Aerobic Treatment

چکیده
Aerobic treatment has many advantages including: 1) minimum odor when properly loaded and maintained; 2) large biochemical oxygen demand (BOD) removals providing a good quality effluent; 3) high rate treatment allowing smaller scale systems, e.g., less land required; 4) the final discharge may contain dissolved oxygen which reduces the immediate oxygen demand on a receiving water; and 5) the aerobic environment eliminates many pathogens present in agricultural wastes.

Poultry Slaughterhouse Wastewater Treatment Using Anaerobic Fluid Bed Reactor and Aerobic Mobile-Bed Biological Reactor
This research evaluated the efficiency of combined anaerobic-aerobic processes for the treatment of slaughterhouse wastewater. The anaerobic reactor consists of a 3.95 L Plexiglas column with 60 mm diameter and 140 cm height. The cylindrical particles of polyvinyl chloride with 2 mm diameter and 1250 kg m-3 density packed to 60 cm of column were used as biomass saving material. The d...
متن کاملon anaerobic – aerobic treatment of industrial and municipal wastewater
Anaerobic–aerobic systems have been remarkably employed in industrial and municipal wastewater treatment for many years. While previously most treatment of wastewaters have been carried out in conventional anaerobic–aerobic treatment plants, in recent years, high rate anaerobic–aerobic bioreactors have been increasingly employed for wastewaters with high chemical oxygen demand (COD). This paper...
متن کاملEvaluation of COD and BOD5 Removal Efficiency by Combined Treatment Aerobic-Anaerobic (AO) on Sewage of Metal Industries
Shortage of water resources and renewable per capita in last 30 years is put Iran on crisis threshold. Wastewater reuse is one of the battle solutions for water shortage and prevents wastewater depletion and environmental pollution. Thus, a pilot scale experiment was carried out to evaluate an integrated anaerobic/aerobic treatment for removal of BOD5 and COD, also to reduction of hydraulic ret...
متن کاملComparing the Effects of 4 and 12 Weeks of Aerobic Training on Tumor Volume in Female Mice with Breast Cancer
Introduction: Tumor size is a contributing factor in cancer prognosis. On the other hand, regular exercise may play an important role in inhibiting tumor growth in breast cancer. Because of the key role of tumor volume in tumor metastasis, the aim of the present study was to compare the effects of a 4-week and a 12-week aerobic training on tumor volume in female mice with breast cancer. Methods...
متن کاملFundamental and application of aerobic granulation technology for wastewater treatment
Biogranulation has been studied widely and successfully industrialized for the last two decades. Biogranulation technology for wastewater treatment includes anaerobic and aerobic granulation processes. Even though anaerobic granulation has been relatively well studied and known, studies on aerobic granulation have begun recently. The aerobic granular sludge is known to have denser and stronger ...
