Synopsis

Semiconductor is a fuel to boost digital economy. Demand for chips increase as the application of Artificial Intelligence puts more pressure on the semiconductor supply chain. This needs to achieve through sustainable manufacturing to minimize negative impacts to the environment. In manufacturing, there are many ways to become more sustainable while achieving the bottom line. In this talk, ways to achieve sustainability in manufacturing, challenges as well as learning from other industries will be discussed.

Synopsis

In this study, a treatment plant for semiconductor and electronics wastewater was investigated. The treatment includes (i) Fenton-related advanced oxidation process (AOP) accompanied by coagulation, and (ii) microfiltration (MF) and reverse osmosis (RO). The pre-treatment processes were operated based on optimal conditions which were experimentally determined. For RO membrane system, the plate frame RO (PFRO) and spiral wound RO (SPRO) were used to obtain high-quality permeate, while the high pressure (HP PFRO) module was employed for recovering of concentrated streams.

Results showed that during 5 months on-site operation, significant COD removal efficiency of 26.23%, 19.64%, and 99.62% were found at Fenton, coagulation, and SPRO units, respectively. The heavy metal concentration (i.e., Cu, Fe, Zn, Mn, Cr) measured in the effluent also satisfied the allowable discharge levels. In addition, high recovery rate of permeate can be obtained from different RO modules (i.e., PFRO 56%, HP PFRO 9.11%, especially SPRO > 80-90%).
