Sulfur oxidizing bacterial biomonitoring device (
)
Overview
- Biomonitoring device in compliance with Biomonitoring Continuous Automatic Measuring Method using Sulfur Oxidizing Bacteria (to be notified), using sulfur oxidizing bacteria to automatically measure the toxicity of the field
Principles
of analysis
- Measuring the concentration of sulfate ion created by sulfur oxidizing bacteria using conductivity sensor
- Specimens are injected in 2 semicontinuous reaction tanks through alternating operation while active sulfur particles are injected, and changes in conductivity in each reaction tank are measured
- Increase of conductivity in normal state without toxic substance and increase of conductivity after extinction and decreased activity of microorganism due to toxic substance injection are compared to calculate toxicity
- Reference conductivity change rate and conductivity rate change in specimen reaction tank are compared to provide the toxicity of toxic substance in specimen in 0~100% ratio
Equipment
functions
- Toxicity monitoring system that allows continuous online monitoring of injected specimen
- New water specimen is injected to the reaction tank automatically fur the set reaction time and displays toxicity value in real time, allowing prompt action against toxic substance
- Gives an alarm when the set toxicity alarm criteria is exceeded and automatic sampling of water takes place to analyze the substance causing toxicity
- Toxicity value is sent to the integrated management system using various output value types
Equipment
features
- Sulfur oxidizing bacteria are fixated to the sulfur particle that is supplied to the reaction bank, used as feed, so no separate nutrition supply is necessary
- Long-term maintenance without sulfur particle replacement (1-2 months)
- Low maintenance cost for stable operation of equipment
Applicable areas
- Toxicity monitoring in intake stations or purification plants
(In accordance with the Enforcement Regulations of the Sewerage Act Appendix 3. Facility Criteria for the Safety and Security of Specific Criteria of Water Supply Facility, purification facilities over 10,0000ton of intake facility capacity must install biomonitoring at intake and purification plants that measures raw water to prepare for the inflow or harmful microorganisms or chemical substances into water supply source) - TMS toxicity monitoring
- Toxic substance monitoring in buffer storage facilities in industrial complexes
- Water quality monitoring against constant pollutants in streams and lakes
