4-20mA pH ORP Controller Meter for Sewage Treatment

pH refers to a measure of the acidity or alkalinity of a solution. It is used to measure the concentration of hydrogen ions in a solution. The pH scale ranges from 0 to 14, with 7 being neutral, below 7 being acidic, and above 7 being alkaline. Usually we use a Ph Sensor and a Ph Orp Controller to continuously monitor and control the pH value of the water. pH analyzers play an important role in wastewater treatment plants. The composition of the sewage is relatively complex, and the pH in the sewage is too high or too low to cause corrosion or blockage of the treatment equipment. Therefore, using an online Ph Controller with a pH sensor can monitor the pH value of the sewage, and control the dosing pump through a relay , Adjust acid and alkali and other chemical substances to adjust the pH value of sewage to achieve the best treatment conditions and protect the normal operation of treatment equipment. In the process of sewage treatment, different treatment processes have different requirements for the pH value of sewage. The PH ORP Controller can control the pH value of sewage according to the requirements of different treatment processes and improve the treatment effect. After the sewage treatment is completed, when it needs to be discharged into the natural environment, if the pH of the sewage is too high or too low, it will pollute the environment. Therefore, it is necessary to use a pH ORP controller to control the discharge port to ensure that the pH value of the discharged sewage is within the required range and reduce environmental pollution.
