WASTEWATERS FROM FERMENTATION INDUSTRIES

As we have discussed earlier although the traditional roots of fermentation lies in food and beverage fermentations, with modern industrial fermentations it encompasses other products such as organic chemicals, antibiotics and even vaccines. The key point in all these diverse types of fermentations are that they are all organic based and depends on microorganisms to carry out the transformations process. Secondly, these industrial fermentations are carried out intensively on a large scale to produce high volume of products

In all these fermentation industries it is unavoidable that huge amounts of wastewaters are generated within a small area, that is the fermentation plants. The source of these wastewaters are at various points of the fermentation activities right from upstream to downstream activities. Usually included in the fermentation wastewaters are:
1 Raw materials or fermentation stocks
2 End products of fermentation
3 The washing and cleaning components
4 Microbial cells and its products

The type and concentration of the fermentation waste waters of course depends very much on the type of fermentation carried out. But generally the waste waters have very high pollution load in terms of BOD and COD, high solids and very colored.

The additional physical characteristics of wastewater often associated are high temperature and even ph differences

The wastewaters from fermentation industries are usually generated in high volumes and with fluctuations in flow variations as the function of production

All these factors usually complicate the treatment option of the wastewaters
