| Abstract |
The current study aims to design and manufacture a simple biogas unit suitable for the small-scale holder in the remote areas of Egypt, to produce biogas from leftover food and kitchen waste; the hydraulic model of biogas system was selected as a simple model for biogas digester. The biogas unit was fabricated from simple material with a total capacity of 1m3. The results showed that the ambient temperature was ranged from 32 oC to 39 oC, digester temperature was ranged from 30 oC to 35 oC, pH was ranged from 7 to 7.3 and C:N ratio was ranged from 15~28:1, that indicates to these conditions were suitable for completing the fermentation process and biogas production. The total solid concentration (TSC) and fermentation time have an effect on biogas yield and CH4 content, where the biogas yield was increased with the increasing of TSC. The highest biogas yield was obtained under TSC 14% in the week number 11th, and the biogas yield has limited increasing under the same TSC and different fermentation time. The fabricated unit was succeeded to produce economic biogas with CH4 content 58% and 62% from leftover food and kitchen waste mixed with caw manures, respectively. The highest weekly biogas yield was 2.75 m3 under TSC 14% with an average of 0.4 m3 per days, it could be covering the biogas needs for 2 people, thus, this unit could be recommended for farmers families in the remote areas as a simple biogas technology to produce biogas from their kitchen wastes..
