ABSTRACT
This chapter provides with an idea about how the modern scenario of animal production is going to change over time after decade and what effect it will be exerting on the world with respect to its hazards and wastewater generation for its maintenance. Farm animals are fed directly by cereals feed, from which a high proportion is finally released into the environment with or without prior treatment. Treatment technologies can play a vital role in the management of livestock manure by providing a more flexible approach to land spreading and by resolving specific problems such as malodors or ammonia emissions. Such treatments are based on biological and physical processes, along with the selective use of chemical additives. Although the integration of biological and advanced treatment processes usually yields satisfactory effluents, in some cases, the final waste water may cause harmful effects on the aquatic environment.
