective solution for the treatment and management of this water. Along with the suspended particles in the water, we also reduce levels of nitrogen, phosphorus, and TOC (total organic carbon).
Images of wastewater from a flow-through system. The bottle on the left shows wastewater that, until now, has been transported by tanker truck and delivered to an approved landfill. The two bottles on the right show how the water looks after different retention times in the MX treatment reactor. Practically all phosphorus and over 80% of the nitrogen have been removed in the treatment process.

Wastewater from Slaughterhouses
Wastewater from salmon and fish slaughterhouses must meet the new and upcoming BAT (Best Available Technology) requirements. These regulations, set by the authorities, require the use of the best available methods and technologies to minimize environmental impact. BAT requirements often specify concrete limits for various substances released. Mestraco's MX Superclean solution separates fine particles and fat in the bloodwater without the use of filters. A significant portion of phosphorus and nitrogen is also removed in the same process. This simplifies and reduces the need for water disinfection before discharge into the receiving body. Mestraco is also working on providing solutions that can be directly connected to existing treatment plants as an upgrade. This upgrade can be implemented relatively quickly and at a significantly lower cost compared to investing in new treatment plants.
Suspended particles and blood aggregate into flocs
A section showing how suspended particles and blood aggregate into flocs after treatment in the MX process. Air is a natural part of the process, binding to the flocs and lifting them to the top of the MX reactor tank. The spongy sludge formed during the process is easy to remove using various methods (filter belt, sludge bag, etc.).
