Abstract
In order to ensure environmental protection, wastewater requires treatment before it is discharged into the environment. This research looks to improve the quality of industrial effluent through treatment using natural zeolites. Samples were collected from Biyinzika poultry slaughterhouse and tests were carried out on them. Preliminary tests indicated high COD, BOD, Turbidity, TN and TP values in comparison to the national standards. The high BOD and COD values were attributed to the high organic loading of the effluent from the plant. This therefore meant that secondary treatment was required aside from the existing wastewater treatment system.
The main objective of this research and the design were achieved. The design consists of a secondary treatment system comprising of zeolites located after the initial treatment processes. This will ensure that the effluent is treated to the required standards before discharge.
The use of natural zeolites increased the efficiency of the treatment process. There was a high percentage reduction in all quality i.e. maximum turbidity, BOD, COD, TN and TP with percentage reductions of 75.7%, 81.3%, 90.8%, 64.2% and 89% respectively. All the quality were also treated to the required standards for discharge therefore implying the main objective the research was achieved.
