Waste Management of Seafood Processing Effluents, Hadhramout Governorate, Yemen

Wastewater samples were collected from the Hadhramout Governorate/Yemen. Ten wastewater samples were collected from the biggest three fish canning factories in Hadhramout Governorate/Yemen (Tuna for Canning Packing Fishing Factory, AL Mukalla fish canning factory and Sabaa fishing factory). During this study, special precautions were taken to avoid samples contamination during collection, transportation, and preservation and laboratory analyses. The three bacteria isolates (Pseudomonas sp. Y1, Pseudomonas sp. Y2, Hafnia sp. Y) from wastewater fish canning showed a good results in pollutants removal as compared to the 45 isolated species bacteria. Results of the present study proved the biotechnological importance and advantages of using the tested bacteria for wastewater treatment where promising removal of the investigated contaminants were achieved in a short time. For organic matter removal, the highest achieved OOM, BOD5 and COD RE recorded 79, 74 and 73% achieved by ponds, respectively. For oil and grease the highest achieved FOG RE recorded 87% and was achieved by ponds. Removal of wastewater pollutants, where the results showed laboratory based on the concentration of pollutants before and after the treatment occurs, the removal of organic matter (OOM, BOD, and COD), oil and grease at rates of 70%, 60%, 50% and 85% respectively by treatment ponds. Pond, which was shown to have high potential for use in wastewater treatment, was tested for its ability to treat the wastewater sample. It was found that waste decomposition by natural microorganisms already present in the wastewater. Finally, our study indicates that strains of Pseudomonas and Hafnia alvei isolated from wastewater samples of fish canning industry of Hadramout, Yemen and ponds method were able to be the pollutants that these strains could be efficient pollutants removal.
