A toxicity online monitoring system using sulfur-oxidizing bacteria as the test media to measure the toxic contaminants in water

The sulfur-oxidizing bacteria grow on the surface of sulfur particles under aerobic conditions. They use oxygen as the final electron acceptor to oxidize sulfur particles and convert sulfur to sulfate

Increasing of sulfate concentration means that the sulfur-oxidizing bacteria are growing steadily, but if a toxic substance is present, the activity of sulfur-oxidizing bacteria decreases, thereby decreasing the sulfate concentration

The concentration of sulfate ions generated by the sulfur-oxidizing bacteria can be measured using an electrical conductivity sensor, afterwhich the toxicity can be estimated by comparing the increase rate of the measured electrical conductivity in the normal state without toxic substances and the change of electrical conductivity due to microbial death and reduction of activity when toxic substances are present

Toxic monitoring system for on-line, continuous monitoring of samples

Possible to quick response to toxic water pollution event by real time monitoring

Possible to analysis of source of toxic water pollution by analysis of autosampled water When the set toxicity level exceeds the alarm standard

Toxicity data is transmitted in various output formats to the integrated management system

S-TOMS does not require an additional supply of nutrients, since the sulfur-oxidizing bacteria use the sulfur particles as a food

The system can be managed for a long time without replacing the sulfur particles, and stable operation is possible with low maintenance cost

It is highly sensitive to reactions of toxic substances such as heavy metals and pesticides since it uses microorganisms as the test media and minimizes the measurement error by using an electric conductivity sensor
