“…Due to the nature of the fruit-canning process, large volumes of water are used in the transportation of the product, washing and rinsing, blanching, retorting and cooling operations (Wayman, 1996). Disposal of cannery wastewaters is often complicated by the seasonal nature of the industry, the presence of suspended solids and particulate organics (Harada et al, 1994), cleaning solutions (most commonly sodium hydroxide), often in formulations with various chelating, softening or surfaceactive additives, nitric and phosphoric acids (Mawson, 1997) and sodium hydroxide (used during peeling of certain fruits and vegetables) in the wastewater.…”

Anaerobic treatment of a highly alkaline fruit-cannery lye-peeling wastewater was investigated, using an upflow anaerobic sludge blanket (UASB) reactor. Only a short initialisation period was required before COD reduction and OLR had stabilised at 85 to 90% and 2.40 kgCOD·m , the COD reduction remained between 85 and 93% and biogas production peaked at 4.1 ℓ·d -1 (63% methane). COD and reactor pH started to decrease after 111 d. Decreases in gas production were observed by Day 102, decreasing to 2. ) within the reactor biomass, leading to inhibition of methanogenesis.
