Biochemical parameters such as soluble chemical oxygen demand (SCOD), phosphate, ammonium nitrogen and proteins are often used to characterize the efficiency of disintegration of waste activated sludge (WAS) flocs and microorganism cells. In this study, the chemical disintegration using peroxymonosulfate (MPS, Oxone) and thermally activated MPS, were evaluated for the destruction of WAS. Our study was conducted for chemical disintegration of WAS by MPS in doses between 84.7 - 847.5 mg/g(TS) activated by temperatures of 50, 70 and 90 °C over 30 minutes. The application of these methods causes an increase in the soluble COD value and protein concentration in the supernatant. Also, they positively influence the sludge volume index (SVI) which decreased from 89.8 to 17.2 ml/g. Our research work confirmed that the application of thermally activated MPS may become a new effective way of improving sewage treatment and sewage sludge processing.
