It is a water quality purification material that is friendly to aquatic environments (aquatic organisms) made from natural ingredients. (Registered in NETIS.)
The "Natural Coagulant Doronpa Series" is a very eco-friendly water purification agent for the ecosystem of the environment in which it is used. Since it is primarily made from natural clay, there is also a track record of reusing the sediment. Therefore, safe and low-cost water treatment can be achieved without processing sludge as industrial waste. Additionally, a purification project for the moat of Himeji Castle, a UNESCO World Heritage Site and national treasure, was carried out using the Doronpa series (from March to May 2008).
