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.

The major pollutants found in offset printing waste are mainly characterized as volatile organic carbon (VOC), which is extremely toxic to the environment and difficult to be treated by the conventional process [2]. Investigation on chemical characteristics of printing ink wastewater revealed that the BOD 5
