The Results DO, ammonium, and nitrate sensors were installed at critical locations to monitor the process and control distribution of wastewater for the most efficient treatment. Optical UV nitrate sensors were deployed at the influent and effluent of the solids contact tanks (SCT) where the objective was to remove BOD and push nitrification downstream to the nitrifying trickling filters (NTF) as intended. Ammonium ion selective electrode (ISE) sensors were installed in the centrate return to control transfer of stored centrate and to avoid overload of the biological treatment process. Ammonium sensors in the pre-chlorination tanks are used to control the bypass of ammonia-rich secondary effluent around the nitrification process, thereby maintaining the critical ammonia to chlorine ratio for efficient operation of the effluent chloramination disinfection process. The versatility of the multi-sensor IQ SensorNet allows the facility to solve several problems using a single system, not only contributing significant cost savings, but also enabling multiple probes to be used in a variety of locations throughout the plant. The facility has also been able to automate sections of its treatment procedures based on the information that as been collected by the system, significantly accelerating processes. Due to the local weather conditions, the plant was previously unable to use probes that required water to be pumped from an outdoor location to an indoor analyzer as it was highly likely it would freeze in the winter. The IQ SensorNet does not have this problem and the plant can continue to function in freezing weather conditions. Previously, data was manually retrieved from the field. Now it is automated with continuous monitoring and control via the IQ SensorNet system. The information that is collected from the various probes are analyzed for trends and patterns. This can be used to learn more about the finer details of the operation and further increase long term productivity and efficiency.
