AMMONIA CONTROL SYSTEM FOR AQUACULTURE

摘要

Some embodiments provide a recirculating aquaculture system for aquatic life. The system includes a culture tank, a first sensor configured to measure a current ammonia concentration in the culture tank, a biofilter in fluid communication with the culture tank, a variable speed pump configured to circulate water through the culture tank and the biofilter, and a controller in communication with the first sensor and the variable speed pump. The controller is configured to retrieve a maximum ammonia concentration, retrieve the current ammonia concentration from the first sensor, and compare the current ammonia concentration to the maximum ammonia concentration. The controller is also configured to control the variable speed pump to increase a current water flow rate through the system when the current ammonia concentration is greater than the maximum ammonia concentration.
