Ammonia nitrogen is an important water quality parameter that needs to be monitored in the aquaculture industry. Daruifuno's DUC2-NH online ammonia nitrogen controller can be connected with the Ammonia Sensor to realize real-time online continuous monitoring of the ammonia nitrogen value of the water quality. This Ammonia Controller has 2 SPST relay outputs, two 4-20mA current outputs and RS485 communication. The ammonia controller can control the cleaning of the ammonia sensor in water. For the aquaculture industry, how to control the ammonia nitrogen content in water?
1. Reasonably control the amount of feed and stocking density to avoid over-feeding and over-close feeding.
2. Strengthen the ventilation and water flow of the water body, increase the content of dissolved oxygen in the water body, thereby promoting the oxidation and decomposition of ammonia nitrogen. 3. Using technologies such as biological filters to convert ammonia nitrogen into harmless nitrite and nitrate. 4. Regularly clean the breeding ponds and filters and other facilities to avoid excessive accumulation of organic matter in the wastewater. 5. Select the appropriate species of aquatic organisms. Different species of aquatic organisms have different adaptability to ammonia nitrogen. Selecting the appropriate species can reduce the discharge of ammonia nitrogen.
