  • Provides the data and solutions to these issues so you can make the right decisions and be more efficient
  • Hach’s RTC (Real Time Control) solutions are complete off-the-shelf systems that adjust treatment processes in real time, keeping your facility compliant while reducing treatment costs. Controlling your process has never been so simple.
  • Fulfill your discharge consents AND keep your treatment costs in check – even when faced with changing conditions and sudden load peaks.


Eliminate uncertainty. Increase confidence.
Welcome to the Power of Claros.

Are you sure your plant is efficient?

Manage your process in real time based on constantly changing process conditions.

Wasting money on overtreatment?

Reduce your risks and overtreatment costs.

We have several modules tailored to your specific needs:

  • RTC-Phosphorous Removal Module: Optimize phosphorus removal by measuring concentration and flow in real time and adjusting chemical dosing.
  • RTC-Nitrification Module: Optimize nitrification processes by continuously measuring ammonia load and adjusting DO concentration in real time for significant energy savings.
  • RTC-Nitrification/Denitrification: Continuously measure ammonia and nitrate concentrations to determine the optimal times for nitrification and denitrification.
  • RTC-Sludge Thickening Module and RTC-Sludge Dewatering Module: Control polymer dosing in real time to significantly reduce polymer costs, increase your biogas yield, and reduce maintenance and guesswork.
  • RTC-Nutrient Dosing Module: Optimizes dosing of nutrients like urea and phosphoric acid on industrial wwtp’s to ensure a specific C/N/P balance.
  • RTC Sludge Retention Time Module: Calculates the required amount of excess sludge to be removed to adjust an aerobic sludge age ensuring stable nitrification and low energy cost for BOD removal.
  • RTC-Denitrification Module: optimizes the internal recirculation flow of the nitrate-containing water from effluent nitrification to the denitrification zone. Thereby the total nitrogen removal is improved and the risk of denitrification processes disturbing the sedimentation process in the final clarification tanks is reduced.
  • RTC-Simultaneous Denitrification Module: It is designed for simultaneous denitrification in oxidation ditches. It optimizes nitrification and denitrification processes by adjusting the size of the areas allocated to nitrification and denitrification based on the continuous measurement of ammonium and nitrate. This ensures consistent effluent ammonium values and enhances your DO control system for unprecedented energy savings.
