Performance of a pilot-scale aquaponics system using hydroponics and immobilized biofilm treatment for water quality control

Aquaponics is considered as a promising approach to mass produce both fish meat and vegetable at high rates without discharge pollutants. A novel aquaponics system is proposed to control water quality and enhance nutrition efficiency with high rate immobilized biofilm units, including mass-bio syste...
