The Use of Electronic Equipment in Assessing Physicochemical Parameter of Some Sachet Water Samples in Akoko Land of Ondo State, Nigeria
Abstract
Measurement of water parameters such as pH, turbidity, dissolve oxygen, conductivity and temperature were studied to prevent water pollution and reduce water related diseases. Traditional method of water monitoring requires collecting data from various sources manually and samples taken to laboratory for testing and analyzing. In order to save time and money wasted on traditional method, a low cost multi-parameters monitoring system based on wireless network was set up to achieve remote real-time monitoring of water quality of available sachet water in Akoko Local government of Ondo State, Nigeria. The equipment consists of two subsystems: data collection subsystem which consists of monitoring sensors and data management subsystem which accesses and receives data from sensors and displays on liquid crystal display (LCD) to the user. In the equipment solar cells and lithium cells were used for power supply. The dissolved oxygen sensor, pH sensor, temperature sensor, turbidity sensor and conductivity sensor were used to measure and monitor the water quality parameters. The experimental trials were carried out on some important sachet water samples in Akoko land. Various water parameters were assessed and successfully logged into the card. The following results from Physicochemical Parameters shows that all the samples have pH ranged from 6.4 - 7.2, dissolved oxygen ranged 6.4 - 6.8m/l, conductivity ranged from 43.3 - 24µS/cm, temperature ranged from 25.6 - 27.1? and turbidity ranged from 75 - 50 NTU. The results of pH, electric conductivity, temperature, turbidity and dissolved oxygen were conformed within the permissible limit recommended by World Health Organization (WHO), Nigeria Industrial Standard (NIS) and Standard Organization of Nigeria (SON) for human consumption and safe drinking water. Therefore, sachet drinking water in Akoko land is safe for consumption.
