KLa Slot Injector Aeration System For CFAS Process Touch Panel Manufacturing Plant Wastewater Treatment
By KLa Systems
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.
