Water Quality Assessment And The Design Of A Chlorine Disinfectant System For Fuoye, Ikole Campus

ABSTRACT

Disinfection of water is a crucial step in the treatment of water in order to obtain clean drinking water. The use of water disinfection as a public health measure reduces the spread of diseases. This research paper examines water quality assessment of ground and surface water samples obtained from lkole campus of the Federal University Oye-Ekiti (FUOYE). The obtained stream water was tagged Sample A, and the ground water (borehole) was tagged Sample B. These two constitute major source of water in the campus. Initial water quality assessment of the parameters that effect chlorine decay was done and compared with World Health Organization (WHO) and Nigeria Standard for Drinking Water Quality (NSDWQ) standard for chlorination. Examples of such parameter includes: temperature, pH, turbidity, coliform count etc. Predetermined initial concentration of 1.0 to 3 mg/I was added to different Jar and the contact time required to achieve a residual level of 0.2 to 5 mg/I was determined. Apart from the Jar test other chlorination related experiments done includes supernatant turbidity, chlorine decay and demand distribution. This study indicates sample A as having slower decay rate than sample B. This presents a chlorination assessment of FUOYE water useful for the development of a chlorine disinfection system for her use. Continuous monitoring of the water quality is necessary after the quality assessment is done resulting to water management. It was concluded that results from this work on laboratory conducted on surface water showed that it requires further treatment before it can be suitable for drinking water. It was recommended that there should be continuous testing of water quality composition of surface and groundwater in FUOYE Ikole campus water. Chlorine is highly recommended in terms of cost effectiveness (i.e. lower in cost) and readily available because of its wide array benefits which cannot be provided by any other disinfectant which includes ozone, ultraviolet radiation etc.
