The ROI case for automatic dosing is not one number: it is chemical waste, labour hours, compliance risk and equipment life moving together.
The Operating Reality
A plant comparing a manual dosing round against an automatic skid on the same loop, over a one-year horizon.
Why It Matters
Manual dosing wastes chemical through overfeed and loses protection through underfeed. Both cost money, but only the first is visible on a purchase order.
How It Works in Practice
- Chemical waste falls from a typical 15-25% to 2% or less; on large loops reported savings exceed RMB 800,000 per year.
- Inspection rounds drop from about 4 per day to roughly 0.2 per day, with manual handling of concentrated chemical largely removed.
- Concentration compliance rises from 65-80% to 98% or better, and anti-corrosion performance is reported to improve several-fold.
- Operation and maintenance cost is reported to fall by 40-70%, with labour requirements reduced by about 90%.
Selection Checklist
- Choose the control signal (pH, ORP, conductivity or flow-proportional) before sizing equipment.
- Size the metering pump to the working dose with margin, not to peak demand.
- Confirm wetted-part compatibility for every chemical to be fed.
- Require leak detection, dry-running protection and containment in the installation.
- Plan integration with PLC, DCS or remote telemetry from the start.
