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 a proven track record of reusing the sediment. Therefore, water treatment can be achieved safely and at low cost 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 conducted using the Doronpa series (from March to May 2008).

basic information
【Features】 ○ The main raw materials are natural clay minerals and water. ○ Quickly captures pollutants and aggregates rapidly, with strong re-aggregation properties. ○ No chemical agents such as aluminum or iron-based inorganic coagulants or petroleum-derived organic polymer coagulants are used, except for trace amounts of food additives and natural polymers. ○ Completely non-toxic, non-hazardous, and non-corrosive, posing no risk of secondary pollution, making it safe for the environment and human health. ○ The treated water has the same electrical conductivity and pH as the raw water. ○ Due to the main raw material being clay minerals, the stability of the sediment is very high, ensuring safety for the ecosystem even if it accidentally flows into the environment. ○ The aggregated sediment can be reused. ● For more details, please download the catalog or contact us.
