Abstract
Achieving high efficiencies in anaerobic baffled reactor (ABR) for reducing chemical oxygen demand (COD) has always been an outstanding challenge for most researchers as most experiments focus on using fibers in ABR to reduce COD. In this paper a new material was introduced as a replacement for fibers which is the agricultural waste such as palm fibers and ficus trees. The Effect of using agricultural wastes on the performance of the (ABR) in reducing COD was tested for four different stages (start-up, steady state, shock and final). Both palm fibersand ficus trees samples achieved higher COD removal efficacies as compared to previous studies. The palm fiber samples achieved the highest COD removal efficiency in the four stages as compared to the ficus tree samples.The COD removal efficiency of palm fiber sample reached an average value of 93.07% and a pH value ranging between 6.99 to 7.15 where the ficus tree samples reached 88.37%and a pH value ranging between 6.9 to 7.12. The reason why palm fiber samples reached high efficiencies could be contributed to the nature and characteristics of the palms. Palms have high surface area and void ratio which allow the acidogenic bacteria to breed and replicate, which decompose the organic materials.

Comments
In this paper we have reviewed different techniques for the anaerobic wastewater treatment with Using Agriculture Wastes ABR(C) system gave the highest COD% removal comparing with the other systems due to large void ratio in palm fiber media, also may be surface type for this media Creates a suitable surface for the breeding of bacteria. Palm fiber improve the removal efficiency by 28 %, while the ficus trees improves the removal efficiency of the anaerobic reactor by 22 %. pH value decreased with time which decreases the COD % removal. Must keep the characteristics of attached media (palm fiber) ABR (c) make a contact with the bacteria, void ratio and higher surface area for an order to be the highest COD % removal. Results showed that decreasing pH value had an adverse effect on treatment efficiency for all cases.
