Are your aerated/non-aerated intervals balanced for maximum NH₄-N and TN benefit?

For intermittently operated plants and those with sequencing batch reactors (SBR), fixed periods for nitrification and denitrification can’t adequately address varying inflow conditions. Making assumptions about the ammonia or nitrate load in your mixed liquor can lead to overuse of blowers, inconsistent sludge, and TN compliance violations.

Instead, try load-dependent control of your aerobic and anoxic cycles. Hach’s RTC-N/DN and RTC-N/DNSBR Software use real-time measurements of NH₄-N and NO₃-N levels in the treatment basin to ensure the correct level of DO is introduced during the nitrification stage. This prevents nitrate-exhaustion-causing orthophosphate release, or untreated nitrate spiking total nitrogen, during the denitrification stage. In addition, real-time control on NH₄-N, NO₃-N and DO creates transparency, ensures compliance and increases process efficiency. Despite being standardized solutions, RTC-N/DN and RTC-N/DNSBR have treatment flexibility built in, allowing you to prioritize ammonium or total nitrogen limits, to activate an orthophosphate feedback control loop, to install an additional DO controller, and to specify your desired fallback strategy that will protect compliance in the event that input signals become unavailable.

Claros Process Management solutions for nitrification/denitrification like RTC-N/DN and RTC-N/DNSBR (tailored to the specific needs of plants with sequencing batch reactors) are designed to make the most of your plant’s real-world conditions by transforming every uncertainty into an opportunity for measurement, responsive action, and savings.
