Kiyomaru-kun is primarily made from volcanic soil natural siliceous materials unique to southern Kyushu, and it is a neutral, natural inorganic material that does not burden the environment, serving as a safe and reliable water purification agent (coagulant). Thanks to Kiyomaru-kun's high coagulation ability and the rapid coagulation reaction and sedimentation speed, it has become possible to safely and quickly purify various industrial wastewater (such as wastewater from vehicle painting booths) that conventional coagulants could not adequately address. It aims to simplify the treatment process, reduce costs, and promote reuse.

We would like to introduce some case studies of our product "Chelate Marine." By installing it in a garden pond in Hiroshima Prefecture, we achieved a change in water quality from COD: 20ppm to COD: 12ppm after three months. Additionally, in a clam farming facility, there was an improvement in the survival rate of clams. This product not only improves water quality but also demonstrates excellent effects on soil improvement. 【Case Studies (Partial)】 ■ Shobara City, Hiroshima Prefecture Pond: Reduction of COD ■ Kyobashi River Floodplain, Hiroshima Prefecture: Improvement of sludge ■ Fuchu Town, Hiroshima Prefecture Side Ditch: Reduction of unpleasant odors ■ Hatsukaichi City and Onomichi City, Hiroshima Prefecture Coast: Improvement of sludge, increase in shellfish ■ Akituk Town, Hiroshima Prefecture Oyster Farm: Promotion of oyster growth *For more details, please refer to the PDF document or feel free to contact us.

"Kireto Marine" is a water quality and sediment purification material that has been proven to release iron and silicon, promote the growth of phytoplankton, suppress eutrophication, decompose sludge, and purify water quality. The chelating agent in its composition has a molecular structure resembling crab claws. The claw-like parts bind to iron ions, enveloping them. This prevents the oxidation and precipitation of iron ions. 【Mechanism】 <Water Quality Improvement> ■ Iron ions and silicon released from the sediment are absorbed by diatoms in the water, leading to an increase in diatom populations. ■ The increased diatoms absorb nitrogen and phosphorus from the water, resulting in a decrease in nitrogen and phosphorus levels. ■ Additionally, iron ions bind with phosphorus in the water, reducing phosphorus levels. *For more details, please refer to the PDF document or feel free to contact us.

"Kiyomaru-kun OIL" is a natural inorganic coagulant suitable for treating high-concentration oily wastewater, such as cutting and grinding oils, and high COD wastewater. The speed of coagulation is overwhelming, and it can remove fine suspended solids and heavy metals that other coagulants cannot handle. The flocs formed are large and have low viscosity, making dewatering treatment easy and reducing the waste disposal of the coagulants. "Kiyomaru-kun" was featured in the Nikkan Kogyo Shimbun on September 11 (Wednesday). ~ A case study on wastewater treatment at Nissan Motor's Yokohama plant was included ~ [Features] ■ Overwhelming coagulation power ■ Capable of removing fine suspended solids and heavy metals ■ Usable for alkaline wastewater (pH around 10-13) ■ Easy to adjust the amount of addition ■ The flocs formed are large and have low viscosity, making dewatering treatment easy *For more details, please refer to the PDF document or feel free to contact us.

"Kiyomaru-kun ZP" is a natural inorganic coagulant made primarily from silicate (volcanic ash). It is suitable for the treatment of wastewater from tools such as brushes and rollers used in painting, as well as for circulating wastewater in paint booths. The recommended dosage is between 500 to 2,500 ppm. 【Features】 ■ Overwhelming coagulation power ■ Capable of coagulating fine suspended solids ■ Can generally be used without pH adjustment for weakly acidic to alkaline wastewater ■ Easy to adjust the dosage ■ The formed flocs are large and have low viscosity, making dewatering treatment easy *For more details, please refer to the PDF document or feel free to contact us.

"Kiyomaru-kun T" is a natural inorganic coagulant suitable for the treatment of cement wastewater. Adjusting the dosage is easy, so it can be used without specialized knowledge or skills. It is suitable for treating wastewater generated during ready-mixed concrete washing and high COD wastewater generated in food factories. 【Features】 ■ Overwhelming coagulation power ■ Capable of coagulating fine suspended solids ■ Usable even at high pH ■ Can be used for alkaline wastewater with a pH of about 10 to 13 ■ The formed flocs are large and have low viscosity, making dewatering treatment easy *For more details, please refer to the PDF materials or feel free to contact us.

"Kiyomaru-kun OIL" is a natural inorganic coagulant suitable for treating high-concentration oily wastewater, such as cutting and grinding oils, and high COD wastewater. The speed of coagulation is overwhelming, and it is capable of removing fine suspended solids and heavy metals that other coagulants cannot handle. The flocs formed are large and have low viscosity, making dewatering treatment easy, which reduces the amount of waste for disposal. 【Features】 ■ Outstanding coagulation power ■ Capable of removing fine suspended solids and heavy metals ■ Usable for alkaline wastewater (pH around 10 to 13) ■ Easy to adjust the amount of addition ■ The large flocs formed have low viscosity, making dewatering treatment easy *For more details, please refer to the PDF document or feel free to contact us.
