分析仪
Liquiline System CA80COD enables continuous online chemical oxygen demand (COD) measurement. It monitors the purification capacity of wastewater treatment plants and the billing system for industrial wastewater charged based on discharge volume. Automatic calibration and cleaning save operating costs, and advanced diagnostics with remote access provide process documentation to the relevant authorities. The software-controlled safety functions of the COD analyzer ensure the highest level of workplace safety.
Benefits
COD results obtained by the dichromate method are comparable to laboratory results
Meets industrial requirements: the analyzer is especially suitable for environmental monitoring and industrial and municipal wastewater monitoring
Fast and simple process connection: self-priming version for direct installation or Y-type pretreatment for use in a bypass
Highest safety level: the reactor and all connector parts feature software-controlled safety
Reliable sample transport and high-precision reagent dosing: the peristaltic pump can handle samples containing solids. A light barrier ensures repeatable high-precision reagent dosing
Simple functional upgrade to a complete measuring station: simply add modules and connect Memosens sensors
Application
The Liquiline System COD analyzer monitors:
The inlet and outlet of wastewater treatment plants for documentation and calculation of purification capacity
Industrial wastewater treatment plant discharge volumes to determine discharge fees, forming the basis of the “polluter pays principle”
