The intelligent carbon dioxide dosing equipment consists of a gas mass flowmeter, a pneumatic membrane regulating valve, a solenoid valve, a mixer, a pressure gauge, a safety valve, a PH meter, a pressure transmitter, and an intelligent control system. It can be connected to a variety of communication modes to achieve remote monitoring, fully automatic operation and other functions. The system reacts with carbon dioxide and water to generate carbonic acid and neutralize the alkaline substances in the water to achieve the effect of reducing the pH value of raw water. Compared with the traditional addition of chemical reagents to adjust the PH, it not only saves the amount of coagulant, but also reduces sludge production; it is safer, greener and healthier, and is in line with the “green and low-carbon” development trend of water plants in the future.
System purpose: Reduce pH value and improve water quality
Principle of action: The resulting carbonic acid solution reaches the dosing point through the dosing device under a certain pressure, and reacts with the alkaline substances in the water to neutralize it.
