219 Figure 57.: ARTI Compact biogas plant scheme (gasholder empty <strong>and</strong> gas - filled ) The effective volume of the digester is approximately 850l, given by the dimension of the 1000l-water tank (inner radius: 51.5cm) <strong>and</strong> the position of the overflow-pipe (1.04 m above ground level ) . The total surface area of the digester (0.83m 2 ) is covered by roughly 0.65m 2 (78%), in other words the gas released through 22% of the digester surface is lost to the atmosphere without utilization. The usable gas volume of the 750 l - gasholder is 400l. The Hydraulic Retention Time (HRT) suggested by ARTI-TZ, which describes the ratio of the reactor volume (0.85m 3 ) to the f low rate of t he influent substrate (0.02m 3 /day) , is 42.5 days. The seeming lyrather long period of time that digester liquid spends in the reactor is justified by the appearances of sinking <strong>and</strong> floating layers. (Riuji., 2009)
220 Since ARTI-TZ started disseminating CBS in November 2006 until November 2008, 31 ARTI Compact biogas units have been installed in Tanzania <strong>and</strong> Ug<strong>and</strong>a (Table.13) (Table 13).: Household AD installations in Tanzania <strong>and</strong> Ug<strong>and</strong>a 12.3. Chinas household anaerobic digesters China is a country of 1.3 billion people <strong>and</strong> almost 97% live in villages. The most common waste found there are: sweet potato vines, human wastes, animal wastes, <strong>and</strong> food waste. Nowadays in China operate more than 5000000 household anaerobic digesters. These digesters produce biogas (Picture 72.) essential for each house <strong>and</strong> fertilizer also essential in agriculture. Simple composting systems are also used for processing waste.
