Two papers: 1- Research Report. 2- Source Assessment. And they are both about Utilization Of Sludge Gas - Essay Example

To address these challenges, proper utilization of sludge gas is vital. The utilization of sludge gas is one of the interesting developments in the modern sewage treatment systems. Sludge has being converted to fuel using various technologies such as “low temperature carbonization technology”, which converts the raw sludge to coal. The utilization of sludge has enabled many companies to have cheap environmentally friendly source of energy, reducing their operational costs. According to Fuhrman (1097), the sludge gas provides energy close to 900 B.t.u per capita per day.

The decisions to choose the type of sewage treatment system for a society depend on the potential benefits the project has to the society and the costs involved (Yoder 12). There are various methods used in the treatment of sludge. The first method is sewage sludge incineration. This process involves drying the sewage sludge to a moisture content of about 20% in the drier and sending the content to a fluidized –bed gasifier, where after various processes biogas is produced (Yoder 23). With advancement in technology the utilization of sludge has increased.

It is important to note that, a well regulated digestion of sludge in terms of temperate is one of the most effective ways of producing gas, which can sustain requisite digestion temperatures and production of dried sludge within a short period. The short duration helps in reducing the production costs making the process more viable economically (Fuhrman, 1087). The use of sludge gas has reduced the cost energy considerably. For instance, a small power plant in the state of Indiana, by using sludge gas the cost of electricity has dropped to $0.

0047 per kilowatt –hour (Kwh) (Heckling 132).This has helped the local community economically by having low electricity bills. In addition; sludge gas is an effective use of waste, as it conserves natural resources by putting
