Abstract:
Antifoam (defoamer) chemicals are a crucial part of many commercial fermentation processes. Reviewed are the types of defoamers and their mode of operation. Also presented is a simple model, which simulates foam growth as functions of defoamer concentration, air hold-up, reactor volume and air flow rate.
