ダイワ工業 List of Products and Services

"Daiwa Ace" is a filtration system that uses floating filter media made from a special foamed resin, employing a floating layer method. By adjusting the filtration speed and contact time, it achieves two functions in one unit: precise filtration aimed at removing algae and biological membrane filtration aimed at improving water quality. Backwashing is performed using aeration with air, allowing for high flow rates while minimizing clogging, making it capable of handling large volumes of water treatment. Please feel free to contact us when needed. 【Features】 ■ Uses floating filter media made of foamed resin (upward flow type) ■ Backwashing is performed using aeration with air ■ Large contact area per unit volume ■ Capable of handling a wide range of water treatment including biological and precise filtration ■ Only the worn-out filter media is replenished, no need for complete media replacement *For more details, please refer to the PDF document or feel free to contact us.

The "Daiwa Ace (Biological Membrane Treatment)" is a high-performance and compact filtration system that fully utilizes the water purification capabilities of microorganisms. It uses foamed resin as a carrier for the microorganisms, and the filter material is irregularly shaped with a large surface area, allowing it to retain a significant number of microorganisms, making it possible to operate under high BOD volumetric loads. Additionally, it ensures efficient contact between the biofilm and water, allowing for a space-saving facility design. 【Features】 ■ As a floating filter material, it can be backwashed with air, resulting in less backwash water usage. ■ 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 with sand filtration. *For more details, please refer to the PDF document or feel free to contact us.

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, resulting in efficient water contact, which leads to a high capture efficiency of suspended solids (SS) and allows for a space-saving facility. 【Features】 ■ As it uses floating filter media, backwashing with air is possible, resulting in less backwash water usage. ■ 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 with sand filtration. *For more details, please refer to the PDF document or feel free to contact us.

The "Daiwa Ace (Biofilm and Precision Filtration System)" is a high-performance and compact filtration system capable of processing 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 experience issues such as 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.
