Nitrate Analyzer and Control System

RealTech Controls offers two types of analyzers / controllers for monitoring and controlling Nitrate in industrial environments. The Nitrate Analyzer is designed to monitor the nitrification process directly in a wastewater treatment plant’s aeration basin or clarifier unit.
The two technologies are:

Model ETX + HYDRA-DS

  • The Model ETX Nitrate Analyzer uses a HYDRA®-DS combination electrode that simplifies nitrogen (nutrients) and Ammonium measurements.  Its advanced sensor uses ISE technology to measure the concentration of dissolved Nitrate as Nitrogen (NO3-N) in water and features a self-compensating design, where the unit automatically eliminates chloride ion interference, for high accuracy and reliability. While not required for the measurement an optional pH or Ammonium electrode can provide valuable information about the process. Temperature is measured and used to compensate for each of the measurements. If only Nitrate (NO3) is required, then simply use the Model S80 Nitrate ion electrode with the ETX controller, the combination electrode is not necessary.

Model UV6

  • The Model UV6 Nitrate Analyzer incorporates UV light technology for accurate, low-range measurements of Nitrate in water. Nitrate is absorbed by UV light in the range of 190-240 nm, therefore reagents are not necessary making this system cost effective and maintenance-friendly.

Nitrate Analyzer

Model: ETX + HYDRA-DS

Hydra-DS Nitrate Analyzer

Description

The Model ETX with the HYDRA-DS Nitrate sensor uses three electrodes to determine the NO3-N concentration. This incorporates a Nitrate ion electrode, Chloride ion electrode and a pH electrode. It is designed for use in all kinds of municipal wastewater applications, or when ever Ammonium is present in the water. This analyzer has proven itself popular in the industry, and an application article was featured in the Automation World magazine.
If only a Nitrate (NO3) measurement is required, then simply order the model S80 Nitrate electrode individually with the ETX controller.

  • Reliable ISE Technology
  • Nitrate as Nitrogen, NO3-N
  • For Nitrate (NO3 only) measurement, the S80 Nitrate ion electrode can be used separately
  • Measurement Range: 1 ppm to 14,000 ppm (3-11 pH)
  • Temperature Range: 0°C to 40°C (32°F to 104°F)
  • Pressure Range: 0 to 50 psig (0 to 3.5 bar)
  • Accuracy / Repeatability: Better than 5% of calibrated range
  • Response Time: T90 in 10 seconds
  • Electrode Life: 6 to 12 months
  • Auto Compensation for Cl- and Temperature
  • Rugged PVC design
  • Integral Spray Cleaner
  • Industrial wastewater
  • Industrial effluents
  • Aeration Basins
  • Clarifiers
  • Effluent and influent monitoring
  • Process water

Nitrate Analyzer

Model: UV6

TOC Analyzer

Description

Ideal for measuring Nitrate less than 1ppm up to 100ppm, the Model UV6 Nitrate Analyzer is an online sequential sampling analyzer, where a sequence of sampling, analysis, and result processing is performed and repeated using colorimetric methods.

Nitrate dissolved in water absorbs UV light in the range 190-240 nm.
The xenon lamp produces a UV light radiation that pass through the sample water in a quartz measuring cell. The receiver analyzes the light pulses at two different wavelengths, the measurement wavelength (220 nm) and the reference wavelength (270 nm), at which the sample constituents of interest do not absorb. This dual-wavelength measurement allows turbidity and dissolved organic compensation.

  • Ideal for low range Nitrate Measurements less than 1ppm
  • Measurement Ranges (NO3-N): 0-02ppm-30ppm, 0.05-60ppm, or 0.5-100ppm
  • Outputs: Single or dual channel 4-20mA outputs, with 4 x Relays, and MODBUS RTU
  • Easy installation, with user-friendly touch screen interface
  • Epoxy powder coated cabinet with two separate compartments
  • Loss of sample & low reagent alarms
  • Cost-effective, low maintenance
  • Reagent-free system
  • Potable water treatment plants
  • Municipal waste water
  • Industrial waste water
  • Rivers and surface water
  • Ion-exchange and Reverse Osmosis
