other toxic chemicals. The purpose of present work is evaluation of hospitals wastewater treatment

plants performance of Iran University of medical science, analysis and comparison of the

pollutants' removal and sludge quality with the national standards (Iran EPA).

Methods

in this study that was conducted over a period of 6 months, 4 hospitals were selected  out of hospitals of Iran University of medical science. Once in each month were sampled and Totally 72 Samples were obtained (including 6 samples from treatment plant input, treatment  plant effluent and 6 samples from return activated sludge), respectively. 

Results

 The results showed that Shahid Hasheminejad hospital using integrated fixed activated

sludge had the highest efficiency in removal of COD, BOD5 and TSS and Sludge quality meet the B class of EPAstandard.
