Effluent treatment sludge digestion

The above-cited studies demonstrate the performance of a particular unit system for the treatment of specific type of waste stream. A particular unit system alone may not be able to treat the wastewater to a level of effluent standard prescribed for its safe disposal. Hence a number of pretreatments, such as screening, sedimentation, equalization, and neutralization, and post-treatment units such as secondary sedimentation, sludge thickening, digestion and disposal, disinfection, and so on, are extremely important for complete treatment. The effluent treatment and disposal facilities adopted by various types of pharmaceutical industries are described in the following sections. 

This chapter presents an overview of sample treatment procedures [e.g., decomposition, digestion, mineralization, oxidation, ultraviolet (UV) decomposition, and ozonation] and discusses a range of analytical techniques for the mineralization of natural aquatic systems. Other samples, such as effluents and sewage sludge, are beyond the scope of this contribution and will not be discussed here.
