Scale forms when dissolved solids exceed what the inhibitor can hold. In an evaporative system that threshold moves all day, so the dose has to move with it.
The Operating Reality
Cooling circuits and RO feed lines dose antiscalant or dispersant continuously, with conductivity-controlled blowdown setting the concentration ceiling.
Why It Matters
A fixed manual dose is either wasteful at low cycles or insufficient at high cycles. Precision dosing holds the threshold dose without the safety margin that manual practice has to add.
How It Works in Practice
- Plunger metering at ±0.5% accuracy with pulse rates above 5000 per minute holds small antiscalant doses repeatable.
- Controller responds to conductivity and pH, so dose follows cycles automatically.
- Twelve chemical classes supported, letting antiscalant and dispersant run from one skid.
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.
