Biesterfeld Spezialchemie GmbH offers highly effective and versatile defoamers which can be used as supplied or further diluted with water. The yeast nutrient complex and enzyme blend supply complete macro and micronutrients and a comprehensive environmental package. With regard to the pharmaceutical industry, it is clear that in many applications a fast and effective antifoaming agent is needed to prevent uncontrolled foaming and to maintain smooth and efficient processes. Defoamers eliminate existing foam, while anti-foamers prevent the formation of more foam. Duitschaever, C.L., Buteau, C, and Kamel, B.S. Also presented is a simple model, which simulates foam growth as functions of defoamer concentration, air hold-up, reactor volume and air flow rate. The low surface tension of the antifoam droplets enables the silicone to persistently flow into adjacent foam films and continue breaking them down for repeated antifoaming action - and longer intervals between antifoam replenishment.
