Powering the Popularization of "BOD10" Small-scale Johkasou

NIKKO is dedicated to contributing to environmental improvement. We drove the promotion of BOD10 advanced treatment Johkasou for household use.
BOD (Biochemical Oxygen Demand)
BOD is the amount of oxygen required for microorganisms to break down organic matter contained within water. It is the most widely used contamination index. The larger the value, the higher the water contamination level.
