Evaluation and Optimization of COD Removal Performance for a Domestic Wastewater Treatment Plant by Response Surface Methodology: The Case of Van Muradiye

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In this study, the performance of the Van Muradiye Domestic Wastewater Treatment Plant was evaluated with Response Surface Methodology (RSM). The effects of pH, conductivity, dissolved oxygen (DO), and suspended solids (SS) on the chemical oxygen demand (COD) removal efficiency were evaluated using samples collected from the plant's inlet and ...

Generation and properties of aerobic granular sludge

Water Science and Technology, 2001
A sequencing batch reactor (SBR) was used to investigate the generation of different granules cultured under aerobic and alternating anaerobic/aerobic conditions. The reactor was fed with synthetic wastewater. A substrate loading rate of 3.6 kg COD/ (m3 day) was applied. Granules of heterotrophic microorganisms were formed. After the first experimental

Effects of microplastics on granular sludge: A review [PDF]

E3S Web of Conferences
Biogranules are recently regarded as promising methods with intensive density and satisfying settleability for waste treatment and resource recovery. Wastewater treatment plants (WWTP) were regarded as “sinks” for Microplastics (MPs) and amount of MPs ...

Dark Heritage Prospection ‐ Mapping the Treblinka II Extermination Camp Using a Magnetometer Survey and Integrated Archival Sources

Archaeological Prospection, EarlyView.
ABSTRACT The history of Nazi German extermination camps has, until recently, relied primarily on eyewitness testimony. Very few official documents detailing the facilities survived the war due to the special operation ‘Sonderaktion 1005’, dedicated to hiding their existence and extent.

Anaerobic Biological Treatment of High Concentration Wastewater

Chemical Engineering Transactions, 2018
Granular sludge is the key to the efficient operation of the UASB reactor, which directly affects the treatment efficiency of the reactor. The ordinary flocculent sludge is lighter, and it is easy to be flushed out of the reactor under the action of the ...
