Can be used semi-permanently! Compared to sand filtration, it has a lower replacement frequency and reduces maintenance costs.
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.
