The new RTC105 Nitrification/DeNitrification System from Hach Co. provides real-time control of aeration in oxidation ditches and sequencing batch reactors, ensuring energy efficiency and consistent nitrogen levels in the effluent. While some facilities have realized savings by throttling aeration based on dissolved oxygen levels, the new RTC105 offers the opportunity to compound those savings by adjusting aeration based on real time ammonia and nitrate concentrations. Hach’s RTC105 N/DN Module Control System is a turn-key solution with instruments and technology designed to work together. Within an hour of installation, the RTC 105 will be fully operational and controlling the aeration process. Coupled with Hach’s technical support and field service technicians, the RTC105 provides a single point of contact for support of the instrumentation and control system.
