ABSTRACT: This study allowed
us to highlight the level of pollution of a BAYA River water near several poultry
farms and the sizing of an anaerobic digester that will be able to treat chicken
manure from a poultry farm (BRIN FOUNDATION). To evaluate this pollution, the
parameters such as ammonium (NH4+), Phosphate (PO43-), Biochemical Oxygen Demand (DBO5) and Nitrate (NO3-) were determined. For sampling point P1, the concentrations
in mg/L of these parameters are (25.00 ± 4.25), (0.40 ± 0.20), (98.00 ± 6.35) and
(96.00 ± 5.35), respectively. On the other hand, for sampling point P2, the concentrations
in mg/L of these parameters are respectively (33.00 ± 9.05), (0.70 ± 0.12), (123
± 7.13) and (93 ± 7.10). These values indicate a strong organic pollution of the
BAYA River. The determination of the different concentrations of the organic pollution
parameters allowed us to evaluate the degradation and the quality of the water of
the BAYA River water, by the poultry activity. However, considering the physicochemical
properties of the waste (chicken manure), which is the main source of organic pollution,
we have considered an energy recovery through the production of biogas. This requires
the design, sizing, and implementation of an anaerobic digester in a poultry farm.
Therefore, the project would require the construction of an adapted masonry type
anaerobic digester with a capacity of 10 m3.
