How to reduce harmful substances in water treatment chemicals manufacturers?

Reducing harmful substances in water treatment chemicals manufacturers requires starting from three aspects: source control, process optimization, and end of pipe treatment:
source control
Optimize production processes, use more environmentally friendly raw materials to replace traditional harmful substances, or adjust formulas to reduce the proportion of harmful ingredients. For example, in the production of chemical raw materials, wastewater can be treated by the iron carbon+Fenton method, which can remove organic matter and heavy metal ions, simplify the process flow, and reduce costs. ‌
Process optimization
Physical method: using sedimentation tanks, air flotation devices, etc. to remove large particulate matter and oily pollutants, reducing the subsequent treatment load
Chemical method: Treating wastewater through coagulation sedimentation, neutralization reaction, etc., such as using coagulants to coagulate small particles and remove them
Biological method: Aerobic/anaerobic reactors decompose organic matter, and activated sludge process reduces pollutant concentration through microbial metabolism
end treatment
Install intelligent monitoring devices to monitor water quality in real time, and issue warnings if it exceeds the standard; Establish emergency plans to deal with sudden leaks and ensure that wastewater is discharged in compliance with standards. For example, North Carolina uses granular activated carbon to adsorb perfluorinated compounds (PFAS), and then decomposes harmful substances through high-temperature incineration to achieve circular regeneration.
