The matters needing attention in the PH value in sewage
Changzhou Chengfeng warmly reminds you that when selecting an electromagnetic flowmeter, the materials inside the flowmeter's electrodes determine the useful life of the flowmeter. Therefore, attention must be paid to these aspects in a timely manner. The pH indicates the pH of the sewage. It is the logarithm of the reciprocal of the hydrogen ion concentration in the water. Its range is 0-14, and the pH value is equal to 7, then the water is neutral and less than 7 is acidic. The smaller the value is, the stronger the acidity is, and the alkalinity is greater than 7. The bigger the alkalinity is, the stronger it is.
The pH value in the sewage has a certain influence on pipelines, pumps, gate valves and sewage treatment structures. The pH value of a sewage treatment plant that uses mainly domestic sewage is usually 7.2 to 7.8. Excessively high or low pH values ​​indicate the presence of industrial wastewater. Too low a value can corrode pipes, pump bodies, and may cause damage. For example, sulphide in sewage will generate H2S gas under acidic conditions.
At high concentrations, headaches, runny nose, suffocation, and even death can occur during operation. For this reason, it has been found that the decrease in pH must be monitored to find sources of pollution and countermeasures must be taken. At the same time, the allowable pH range of biochemical treatment is 6~10, too high or too low can affect or destroy biological treatment. Therefore, in the process of using a sewage flow meter, special attention should be paid to these matters.
