"Sandblasting work" is a process that uses high-pressure air to spray special sand (abrasive) to powerfully remove scale that has adhered to the inside of a boiler. It can clean areas that are unreachable by manual labor without causing any damage to steam pipes or heater tubes in a short period of time. Additionally, since sandblasting is a dry method, there are no concerns about low-temperature corrosion after the work is completed, and there are no issues with wastewater treatment or corrosion occurring after wet method construction. 【Features】 ■ Can be cleaned in a short time ■ No damage to steam pipes or heater tubes ■ Capable of cleaning areas that are unreachable by manual labor ■ No issues with wastewater treatment or corrosion after wet method construction *For more details, please refer to the PDF materials or feel free to contact us.

• Refrigeration units, boilers, cooling towers

The "Daiwa-type BC Automatic Cleaning Device" is an automatic cleaning device that removes adhering scale and slime from inside tubes to maintain the vacuum level of the condenser and the heat transfer rate of the heat exchanger, while also protecting the equipment from corrosion and ensuring the safety of small pipes. It cleans the cooling tubes by moving a dedicated cleaning brush using the flow of cooling water. The dedicated cleaning brush alternates between normal operation and backwashing operation. 【Features】 ■ Improved heat exchange efficiency and reduced fuel costs due to scale removal ■ Extended lifespan of the condenser and reduced replacement costs due to scale removal and corrosion suppression ■ Increased heat exchange efficiency leading to better fuel economy and reduced environmental impact *For more details, please refer to the PDF document or feel free to contact us.

• Water Treatment

The "Daiwa Ace (Biofilm and Precision Filtration System)" is a high-performance and compact filtration system that can handle both biofilm filtration and precision filtration in a single device. It uses a material that is amorphous with a large surface area, providing excellent water contact efficiency. Additionally, by adjusting the filtration speed, it allows for both biofilm filtration and precision filtration. In other words, by installing this product, you can achieve dual processing (biofilm filtration and precision filtration) with one unit. 【Features】 - As it uses floating filtration media, it can be backwashed with air, resulting in less backwash water. - It can be used semi-permanently, leading to less frequent replacements compared to sand filtration. - It does not produce mud balls or channeling phenomena that occur with sand filtration. *For more details, please refer to the PDF materials or feel free to contact us.

• Water Treatment

The "Daiwa Ace (Precision Filtration)" is a high-performance and compact filtration system capable of removing suspended solids (SS). This system is characterized by the use of foamed resin as the filter medium. The filter medium is amorphous and has a large surface area, which allows for efficient contact with water, resulting in a high capture efficiency for debris such as suspended solids (SS), making it suitable for space-saving facilities. 【Features】 ■ Since it uses floating filter media, it can be backwashed with air, resulting in less backwash water usage. ■ It can be used semi-permanently, so it requires less frequent replacement compared to sand filtration. ■ It does not experience issues like mud balls or channeling phenomena that occur with sand filtration. *For more details, please refer to the PDF materials or feel free to contact us.

• Water Treatment

"Daiwa Ace (Biological Membrane Treatment)" is a high-performance and compact filtration system that fully utilizes the water purification capabilities of microorganisms. It employs a foamed resin as the carrier for the microorganisms, and the filter media is amorphous with a large surface area, allowing it to retain a significant number of microorganisms, thus enabling operation under high BOD volumetric loads. Additionally, it allows for efficient contact between the biofilm and water, making it possible to create a space-saving facility. 【Features】 ■ As a floating filter media, it can be backwashed with air, resulting in less backwash water. ■ It can be used semi-permanently, leading to less frequent replacements compared to sand filtration. ■ It does not experience issues such as mud balls or channeling phenomena that occur in sand filtration. *For more details, please refer to the PDF document or feel free to contact us.
