How do you maintain ideal nutrient levels in ever-changing conditions?

Biological treatment is sensitive to imbalances in nitrogen and phosphorus, a condition that can limit the effectiveness of COD/BOD removal and result in permit violations for a number of related parameters. Imbalances also waste money by overdosing urea and phosphoric acid, by incurring effluent discharge costs, and by overusing aeration.

When nutrients are precisely dosed according to TOC load, COD/BOD removal can be efficient and cost-effective. You can ensure compliance on COD/BOD, ammonia and phosphate while saving money. Hach’s RTC-C/N/P Software (formerly RTC-DOS) combines feed forward control and online TOC measurement with feedback control and ammonium and orthophosphate measurements to manage ideal biological efficiency in your wastewater treatment process. Although RTC-C/N/P is a standardized solution, it has built-in flexibility. Define your own nutrient ratios for specific process waste streams, or add an option that supplements the feed forward algorithm with N and/or P measurements that automatically account for variations in background nutrient and TOC values. Add an RTC-SRT module to prevent the growth of nitrifiers, further enhancing COD removal. And in the event that input signals for TOC, NH₄-N, PO₄-P, NO₃-N or flow rate become unavailable, the system will automatically switch to a fallback strategy to protect compliance.

Claros Process Management solutions for BOD/COD removal like RTC-C/N/P 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.
