소결온도와 쌀겨 투입량이 중력식-세라믹 필터의 기공형성과 pH가 다른 원수처리에 미치는 영향평가

The 'safe drinking water' adopted as the 6th topic (Clean Water and Sanitation) of the United Nations' Sustainable Development Goals (SDG) is not only the theme of water but also the human rights, gender equality and education. Among the many researchers and NGOs that have been attempted under the name of appropriate technology, water purifier technology using ceramic filter is a representative solution as household purifier that is very well localized, but scientific review is very limited. In this paper, the effects of changes in the manufacturing conditions on the physical properties and flux of the ceramic filter were evaluated, and the effect of the pH change on the removal capacity of ceramic filter was measured. The experimental results showed that the higher temperature and the larger amount of rice bran dosage, caused the larger flux of the ceramic filter. It was found that the mixing method can increase the flux to the ceramic filter by the dry and the wet mixing method. Also, it was confirmed that the flux was slightly increased as the pH of the raw water was lower.
