First, pre-test information input;
Second, the test operation: 1) Install the sample, 2) set the test process, 3) start the test operation, 4) end the test;
Third, the results of preservation and curve analysis;
Fourth, test report.
Here are the first and most basic information inputs (in the case of experiments with metallic materials):
The common test method of metal materials only plays a role of helping information for users. When users do different materials tests, they should refer to the relevant and up-to-date national standards to determine the control method and control speed of the test process.
1. After entering the main program interface of the test, you should first set the various information, and click the set shortcut button to enter the “setting window†to set various options.
2. Select the test standard and sample parameter settings in the data options of the test control panel. Click on the input sample data, and then input the sample number, original size, original standard moment and so on.
A bench-scale study was conducted using water from a drinking water treatment facility on Lake Ontario to investigate water quality and disinfection impacts of chlorine contamination in a chlorine dioxide solution applied for primary disinfection. Levels of chlorine contamination were varied between 0% (Pure Chlorine Dioxide) and 20%, with a chlorine dioxide dose of 1 mg/L. The chlorine did not significantly affect the rate of chlorine dioxide decay in the water. The chlorine reduced chlorite formation, but led to a corresponding increase in chlorate formation. Trihalomethane and haloacetic acid concentrations varied with the amount of free chlorine present in the chlorine dioxide solution. Levels of Bacillus subtilis endospore inactivation were similar for solutions containing pure chlorine dioxide and a 20%:80% chlorine:chlorine dioxide mass ratio (for the same total chlorine concentration). Since chlorine alone has been reported to be very ineffective against these endospores, the results suggest that the disinfection effectiveness of the mixture was greater than the effectiveness predicted from each of the two disinfectants acting alone.
