Process Evaluation of a Domestic Biogas Digester

Kenya Domestic Biogas User Survey

Biogas stripping of ammonia from fresh digestate from a food waste digester.

The efficiency of ammonia removal from fresh source-segregated domestic food waste digestate using biogas as a stripping agent was studied in batch experiments at 35, 55 and 70°C, at gas flow rates of 0.125 and 0.250Lbiogasmin(-1)L(-1)digestate with and without pH adjustment. Higher temperatures and alkaline conditions were required for effective ammonia removal, and at 35°C with or without pH ...

A Process Evaluation of the Clark County Domestic Violence Court

• The Clark County Domestic Violence Court has improved the County's ability to deal with domestic violence perpetrators and victims. • Given the apparent increase in domestic violence cases in Clark County there may be a need to allocate additional resources to the court. • There is a need to conduct an outcome evaluation of the Clark County Domestic Violence Court, with a specific focus on th...

The development and evaluation of a portable polyethylene biogas reactor

Several factors can influence the process of biogas production. The type of reactor is one of the key factors that influence biogas production. Therefore, the aim of this study was to construct a portable horizontal polyethylene-based biogas reactor. In addition, the performance of the developed biogas reactor was tested through digestion of cow manure. The experiments were carried out in Mashh...

Microbial community structure in a biogas digester utilizing the marine energy crop Saccharina latissima

Seaweed is a highly attractive marine crop for the production of biofuels, due to its rapid growth rate as well as high polysaccharide and low lignin content. One appealing exploitation route is the production of biogas by anaerobic digestion. Interestingly, despite the compositional differences between seaweed and lignocellulosic biomass, available data indicate that conditions and inocula tra...
