A water purification process that utilizes natural forces and generates little excess sludge.
The water treatment technology "ACA method" fills a special contact material unique to our company, FCR (Food Chain Ring), into an aeration tank to attach bacteria and higher organisms, thereby connecting interactions among microorganisms at a higher level and establishing a food chain. Additionally, by minimizing the extraction of excess sludge and returning settled sludge from the sedimentation tank to the aeration tank, we maintain suspended microorganisms at a high concentration while circulating, promoting self-digestion, minimizing the generation of excess sludge, and purifying wastewater efficiently. **Features** - Minimal generation of excess sludge (zero-emission process) - No bulking occurrence - No need for advanced management technology - Strong against load fluctuations *For more details, please download the PDF or feel free to contact us.*

basic information
[FCR Features] ■ Contains a core with sufficient strength, preventing the detachment of adhering organisms due to aeration. ■ Anaerobic bacteria exist internally, while aerobic bacteria are present externally, mutually suppressing each other, thus preventing the diameter from exceeding 30mm. ■ No backwashing is necessary to maintain a consistent thickness. *For more details, please download the PDF or feel free to contact us.*
