Abstract
In this study, it is studied to find cryptosporidium distribution, target removal rate using risk management method and to set-up Treatment Technique (TT) guideline suitable in domestic treatment plants. It is also researched the case-study in foreign countries for additional removal level of pathogenic protozoan. It is concluded that it is accredited an additional 0.5 Log removal when an effluent turbidity level in a treatment plant meet 0.15 NTU instead of 0.3 NTU and an additional 0.5Log removal when the treatment plant adapt the sand-filtration and GAC process as filtration process. Meanwhile in the case of membrane filtration it is not exceeded the maximum 4 Log removal accreditation calculating by experimental results.
