Foam in the booth can interfere with booth balance and impact the painting operation. Foam in the pit/sump can lead to sludge removal problems. Foam getting out the stacks can lead to paint deposits on surfaces outside the plant. Sources of foam are many – but a few include high dissolved and suspended solids, increased organic loading, solvent dumps, chemical treatment that is improper or out of control, and highly aerated situations, such as pump cavitation. Galaxy understands the sources of foam and also has products to control it.
