Construction and Performance Verification of Chlorine Dispenser According to The Quantity of Water

Abstract

The purpose of this study aims to construction and performance verification of the chlorine dispenser according to the quantity of water. Research methodology was divided into 4 parts as follows. Study and collecting data, designing, constructing and testing chlorine dispenser. Data record form was used as a research instrument to collect the information. The data from experiment results were analysed in term of means and percentage.
The chlorine dispenser is 20 cm. wide, 35 cm. long, and 55 cm. high. At has 1 water inlet, 1 chlorine inlet, 1 chlorine outlet, and 1 water outlet. The dispenser consists of microcontroller, flow sensor and a high pressure pump, 4.8 bar, 31 watt. Chlorine dispenser has 2 systems as follows:
1) Dispensing chlorine and water automatically according to the amount of water we need, using send pulse signal to microcontroller in order to calculate the quantity of water and provide the amount of chlorine through a high pressure pump. The chlorine was dispensed correctly according to the amount of water we need. (98.18%) The left - over free chlorine residual was 1.03 ppm.
2) Dispensing chlorine according to the amount of water specified microcontroller was used for dispensing chlorine through high pressure pump. The chlorine was dispensed correctly according to the amount of water specified. (96.50%) The left-over free chlorine residual is 0.52 ppm.
