  • What is the current treatment process for semiconductor wastewater?
  • The current treatment process includes dewatering and sludge thickening. These methods are insufficient to achieve the concept of zero discharge. Semiconductor wastewater contains high ammonium ions from the utilisation of raw substances during the manufacturing process.
  • Why is semiconductor wastewater treatment important?
  • The increasing amount of semiconductor wastewater generated and discharged and the use of various chemicals in the semiconductor fabrication process highlight the necessity and importance of semiconductor wastewater treatment. This review describes various physical, chemical, biological, and hybrid or combined processes.
  • What is microelectronics industry wastewater?
  • The microelectronics industry wastewater is attracting the scientific community and industry attention due to the high amount of organic and inorganic pollutants produced. Pollutants in microelectronic wastewater are considered qualitative contaminants, found in low concentrations but present with high risks to the environment and public health.
  • How much does the semiconductor industry spend on water and wastewater treatment?
  • The semiconductor industry spends more than US dollar one billion on water and wastewater treatment systems annually. A typical factory semiconductor production consumes about 40% of UPW, mostly used for washing and cleansing (Drouiche et al. 2007).
