A water purification process that utilizes natural forces and generates minimal excess sludge.
The water treatment technology "ACA method" fills our unique special contact material [FCR: Food Chain Ring] into the aeration tank, allowing bacteria and higher organisms to attach, 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 efficiently purifying wastewater. [Features] ■ Minimal generation of excess sludge (zero emission process) ■ No occurrence of bulking ■ 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 attached organisms due to aeration. ■ Anaerobic bacteria exist internally, while aerobic bacteria are present externally, mutually inhibiting each other, so the diameter does not exceed 30mm. ■ No need for backwashing to maintain a consistent thickness. *For more details, please download the PDF or feel free to contact us.
