Abstract
This study focused on the investigation of bio treatment of brewery wastewater using engineered micro organisms like Hycura. Brewery wastewater was treated in a 10L tank over a 5 day period with Hycura loadings of 0.05 g/L. The wastewater chemical oxygen demand (COD), biological oxygen demand (BOD), pH, total suspended solids (TSS), total Kjeldahl nitrogen (TKN) and total phosphates (TP) were measured using standard methods on a daily basis. The ph of the brewery waste changed from alkaline to neutral during the treatment process whilst the COD reduced by 87%, BOD by 88%, TSS by 94%, TKN by 68% and TP by 81%. The effective bio treatment of the brewery wastewater is attributed to the metabolism of Hycura.
