Abstract

A settling pond containing wastewater coming from a private piggery and its surrounding lavatories was analyzed for possible utilization as irrigation and water and media for culturing fish. The following parameters were determined: temperature, pH, dissolved oxygen (DO), biological oxygen demands (BOD), chemical oxygen demand (COD), hardness and total solids. The Aside modification of the Winkler Method was followed for determining the DO, Permanganate Method for the COD and dilution technique for the BOD. Hardness was calculated through titration of ethylenediamine tetra acetic acid.

The statistical analysis of the data for DO, BOD, COD, hardness and total solids showed that the source of variation were significant at 1% level.

The results showed that the wastewater can be possibly utilized as irrigation water, but not as media for culturing fish. The higher concentration of calcium and magnesium ions and organic materials in the wastewater compared to that of the source water makes the wastewater a better irrigation water. However, the wastewater contains higher level of oxygen demanding wastes leading to inappropriate use as media for culturing fish.
