Presentation Title
Strategic Water and Resource Recovery with Macro Porous Polymer Extraction (MPPE) Towards Circular Economy
Presentation Abstract
Wastewater streams of wafer fabrication, micro-electronics packaging and testing processes pose a challenge to facility managers. Such processes are typically flushed with a cocktail mixture of various chemicals such as silicon, etching agents, hydro-fluoric acid, waste copper, sulfate solution, and solvents.
With the right technologies, semiconductor manufacturers could improve water recycling rate in addition to the recovery of valuable materials. A semiconductor components manufacturer in Taiwan is setting the direction for new and modernized wastewater treatment plants around the world, implementing the ideas of sustainable development and the circular economy.
The paper will summarize our experience gained during years of solvent recovery, water reclaim and reuse for various industries, one of which is a semiconductor components manufacturer in Taiwan:
1. Reclaim and reuse of water.
2. Removal and recovery of organic solvents (isopropyl alcohol).
3. Recovery of hydrocarbons.
The conventional wastewater treatment plant in Taiwan was transformed into a water recycling plant - where multiple streams of organic wastes are reclaimed and reused.
