Intermittent Aeration in Biological Treatment of Wastewater
Problem statement: E-coating process is widely used to provide a protective coating layer on metal parts in the automotive and metal finishing industry. The wastewater from the coating process contains organic compounds that are used in the cleaning, pretreatment and coating steps. Organic pollutants can be removed biologically. In the aerobic biological treatment, water aeration accounts for a...
متن کاملEffects of nanobubble aeration in oxygen transfer efficiency and sludge production in wastewater biological treatment
Low efficiency of conventional aeration techniques and the excessive production and disposal of sludge are great concerns in biological wastewater treatment systems. The present study aimed to evaluate the active sludge method using batch reactors under continuous operation to determine the efficiency of aeration and sludge production through microbubble and nanobubble aeration. The results ind...
متن کاملWastewater Treatment in Moving-Bed Biofilm Reactor operated by Flow Reversal Intermittent Aeration System
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...
متن کاملNitrogen Removal and N20 Emission in a Full-Scale Domestic Wastewater Treatment Plant with Intermittent Aeration
Nitrous oxide (NzO) is emitted from wastewater treatment processes. It is known as a greenhouse gas that contributes to global warming (over 200 times more per molecule than carbon dioxide) and to the destruction of the ozone layer. It is therefore of great importance to develop technology that can suppress N20 emission. The effects of an anoxic period on NzO emission and nitrogen removal were ...
متن کاملThe treatment of pig slurry by a full-scale Anaerobic-Adding Raw Wastewater-Intermittent Aeration Process
article as: Deng L, et a ation Process, Biosystem The performance of an Anaerobic-Adding Raw Wastewater-Intermittent Aeration (ANARWIA) process was investigated in a full-scale plant. After 1 year’s operation, a successful treatment for swine wastewater had been developed, without adding alkali or external organic matter. The anaerobic unit can maintain chemical oxygen demand (COD) removal effi...
