Biogas production by treating sludge of  waste water treatment plants for the generation of electrical and thermal energy with high increase worldwide. Cost savings through sludge treatment/digestion can be over 50 percent. Technical Innovations 2025


Technical Challenges of Producing and Using Biogas
Successfully capturing and using biogas as a fuel source from wastewater sludge has been described as an art as much as a science.Maintaining the bacteria population in the digesters that is needed to breakdown wastewater solids is challenging due to the sensitivity of the bacteria to a number of factors, especially temperature and alkalinity. Variability in the type of sludge, amount of sludge, moisture content, temperature, and other factors can cause a massive die-off of the bacteria and subsequent cessation of methane production. In such cases, the resulting gas emissions will frequently consist of carbon dioxide and odorous hydrogen sulfide. Operator skill and detailed knowledge of the plant are critical factors in successful operations.

Less than 20 percent of the waste water treatment plants to day use and produce biogas,
reduce costs and disposal. But this is fast changing as helmut kaiser consultancy
show in a new 2011 study about biogas worldwide
