Abstract

The number of drinking water refill stations (DWRS) was increased rapidly because high of mid-low urban community need to get affordable drinking water. Water treatment methods in DWRS are varying even many DWRS uses more than one disinfection method to increase the effectiveness. The quality of many DWRS productions was reported unstandardized, however not yet the study to evaluate the effects of the water treatment method used. This study aimed to compare the effectiveness of various water treatment methods in DWRS to identify which method is the most effective. The study used a cross-sectional approach conducted in 3 groups of water treatment methods, namely ultraviolet, ultraviolet + ozonization, and a combination of ultraviolet + ozonization + reverse osmosis with each group consisted of 40 DWRS. The survey was conducted in July–September 2017 in Bandung municipality by structured interview. Examination of microbiological parameters of raw and processed drinking water samples using membrane filter method. Water samples from raw water and drinking water from treatment process were taken from each DWRS to be tested for the microbiological parameter by using the membrane filter method. Comparison of the effectiveness was analyzed using the Wilcoxon rank sum test and assessment of log removal reduction. The result showed that there was significantly different in the effectiveness of coliform removal between the three groups. The improvement for controlling and training particularly for the procedure and maintenance of water treatment equipment to the owners/workers in DWRS is urgently needed as the concern of related authority. In conclusion, the water treatment method using ultraviolet is the most effective disinfection method compared to the combination with other methods. The usage of more that one method of water treatment at the same time relate to the lower percentage of the effectiveness compares to the usage of only one method.
