14 Industrial Wastewater Treatment Principals and Ideas
14 Industrial Wastewater Treatment Principals and Ideas

For example, the dye factory discharges both acidic wastewater and alkaline wastewater. Due to the difference in fabrics and dyes, the pollutants and pollution effects of textile printing and dyeing wastewater will be very different. Even the wastewater discharged from a set of production unit may contain several pollutants at the same time.
