The "Cooling Crystallization Method" is one of the methods for recovering sulfuric acid and ferrous sulfate by cooling the wastewater discharged from the sulfuric acid pickling tank and separating them. Since it does not use steam, it is possible to reduce running costs. Our company concentrates wastewater (industrial waste) from acids such as sulfuric acid, hydrochloric acid, nitric acid, and boric acid that can no longer be reused, and recovers reusable acids through processes like crystallization and dialysis, thereby reducing the volume of wastewater and lowering the disposal costs of industrial waste. 【Features】 ■ Cools wastewater and separates and recovers sulfuric acid and ferrous sulfate ■ Does not use steam ■ Possible to reduce running costs ■ Recovered sulfuric acid is reused in the pickling tank *For more details, please refer to the PDF document or feel free to contact us.

The "Demikuron" is a high-performance mist eliminator that performs gas-liquid separation of exhaust gases containing mist and dust. To meet the diverse needs of our users, we offer a variety of element types. We manufacture models ranging from small units with a gas capacity of 3 Nm3/H (approximately 240φ) to large units primarily for thermal power plants with a capacity of over 2,740,000 N,m3/H (24mW×8mH). 【Features】 <K-201> ■ Standard type with low pressure loss and resistance to clogging ■ Suitable for gases containing dust ■ In cases where pressure loss is a concern or when the mist volume is significantly high, it can be used alone or in combination with models such as K-170A and K-301. *For more details, please refer to the PDF materials or feel free to contact us.
