Research Abstract

New type of water purification facility was constructed in Amagasaki Canal in 2012. The facility was consisted with three type purification technologies and attendance of people who picked up nutrient with marine algae and used it for compost. We evaluated its performance and ESD's effect to kid's parents. As a result, we observed water purification capacity rate was 69% of nitrogen in summer daytime. We also carried out a field experiment for increasing purification capacity in nighttime using LED and we estimate the distance of installation interval of LED in algae channel. ESD was very effective and 37% of children's parents changed their mind to join the purification activities. According to questionnaire, there are two reasons why the parents changed their mind; effect of nutrient pick up and the activity regarded as a good chance to develop a parental relationship. This results mean the facility have a function not only water purification but also develop good human relationship.
