  ABSTRACT

The present study was planned with the objectives to study physico-chemical characters, microbial analysis and effect of alum treatment on effluent water of unorganized poultry dressing units. A total of six (6) poultry dressing units were selected from Parbhani city for sample collection on weekly basis for a period of eight (8) weeks. Physico-chemical characters colour, odour, total solids (TS), turbidity,hardness, pH, BOD and COD of effluent water were studied Micr.obial analysis was done in relation to MPN for coliform, Staphylococcus sp. and Clostridium sp. screening of the samples. It was observed that 83.33% of effluent water before alum treatment showed red colour and 90.12% of effluent water after treatment showed brown colour. A total of 93.75% samples were positive for offensive odour before treatment and 79.17% of the samples after treatment were unpleasant. A significant (P< 0.05) difference in total solids (TS), turbidity, hardness, pH, BOD and COD were observed among poultry dressing. The mean total solids (TS) of effluent water observed was 3241.67 18.00 mg/L before alum treatment which reduced to 2873.60 18.00 mg/L after alum treatment. The mean turbidity value was 159.420.68 NTU before alum treatment and 104.73 0.68 NTU after alum treatment. The hardness and pH values of effluent differs significantly (P< 0.05) amongst poultry dressing units with 533.85 4.50 mg/L of hardness before alum treatment and 492.29 4.50 mg/L after treatment, pH of 7.08 0.04 before alum treatment and 5.250.04 after alum treatment. The mean BOD and COD values were 152.530.46 mg/L before alum treatment and 95.93 0.46 mg/L after alum treatment and 251.25 2.35 mg/L before and 150.96 2.35 mg/L after alum treatment respectively. The MPN for coliform observed before alum treatment were ranged from 1100 to >2400 MPN per 100 ml before alum treatment which reduced to 29 to 240 MPN per 100 ml after alum treatment. All 48 samples (100.00%) screened resulted into showing presence of Staphylococcus and Clostridium sp. colonies before alum treatment. The percentage of Staphylococcus colonies after alum treatment found was 93.75%. and Clostridium sp. after treatment was 95.83% respectively. Evaluation of poultry dressing unit effluent water as compared to IFC standards in relation to pH, BOD, COD and total coliform bacteria revealed that the effluent showed values of some parameters within limits of guideline values except BOD and total coliform bacterial count. The results concluded that the physical and chemical characters of poultry dressing unit effluent differ significantly (P< 0.05) amongst poultry dressing units and the alum treatment given was effective in removing physical and chemical impurities except BOD, but not effective on microbial parameters.

Key words: Effluent, BOD, Hardness, Turbidity, Poultry dressing units, MPN.
