Abstract
With the increasing interest of the government of Egypt to the importance of the field of water production and supply, many new drinking water treatment plants (DWTPs) were either constructed or extended during the past few years to provide safe and aesthetic drinking water in sufficient quantities. Performance evaluation of these plants is an essential parameter to be monitored and evaluated for better understanding of operating difficulties in DWTPs. The treatment efficiencies of 5 conventional and 5 direct filtration DWTPs were investigated and compared. Comparative evaluation of certain physical, chemical and biological characteristics of raw and treated water has been used to show the efficiency of the removal of some pollutants. 720 treated and 648 raw water samples were collected with the rate of one treated and one raw water sample from each DWTP monthly during the period from January 2010 to December 2015. Water quality index (WQI) of treated water was calculated. The results indicated that the water treatment plants provide drinking water with acceptable quality coping with Egyptian guidelines and international standards. The exceptions are mainly concerned with the increased turbidity in direct filtration DWTPs and residual aluminum in all DWTPs, with fluctuation in non-conformity of iron and manganese due to some defects in estimation of dosage of the added chemicals, in addition to the deficiency of periodic maintenance rather than design problems. Increasing care of maintenance of water treatment units, control of added dose of alum and chlorine is advised to increase the desired water quality.
