Biogas Production Using Water Hyacinth
(Eicchornia crassipes) for Electricity
Generation in Kenya
2. Methods and Data Sources
Experimental Set up and Design
A biogas plant consisting of a 6 m3 tubular enclosed in Ultra Violet (UV) screen house and cleaning accessories
was installed at Jomo Kenyatta University of Agriculture and Technology, Kenya. Water hyacinth/cow dung
blend (1500 kg) was fed into the digester and allowed to generate gas. Temperature, pH, gas yield and gas compositions
were determined for a period of twelve months. The digester was installed with three sample collection
points. Samples were collected to monitor changes. All parameters were analyzed using standard procedures
[12]. A similar experiment was conducted with cow dung as feed to serve as control for the experiment. The
biogas production process is illustrated in Figure 1.
