Abstract
- The study explored the treatment of different wastewater by producing microelectronic components. It proposed using aerobic biological treatment for the first effluent containing tetramethyl ammonium hydroxide and chemical-physical processes for the other two streams having fluorides, phosphates, nitrates and acetic acid. The novel integrated process significantly reduced environmental impacts by an average of 50 % compared to current disposal methods. The economic analysis indicates a 30 % reduction in treatment costs for the first effluent and lesser reductions for the other two effluents. The study revealed that treating all three effluents in an integrated manner is cost-effective, reducing investment and operating costs.
