Recirculating aquaculture systems (RAS) technology has been a focus of much development in recent years and a number of technological innovations have facilitated an increase in the scale of this approach to fish farming and the development of the land-based aquaculture industry. However, although technology is developing rapidly in terms of sensor technology for monitoring water quality, technology for disinfection using ultraviolet disinfection, ozonation and oxidative technologies, and the control and detection of hydrogen sulphide in marine RAS systems, the biofilter is still considered the heart of the system. However, even these technologies are leading to major innovations in biofilter design, operation, and function.<\/p>\n
The conventional nitrossification and nitrification approach of having a biological filter where ammonium is oxidised to nitrite, and thus oxidised further to nitrate with a net consumption of oxygen and alkalinity, has been the heart of RAS systems for many years. Further technologies using various processes of active denitrification, either through annamox processes or anaerobic nitrate reduction to N2 gas, are being developed. However, what if we could remove the need for a biofilter entirely?<\/p>\n
