Using these  models, the performance of a given unit operation can be predicted.  In the present study, the following models were used to predict the  performance of flocculation, sedimentation and filtration, respectively.  Boadway's Flocculation Model  Camp's Sedimentation Model  O'Melia-Ali's Filtration Model  Suitable ranges of values of the parameters used in individual models  are used in integral water treatment model to select the most techno-econo-  mic solution.10aWater quality managementxNepalxPhewa Lake1 aVigneswaran, S.,eChairperson1 aHuynh, Ngoc Phien,eExamination Committee1 aLohani, B.N.,eExamination Committee2 aThe Federal Republic of Germany,eScholarship Donor2 aAsian Institute of Technology.tThesis ;vno.
