System for controlling the quality of water real-time for reducing pipe corrosion in a water supply pipe

摘要

The subject innovation relates to a water treatment process can also be introduced into the water supply pipe network using the process of the processing facility in the real-time quality index CCPP for reducing corrosion of a water supply pipe can be adjusted to meet the anti-corrosion condition control device. ; This devise is the drug regulation takes place on the last sector of jeongsuji earlier stage of the previous stage ie coagulation process earlier stages of various chemicals added to drinking water treatment processes to meet the CCPP conditions required immediately before the number of incoming capital to Water Distribution and Water Treatment Process. First, because of the low solubility in water characteristic of the previous stage of slaked lime and carbon dioxide gas introduced into the calcium hydroxide calcium hardness of the product by adjusting the hardness of calcium to meet the conditions required CCPP have been left undissolved The fine particles may cause turbidity. Such fine particles are precipitated after the coagulation process through the process, the use of activated carbon and filtered while the process is naturally resolve turbidity problem. And the pH of the water is raised by the injection of calcium hydroxide since it is possible to decrease the cohesive effect of the flocculating agent is controlled the pH by injecting a carbon dioxide gas. Thus calcium hardness control is maintained without change until just before the water supply pipe network flows. In the previous step, there is the jeongsuji finally adjusting the pH and alkalinity to CCPP to meet the conditions, the use of soda ash and the carbon dioxide gas that does not cause a turbidity problem. ; Water pipes, slaked lime, carbon dioxide, soda ash, calcium hardness, alkalinity, pH, constant process, caustic soda, corrosion index (CCPP)
