EXPERIMENTAL STUDY ON THE WATER PURIFICATION OF RIVER IN URBAN REGION USING BAMBOO CHARCOAL

Abstract

 This study was aimed at estimating effectiveness on bamboo charcoal for the water purification of river in urban region. The demonstration experiment in water purification using bamboo charcoal was conducted at a distributary channel of Yota River in Kakogawa River basin. The laboratory experiment in adsorption isotherm for methylene blue and the model experiment on glucose as a constituent of BOD were also conducted. As the results of these experiments, it demonstrated a decrease in SS and BOD in the channel water by passing through bamboo charcoal. In addition, it obtained the Freundlich isotherm for adsorption of methylene blue onto bamboo charcoal. Furthermore, the result of the model experiment suggested the necessary weight of bamboo charcoal for decreasing in BOD in the channel water.
