Flotation in wastewater reuse is caused by the fluctuating flow rate of the alkali pump
Thread Content
Please ask； In wastewater reuse, flocculation occurs due to fluctuations in the flow rate of the alkali addition pump. Initially, the pump was set to operate automatically, and when the flow rate decreased, it was switched to manual mode, but the problem persisted. This led to fluctuations in the pH value of the water downstream. It is likely that the issue lies with the pump; I’m asking if anyone has encountered a similar situation and how it was resolved Thank you
Manual addition means adding it by hand? Should the pump be started and stopped manually for dosing? If it’s the former, there should be significant fluctuations in water quality ； In the case of the latter, check what type of pump it is; if it’s a diaphragm metering pump, pay close attention to the diaphragm, as it may need to be replaced.
What exactly is the process? It seems like you didn’t explain it clearly.
