Before introducing the instruments used for chemical wastewater monitoring, let us first clarify the definition and characteristics of chemical wastewater, followed by an overview of online water quality monitoring instruments applicable to chemical wastewater treatment processes.
What is Chemical Wastewater?
Chemical wastewater refers to wastewater generated during chemical production processes, including cooling water, waste gas washing water, process wastewater, and site flushing wastewater. Discharging inadequately treated or untreated wastewater will cause varying degrees and types of water pollution. This pollution will disrupt industrial and agricultural production, damage ecological environments, and pose risks to human health.
Key Characteristics of Chemical Wastewater
- Complex water composition with abundant byproducts. Raw materials mostly consist of solvents or cyclic structural compounds, making such wastewater difficult to treat.
- High concentration of pollutants. This stems from incomplete raw material reactions and residual solvent media introduced into wastewater during production.
- Presence of numerous toxic and harmful substances, such as nitro compounds, halogen compounds, and biocidal surfactants.
- Large quantities of biologically refractory substances, poor biodegradability, and low BOD/COD ratio.
- High colority of wastewater.
Instruments for Chemical Wastewater Monitoring to Ensure Water Safety
Water quality monitors independently developed by Hangzhou-Modi can be selected according to different monitoring parameters. These devices are suitable for chemical wastewater monitoring as well as all other scenarios requiring water quality analysis.
Our main monitoring equipment covers multiple parameters, including online coliform analyzers, online total residual chlorine analyzers, online total nitrogen analyzers, online ammonia nitrogen monitors, online COD analyzers, and online biological toxicity analyzers.
