Rinse Tank Design

Description

Use the minimum size rinse tank the parts fit in, and use that size for the entire plating line
Place the water inlet and discharge points of the tank at opposite positions in the tank to avoid short-circuiting
Use a flow distributor or sprayer to feed the rinse water evenly
Use air agitation, mechanical mixing, or other means of turbulence to provide agitation
Use spray rinsing for flat surfaced parts
Use ultrasonics where applicable (e.g. parts with small recesses)

Provides for fast removal of dragout from the part
Completely disperses dragout throughout the rinse tank
Reduces rinsing time
Concentration of contaminants left on part after rinsing is minimized for a given flow rate
