Disinfection efficacy testing is usually done with planktonic cells or more recently, biofilms. While disinfectants are much less effective against biofilms compared to planktonic cells, questions regarding the disinfection tolerance of detached biofilm clusters remain largely unanswered. Burkholderia cepacia and Pseudomonas aeruginosa were grown in chemostats and biofilm tubing reactors, with the tubing reactor serving as a source of detached biofilm clusters. Chlorine dioxide susceptibility was assessed for B. cepacia and P. aeruginosa in these three sample types as monocultures and binary cultures. Similar doses of chlorine dioxide inactivated samples of chemostat and tubing reactor effluent and no statistically significant difference between the log(10) reductions was found. This contrasts with chlorine, shown previously to be generally less effective against detached biofilm particles. Biofilms were more tolerant and required chlorine dioxide doses ten times higher than chemostat and tubing reactor effluent samples. A second species was advantageous in all sample types and resulted in lower log(10) reductions when compared to the single species cultures, suggesting a beneficial interaction of the species.

Gas detection alarm maintenance:
1.1 Precautions â—† The gas detection alarm has been strictly calibrated before leaving the factory. Please do not replace the components after installation. If it needs to be replaced, it must be recalibrated.
â—† The sensor life of the gas detection alarm is two years under normal conditions. Due to the different usage environment, its service life may be declining. It should be tested and maintained regularly every year.
â—† The gas detection alarm sensor prohibits the impact of high concentration gas, otherwise it may damage the sensor;
â—† Avoid gas detector alarm often power off, regular power failure will lead to instability of the detection element work;
â—†. In the course of use, it is necessary to periodically check whether the instrument is working properly and the inspection period is at least once every three months.
1.2 Analysis and Troubleshooting of Common Faults â—† After the alarm system is installed and the power is warmed up for the first time, an alarm or fault may occur. At this time, reset the system for a period of time.
â—† The power indicator is off. Check whether the product power cord is connected properly. Check whether the power supply is 24V.
If the connection is normal, contact the manufacturer and return it to the factory for testing.
â—† After the power is turned on, the main unit does not show the main problem of wiring. Check whether the power supply is connected properly and whether the socket is firm. After the power supply is correct, check whether the connectors, such as cables and pins inside the controller, are firm and loose.
Note: It is forbidden to open the cover with the power! ! !
