Nitrification. Under Control. 

Hach’s off-the-shelf RTC-N System adjusts the nitrification process in real time, helping you meet ammonia control limits while reducing money spent on excessive and unnecessary aeration.

Maintain Compliance

Adjusting aeration based on real-time data makes your process more consistent. The RTC-N system continually monitors ammonia levels in your water and responds automatically to load changes, keeping your facility compliant. Controlling your process has never been so simple.

An Off-the-Shelf System

RTC is a plug-and-play system that is ready to use after a very simple set up. Minimal downtime is needed to install the system and once installed Hach will help you program your setpoints so you are fully prepared to monitor and treat your water in real time.

Save Money on Treatment

The RTC-N module is preprogrammed with algorithms that adjust blowers to maintain your desired DO setpoint. By treating only when needed, you save on energy costs.

When We Say Service, We Mean Service!

Hach’s complete Service package includes routine maintenance visits and warranty repairs.  A team of remote technical experts will monitor your system and send you reports so you know your system is working properly. It's like having a Hach Technician at your facility.

AMTAX sc:  High precision process-instrument for the determination of ammonium in water, waste water and activated sludge. Outdoor enclosure. Incl. filter probe with 5m hose. 230V AC/50 Hz power supply.
  • Automatic cleaning and calibration
  • Wall mountable, rail mountable and mountable on a stand
  • With integrated filter probe
  • Many additional versions available on request


The sample preparation is done by an integrated sample preparation probe with 5 m heated hose. The filtration probe is operating at 230V. Evaluation and operation with SC 1000 Controller. The analyser is equipped with an insulated enclosure for outdoor installation. The sample can be analysed before any degradation. The ammonium in the sample is first converted to gaseous ammonia. Only the NH3 gas passes through the gas-permeable membrane of the electrode and is detected. This method guarantees a wide measuring range and is less susceptible to cross-sensitivity methods that make use of an ion-selective electrode (ISE). in situ membrane filtration; filter modules are exchangeable.

SC 1000: Local measurement of several parameters
Probe module for connecting up to 4 SC sensors, with analogue output card with 4 x 0/4-20mA OUTPUT, relay card with 4 break contacts (NC), and EU power cord for 100-240V AC power supply.
  • Flexible: individually configurable
  • Future-safe: always expandable
  • Intuitive operation: display with touchscreen
  • Many additional versions available on request


A controller system to which SC sensors can be connected and from which they can be controlled consists of a single SC 1000 display module and one or more SC 1000 probe modules. The system is configured modularly in line with customer-specific requirements and can be expanded at any time with additional measurement stations, sensors, inputs, outputs and bus interfaces.
The probe module is used to connect SC sensors to a measurement station. Several probe modules can be linked to create a SC 1000 network.

RTC-N

 Nitrification control module for NH4-N- load dependend O2 regulation. 1-channel version.
  • Reduced costs for aeration
  • Ensured consent performance


With the Nitrification module the required O2 concentration is calculated based on NH4-N influent load and effluent concentration. Combined feed forward and feed back control increases efficiency of treatment processes as well as consent performance. Even with extreme shock loads effluent limits are met.

LDO sc: The new LDO generation - even simpler, even more reliable and even more cost-effective
Immersion or flow-through probe with optical luminescence measuring method. Calibration-free & drift-free.
  • Extremely reliable - 36-month warranty on probe
  • The optimised temperature sensor and the new 3D factory calibration make O2 measurement even more accurate
  • No electrolyte or membrane changes necessary
  • Remote functions for simple and convenient data transfer via Internet and SMS


No electrolyte or membrane changes due to the optical measurement method. The new LDO probe ensures there is only a minimal amount of maintenance. The luminescence method means the measurement is unaffected by any type of interference.
Years of practical experience have shown that this method completely overcomes the disadvantages of traditional electrochemical O2 measurement methods.

SOLITAX: For the lowest turbidity and the highest solids content
Stainless steel high-precision built-in process probe to determine turbidity and suspended solids. Colour independent method with dual-beam infrared/scattered light photometer.
  • Color-independent measurement of solids
  • No calibration
  • Excellent correlation to laboratory analysis
  • Proven cleaning system
  • Improve overall efficiency of the plant


90° turbidity measurement according to DIN EN ISO 7027. The backscatter photoreceptor measures suspended solids accurately in accordance with DIN 37414. A single correction factor replaces time-consuming multipoint calibrations with dilution series. The measurement data is displayed and processed with the help of a controller. The sensor is for pipe use only! A welding neck and a fitting are essential for pipe installation.

RTC–N is handles influent ammonia spikes, immediately adjusting aeration to bring levels back to the programmed level. Effluent values are stabilized immediately after commissioning and the system is up and running less 24 hours after installation.


The RTC–N System for aeration control is designed to control aeration based on the real time ammonia load. This has proven to reduce aeration energy consumption by 10 to 30%, depending on the treatment plant. This is a treatment plant where one aeration tank is controlled with the RTC–N Module, and another aeration tank is controlled with the existing dissolved oxygen setpoint at 3.0mg/L. The RTC–N aeration tank uses much lower DO concentrations, which add up to 20% savings!
