Printing and dyeing wastewater refers to the residual dyeing liquid, rinsing water and pretreatment (such as scouring, degumming, desizing, etc.) during the dyeing or printing and dyeing process, as well as the mixed wastewater from the finishing process, which contains a certain amount of harmful substances and colored wastewater. In 2019, this printing and dyeing factory in Suzhou used Yosemitech's Y4000 multi-parameter sonde(temperature, DO, pH, turbidity, conductivity) and UV254 COD sensor in the wastewater pool. In addition, it was equipped with Yosemitech's pipe network water quality monitoring system, which is solar-powered and can achieve real-time automatic monitoring of 6 water quality indicators in the wastewater pool of the printing and dyeing factory, enabling timely grasp of the water quality status in the wastewater pool, understanding the water quality change patterns, and providing decision-making support for wastewater treatment work.

Features of Yosemitech Y4000 Online Multi-parameter Sonde:

-Digital sensor, RS485 output, supports MODBUS;

-All calibration parameters are stored in the sensor. Each probe is equipped with a waterproof connector, which can be conveniently plugged and unplugged for replacement.

-Equipped with an automatic cleaning device, it can effectively remove contaminants from the sensor surface, prevent microbial growth, and ensure greater accuracy with lower maintenance.

-Optional sensors include fluorescence dissolved oxygen, four-electrode conductivity, fiber optic turbidity, digital pH, digital ORP, chlorophyll, blue-green algae and oil in water. They are suitable for long-term online monitoring.

-The multi-in-one structure design enables simultaneous connection of six probes to measure seven parameters.

Features of Yosemitech UV254 COD Sensor:

-Digital sensor, RS-485 output, supports MODBUS;

-No reagents are needed, no pollution, and it is more economical and environmentally friendly.

-It can measure parameters such as COD, TOC, turbidity and temperature.

-It automatically compensates for turbidity interference and has excellent testing performance.

-Equipped with a self-cleaning brush, it can prevent biofouling and has a longer maintenance cycle.
