Dairy industry wastewater is rich in organic content, presenting a high biodegradability, and therefore biological treatments are widely employed. This study aimed to evaluate biosolids production three systems: activated sludge (AS), movingbed biofilm reactor (MBBR), sequencingbatch (SBMBBR). Simulated dairy was used at different load rates (OLRs): 1.22, 2.87, 5.44 gCOD L−1d−1. Besides product...

Abstract: The selection of a suitable type of reactor for the reaction with enzymes immobilized on the carriers is extremely important to industry. In this study the possibility of using pre-selected cellulose-based carriers (Granocel) to conduct the reaction in a stirred batch reactor and a fixed-bed reactor was investigated. It was shown that non-activated Granocel did not undergo compression...

Lignocellulosic biomass is a renewable resource used to produce energy, fuels, and chemicals. This study aimed determine the effect of pyrolysis temperature on product yield characterization bio-oil. In this study, palm shells were selected prepared as raw materials for bio-oil production. Palm first soaked in 10% HCl then pyrolyzed at temperatures 300 oC, 350 400 450 oC fixed bed reactor. Afte...

background detergents and difficulties of their presence in the water and wastewater cause various problems such as foam production, anomalies in the growth of algae, and accumulation and dispersion in aqueous environments. objectives the aim of this study was to examine and compare the moving bed biofilm reactor with another reactor without media (carries) for anionic surfactants removal. mate...

ANITATM Mox is a new one-stage deammonification Moving-Bed Biofilm Reactor (MBBR) developed for partial nitrification to nitrite and autotrophic Nremoval from N-rich effluents. This deammonification process offers many advantages such as substancial reduction in aeration requirement and sludge production along with the lack of need for an external carbon source. In this paper, we present the ex...

Intermittent aeration process can be easily applied on the existing activated sludge system and is highly reliable against the loading changes. It can be operated in a relatively simple way as well. Since the moving-bed biofilm reactor method processes pollutants by attaching and securing the microorganisms on the media, the process efficiency can be higher compared to the suspended growth biol...
