Start with the liquid path
Wet particulate scrubbers transfer particles from the gas into a liquid [2]. Use the site's process diagram to identify the liquid source, pump, contacting section, return and any purge or makeup stream. A tank level reading alone tells little about the amount of liquid reaching the contact section.
Pair flow with operating observations
Record the approved flow measurement point, instrument units, pump state and relevant valve positions. EPA identifies inadequate liquid flow and plugged nozzles as operating problems [2]. If the reading changes after a maintenance event, preserve the before-and-after setup and ask which section should be checked first.
Document the receiving stream
Separate the circulation loop from the facility's liquid and solids treatment responsibility. Define where bleed or spent liquid is measured and who accepts it downstream. This applies the source site's performance-review approach [1] to the actual liquid circuit. Ask for approved operating limits and treatment requirements for the installed process.
FAQ. Can adding makeup water resolve low supply flow?
The cause must be identified from the liquid path and measurements. Check makeup and delivered flow as separate quantities.
