Current Progress in Biogas and Bio Chemicals Production with Effluent Treatment

The major category of waste generated worldwide every day is wastewater. Treatment of waste water is one of the all-time growing topics. Anaerobic digestion is a major process in the current scenario which is keeping up the sustainable development process without creating any waste and converting wastewater into useful from a small scale to a large scale cost effectively. The presence of organic waste in water contributes to the growth of microbes and the reduction of DO (dissolved Oxygen). As wastewater is produced by both households and industries so, having a great range of food for anaerobic bacteria helps them to produce biogas. In the present and in the coming future the volume of waste is not going to reduce at any cost because whatever we consume gives out waste so often, and having a process of using “waste to best” is much needed, and the solution is in front of us that is anaerobic friends and their process of digestion anaerobically. With a combination of 13 manure-based digesters, Washington, Oregon, and Idaho are seeing an increase in on-farm anaerobic digestion projects. There are other agricultural digester initiatives in the works. Several digesters that are being built primarily to treat food waste streams will soon be located in the Northwest. These include Green Lane Energy outside of Junction City, Oregon, and Columbia Biogas in Portland, Oregon. Some case studies on the combined setup of effluent treatment and agriculture or cattle farm waste generation are discussed in this chapter. Several of these recent ongoing projects in the Northwest region are highlighted in this chapter.
