Requirement of Outdoor Water Filtration System

Presently, outdoor water filtration (OWF) system becomes one of home appliances that is a must-have for every house in Malaysia. Even though the tap water is a guarantee can be consumed directly, Malaysians still need the appliances. These home appliances become popular nowadays, however the requirement of the OWF is never determined. This study focuses on OWF system which improves quality of water from the plant treatment at point of entry before it gets to consumers. The purpose of this study was to understand qualitatively the requirement of OWF system through awareness of the consumers. In addition, residual chlorine was also measured to determine the performance of the system. Seven houses that have been using OWF were asked on their awareness on the technology used in their system and mostly said they knew the technology used. However, they are less aware on types of filter media and water parameter that are related to quality of effluent water. Based on the measurement of residual chlorine, the percentage removal after the system was in the range of 76% to 96%. This high removal was reduced the chlorine concentration far below the recommended, thus the safety of water effluent is uncertain. This study shows that requirement of using the system can still be disputed and therefore the large number of sample may require for further study to obtain the real need of OWF system in Malaysia.
