Improvement of water treatment plants capacity and effluent quality by introducing "NINIVITE" as new filtration media

  This work compares the performance of four types of filters, three of them are dual media/capping filters and the fourth is a single medium sand filter. The filters were made to operate with the same effective size and the same depth. These filter were subjected to the same operating conditions of filtration rates and influent turbidity. A new locally available filter medium called ninivite (recently...

Scouring control of the eroded stilling basin: Case study, Namrood Dam

  Local scouring immediately downstream of stilling basin is unavoidable local velocity exceeds incipient motion velocity. This phenomenon causes a difference level between concrete floor of basin and river bed. In such circumstances a riprap is normally used to prevent the development of scouring hole. In this study, hydraulic model of Namrood dam is used to estimate stone size that is able to resist scouring...
