Effect of abattoir waste on the physicochemical and bacteriological qualities of new-artisan river in Enugu, Nigeria

Abstract

The effects of abattoir wastewater pollution at New Artisan River in New Artisan, Enugu East, Enugu State of Nigeria were investigated. The study involved the collection of water samples at the designated points from the New Artisan River where the abattoir wastewaters are discharged. The physical, chemical and bacteriological analyses of the wastewater samples were conducted using standard analytical methods. Results of the laboratory tests were analyzed using statistical tests. The results obtained were compared with World Health Organization (WHO) and other international standards. The results obtained were pH; 6.54 at 25.0 o C, biochemical oxygen demand (BOD); 5009(mg/L),chemical oxygen demand (COD); 3820(mg/L), total suspended solids (TSS); 97.3(mg/L) , total dissolved solids (TDS); 56.7(mg/L) , conductivity; 113(µS/cm) , , dissolved oxygen (DO); 8.60(mg/L) , turbidity; 24.0(NTU), colour; 117(Pt-Co), total solids (TS); 154(mg/L), total hardness (TH); 42.0(mg/L), calcium; 10.4(mg/L), coliforms; 9000(cfu/ml) and E-coli; 7500(cfu/ml) . Analyses of the results showed that the samples were highly polluted. Hence, appropriate measures are herein suggested as a means to control pollution discharge in New-Artisan River in order to enhance the quality of human and aquatic life

Efficiency of Some Chemical Reagents with Ultrafiltration System in the treatment of Abattoir Wastewater

“…The BOD concentration decreased after treatment for both S2 and S3 with a value of 2.08 and 0.68 mg/L respectively. A drastic reduction in slaughter house wastewater after treated using ultrafiltration method was also reported by Asibor (2020), Eze and Eze (2018) and Yordanov (2010). The BOD values for the treated water were below the maximum acceptable limit as illustrated in Table 1.…”

Compliance Monitoring of Microbiological and Physicochemical Parameters of Abattoirs’ Effluents Discharged into Water Bodies in Owerri, Nigeria

“…Abattoir industries generate a lot of wastewater and these eventually find their way into the environment. In many states in Nigeria, facilities for the treatment of abattoir effluents are lacking [2]. A limited or complete absence of treatment facilities for abattoir effluents results in the released of a substantial amount of abattoir effluents into receiving streams, lakes, and rivers.…”

Potential ecological risk assessment of heavy metals associated with abattoir liquid waste: A narrative and systematic review

“…Blood not recovered, viscera, gut content, bone, urine, excrement, soft tissue destroyed during trimming and cutting, dissolved solids, solubilized fat, and cleaning and sanitizing agents are among the constituents of abattoir liquid waste [ [8] , [9] , [10] ]. High levels of salts, phosphates, nitrates, heavy metals, bacteria, viruses, and other microbes are frequently associated with abattoir liquid waste [ 11 ].…”
