The dosage is determined by pH control approach, which does not require a routine jar test. This method can simultaneously determine the optimal pH and economical dosage for oxide-CMP wastewater. The coagulant can be added directly into the raw water without the pH adjusting at first. According to this method, the coagulant acts like a titrant and the pH of the oxide-CMP wastewater is monitored. The optimal dosage is the one that corresponds to a specific pH.
本论文主要以「pH控制法」来决定线上加药剂量值,其与传统瓶杯试验不同的是,其加药逻辑可直接对线上加药进行控制且毋须定期确认参数。pH控制法视混凝剂为酸滴定药剂,直接对进流之氧化层研磨废水进行加药,及至特定pH时,加药停止,此时之加药量即为电性中和去稳之控制点,远较过量加药法经济。
