Treating municipal sewage anaerobically results in a clean disposable effluent, biogas and low quantities of biosolids (Lettinga 1995; El-Fadel and Massoud 2001; Mahmoud et al. 2003; Wei et al. 2003; Hospido et al. 2005; Coelho 2006b; USEPA 2013). These are the products that are also promoted by treating wastewater with Hycura (Powell and Lundy 2007). The biosolids produced are in minute quantities as most of them are degraded during the decomposition of the sewage into biogas (El-Fadel and Massoud 2001; USEPA 2013). Anaerobic digestion of sewage has many advantages, which include environmental and economic benefits from the biogas production (Lettinga 1995; El-Fadel and Massoud 2001; Hospido et al. 2005; Coelho 2006a; USEPA 2013). The treated sewage effluent can be used for irrigation purposes or can be disposed of in water bodies depending on the extent of treatment (Manyuchi and Phiri 2013; Muserere et al. 2014). Sewage effluent 22characteristics for use in irrigation and decorative purposes are shown in Table 4.1.
