Approved Site Application

Any potential user should ensure, in consultation with the manufacturer, that the monitoring system is suitable for the intended application. For general guidance on monitoring techniques refer to the Environment Agency Monitoring Technical Guidance Notes available at www.mcerts.net

On the basis of the assessment this instrument is considered suitable for use on treated wastewater and untreated wastewater applications.

For the field test, the Protoc 300 analyser was assessed on the basis of a three month field trial installed on an urban river application.

Chloride levels of less than 2000ppm are desirable to prevent corrosion problems, for levels above 2000ppm, follow manufacturer's guidelines

Description:

The Protoc 300 TOC analyser measures a sample stream continuously for organic carbon content. Sample is mixed with an acidified reagent containing sodium persulfate. The mixture of sample and reagent is sparged with a carrier gas (usually compressed air) to remove inorganic carbon and dissolved carbon dioxide. The remaining liquid, which now contains only organic carbon compounds, is pumped into the reaction vessel. A strong source of ultra-violet light promotes an oxidation reaction between the organic and persulfate, producing carbon dioxide. A stream of carrier gas diffusing at the bottom of the reaction vessel, transfers the carbon dioxide through a gas drying system into a non-dispersive infrared detector. The amount of carbon dioxide produced is directly proportional to the organic carbon content of the sample over a specific measuring range determined by the application.

The analyser may be set up to measure total organic carbon (TOC) or total carbon (TC). In the latter case the sparging of the sample is omitted.

The analyser is calibrated by passing a standard test solution through the analyser. The standard contains a known level of carbon and the detector is adjusted to display the correct reading. Solenoids are used to switch either the sample or the standard solution through the analyser.
