| Abstract | ||||
| THE PRESENT study deals with real greywater. The …..objective of this study is to investigate the treatment of greywater for the purposes of reuse. Greywater treatment was examined first to determine the optimum degreasing / settling time. Further treatment by hybrid constructed wetland was examined. Efficient removal of the pollutant parameters was achieved. The experimental method involves evaluation of the treated effluent to reach the allowable limits of water reuse according to “Egyptian Environmental Association Affair, EEAA”. Final removal rates reached 87%, 83%, 88%, 91%, 36%, 92%, and 58% for the TSS, COD, BOD5, TP, NO3, oil & grease and TKN, successively. The E. coli count and the number of cells or eggs of Nematode in the final effluent reached 100/ml and “1 egg/L”, respectively. | ||||
