The Industrial Effluent Discharge Analyzer is designed to provide continuous measurement of VOCs in industrial and trade effluent discharge points. Regulations on the quality of effluents from trade premises and factories are getting stricter and stricter and VOCs are now in the spotlight.

Thanks to this analyzer you can monitor your effluent discharge and make sure that you detect promptly any problem, avoiding expensive fines and PR disasters. The system comprises the analyzer and the sampling system. As the water goes through the sampling tank, VOCs dissolved in the water move into the gas phase.

Multisensor’s sampling system helps the VOCs to get in the gas phase. This gas is then continuously analyzed and the VOCs concentration in the water is determined.

Industrial Effluent: The Problem

Discharge of VOCs into wastewater is an endemic problem in engineering, chemical processing, food and beverage production and other industrial processes.

Spills can lead to illegal discharges, pollution, fines and PR disasters.

For this reason, some industrial facilities have purification plants to remove the bulk of these contaminants from the water before it is discharged, but even these suffer from failures and can be over run.

The cost of not monitoring your effluent

When spills happen large fines can be issued by the Environmental Agency and local, national and social media can turn an accident into a PR disaster with long-term implications.

Additionally it is likely that regulatory bodies will ask for expensive on-line TOC analysers to be installed, which require a lot of reagents and maintenance at a very high additional cost.

The Solution

By installing a VOC Industrial Effluent Discharge Monitor at the effluent, you can be notified as soon as the values start to increase and take appropriate action, avoiding all the problems associated with unexpected pollution events.

The VOC Industrial Effluent Discharge Monitor is used to check the industrial effluent from industrial facilities and business premises to ensure that it is complying with environmental regulations.

Its contactless measurement technique means that:

  • It does not need reagents
  • Requires little or no maintenance between services
  • It’s robust and reliable
  • It is cost effective

What does the VOC Industrial Effluent Discharge actually measure?
It measures the concentration VOC in water measured against a target gas standard (usually toluene). Other compounds can be targeted.
How often does the instrument provide a reading?
The instrument provides a reading via the 4-20 mA output continuously.
What is the reported value?
The reported value is Total VOCs in the effluent water, in ppm, is in the range from 50 ppb to 5 ppm
What is the principle of operation
The system samples the air above the effluent/sewage continuously; this air is then passed through the sensor which reacts with VOCs and measures their concentration. The concentration is then reported via the analog output.
How is the analyzer calibrated?
The instrument is factory calibrated against toluene.
What are common target gases?
Petroleum Gas, Methane, Iso Butane, Kerosene, Ethanol, Diesel, Iso-butylene, Toluene, Acetone, Xylene, Heptane, Benzene, Methanol Mercaptan
What is the required maintenance? Is it expensive?
The instrument requires a service every 6 months to replace some low-cost components such as activated carbon filters and to make sure that there are no air leaks.
What is the warranty?
Every instrument comes with 1 year warranty from the shipment date
How does the analyzer alert the user to high concentrations of gas?
It incorporates a relay which is switched at a user definable threshold. This can be hardwired to valves/pumps and so on to stop processes very quickly. Alternatively the users SCADA system can also be used.
