Abstract

A raw wastewater has been treated in wastewater treatment plant of Met Abo El-Kom city using attached growth systems. The treatment was accomplished using an Aerated Fixed Film Reactor (AFFR) with plastic plates or plastic plates with plastic mesh. The first reactor consisted of a number of biofilm carriers from fiber glass plates. Another modified (AFFAR) has been used by modifying the first one by attaching plastic mesh to enhance biofilm area. The system was run in the field for more than six months. Practically, the system consistsed of four stages as with bafflers at hydraulic loading rate (HLR) of 0.1 and 0.2 m3/m2/d.
The results showed under HLR= 0.1 m3/m2/d for the first reactor has achieved a removal efficiency of 89%, 95%, 90% and 93% for COD, BOD5, NH3 and TSS respectively. However, the second modified reactor achieved high removal efficiency more than the first one because of the large biofilm area. The second reactor has achieved a removal efficiency of 94%, 98%, 95% and 97 for COD, BOD5, NH3 and TSS respectively.
The influent BOD5 has been decreased from of 600 to 7 mg/l with removal percentage 98%. Removal of COD and SS was almost similar to that of BOD.
The initial COD and SS of 800 mg/l and 510 mg/l come down to 71 mg/l and 20 mg/l respectively. In addition, the present study illustrated that use of biofilm carrier (plastic plates) improve the growth of biomass above surface area of plates and have a relative large surface area in small volume. Results also indicated that better removal efficiency can be obtained in case of low hydraulic loading rate of 0.1m3/m2/d especially for BOD5 and COD. While in case of modified AFFR the effluent improved BOD5, COD, NH3 and TSS removal.
