The plant manufactures touch panel and polarizer which are materials for LCD assemblies. Since the manufacturing process is a semiconductor process, the wastewater contains large quantities of organic solvent from developers, strippers and rinse liquid waste. The wastewater consists of difficult and non-biodegradable chemicals such as Dimethyl Sulphoxide (DMSO, (CH3)2SO), Ethanolamine (MEA, C2H5ONH2) and Tetramethyl Ammonium Hydroxide (TMAH, (CH3)4NOH) that result in the requirement for a large footprint and un-stable operating issues under shock load conditions when using the conventional activated sludge or fixed film process.
