The DAF-AQ dissolved air flotation system is specifically designed for aquaculture wastewater treatment and water recirculation in fish and shrimp farming operations. Utilizing advanced micro-bubble dissolved air technology, it efficiently removes suspended solids, uneaten feed particles, fish feces, algae, and colloidal organic matter from recirculating aquaculture systems (RAS) and pond discharge water. With 2-150 m3/h capacity and TSS removal above 90%, this DAF system enables sustainable water reuse and environmental compliance for Latin American aquaculture producers in Chile (salmon), Ecuador (shrimp), Brazil (tilapia), and Peru (trout).
