摘要: In this study, the dewaterability characteristics of electroplating sludge have been investigated after treatment with microwave irradiation. While specific resistance to filtration (SRF) was used evaluate dewaterability, water content (WC) in and soluble chemical oxygen demand (SCOD) were determined describe observed changes dewaterability. SRF decreased from 3.54E + 09 m/kg 4.33E + 08 m/kg, WC 98.56 wt.% 94.37 at 800 W 120 s. Sludge solubilization increased power, but deteriorated higher contact times due adverse effects sustained A full factorial design along response surface analysis applied determine an optimum combination power time for effective enhancement. Based on statistical observations numerical optimization using desirability function analysis, 141 s optimal conditioning requirement which yielded minimum WC, while also ensuring maximum disintegration.
