J-COS, Smart Jar-test techniques Coagulant-dosing Optimization System
Jar-test Smart techniques Coagulant-dosing Optimization System
As a product that was selected and developed as a national research & development project through the MOU on joint development with Seonam/Jungnang Sewage Treatment Center in Seoul,
J-COS is a system that promptly analyzes water quality property in the rear end of bioreactor in sewerage/wastewater treatment facility and that of total phosphorus (T-P) processing facilities, and optimally controls coagulant-dosing in real time.

Product Features
Pretreatment system using non-pressure gravity filtering method
- Prevents water quality measurement error caused by impurities, and failure of measuring equipment
- Automatic built-in water & chemical cleansing function
Accurately measures phosphorus concentration (P)
SMART Jar-test device (applying 5 min cycle PO4-P measurement equipment)
- Derives changes in efficiency of coagulant according to sewage flow property (phosphorus concentration, COD, alkalinity, etc.) through automatic jar-test
Promptly measures changes in water quality and properties, and optimally controls coagulant dosing
Overlap Process
- Promptly measures water quality and composes process to enable jar-test
Orders a 5-min unit optimal dosing
Feedback Control System
- Analyzes phosphorus concentration of process water before discharge -> Verifies coagulant dosing
Proactive response against emergencies
Complying with Legal Discharge Water Quality
Reduction of Coagulant Dosing by 20%
Increasing Operation Convenience
