The use of fine sand has enabled automatic backwashing and unmanned operation of slow filtration.
The "Reverse Backwash Fine Sand Filtration Tank" is an advanced water purification system that resolves the shortcomings of conventional slow filtration while inheriting its advantages through fine sand and automatic reverse washing. By using fine sand suitable for the formation of biofilms, it maximizes both physical and biological filtration performance, achieving a balance between filtration capacity and filtration speed. Additionally, as it employs a filtration method that does not use chemicals such as coagulants, maintenance and management are simplified, eliminating the need for advanced technology. 【Features】 ■ Improved purification capacity with fine sand (0.1–0.3mm) ■ Clogging countermeasures with an automatic backwash system ■ Filtration method that does not use chemicals *For more details, please download the PDF or feel free to contact us.
