Inland aquaculture of marine organisms requires a combination of biological and mechanical filtration methods to
maintain optimal water quality. Filter systems are backwashed on a regular basis to maintain their effectiveness,
which results in the accumulation of sludge and the loss
of water. One option to reclaim water is to allow the backwashed wastewater to settle in a container, and then decant
the water back into the culture system. However, the anaerobic nature of a settling tank prevents the aerobic nitrification of ammonia (Boopathy et al., 2005). By transferring
water from a simple settling tank, excess nitrogen may be
added to the culture system
