Sewage discharge monitoring, sewage monitoring system KNF-400C is based on urban waste treatment station, sewage discharge, enterprise discharge and other water quality monitoring related requirements and research and development, strengthen the safety management of urban discharge to provide basis and support and research and development of water quality online monitoring system, Mainly for COD, ammonia nitrogen, PH, dissolved oxygen, turbidity, temperature and other water quality to implement online and early warning, the product adopts modular design, easy installation and maintenance, suitable for single point and large area distribution monitoring needs.
Overview of KNF-400C on-line monitoring system for wastewater quality：
KNF-400C is an on-line water quality monitoring system based on the relevant requirements of water quality monitoring such as urban garbage disposal station, sewage discharge and enterprise discharge, which provides the basis and support for strengthening the safety management of urban discharge. It mainly carries out on-line and early warning for the temperature, conductivity, turbidity, COD, ammonia nitrogen, PH and dissolved oxygen of water quality. The product adopts modular design, is easy to install and maintain, and is suitable for the monitoring needs of single point and large area distribution.
At the same time, based on the research and development, production and operation experience in water quality online terminal monitoring equipment, data acquisition and transmission, environmental monitoring and management system, Shenzhen Kenafu has a long-term, stable and effective solution for the monitoring characteristics of drinking water. The system can realize the digital management of the whole process of monitoring and analysis of drinking water, data acquisition and transmission, equipment anti-control, monitoring and early warning, etc., which promotes the informationization and modernization of water environment management and can comprehensively improve the management level.
