Microbial Kinetic Analysis of a Hybrid UASB Reactor

by

Yalcin Askin Oktem et al. View all

Microbial kinetics of a hybrid upflow anaerobic sludge blanket (UASB) reactor were investigated when treating chemical synthesis–based pharmaceutical wastewater. Monod, Grau first-order, Grau second-order, Stover-Kincannon, Chen & Hashimoto kinetic models were applied to the hybrid reactor. The...

Optimization of photocatalytic degradation of naproxen from aqueous solutions with UV/ZnO process: Response Surface Methodology (RSM)

by

Mohammad Malakootian et al. View all

Water and Wastewater Treatment

The aim of this study was to optimize the removal of Naproxen (NPX) by the UV/ZnO photocatalytic process using response surface methodology based on Central Composite Design (CCD). The effect of parameters such as ZnO concentration, contact time, pH, temperature, and initial NPX concentration were...

Urban land use effect analysis on the level of noise pollution using satellite and GIS technologies: A case study in Tehran city

by

Babak Djahed et al. View all

General

We utilized satellite and GIS technologies to address the relationship between urban land uses and Noise Pollution (NP) in one of the most crowded regions of Tehran city. Leq was determined in 170 stations of the studied area and an acoustic map was created. Moreover, using satellite remote sensing...

Rapid start-up of anammox reactor using granular sludge supported on activated carbon

by

Wenjie Zhang et al. View all

Water and Wastewater Treatment

The long start-up time and high demand of anaerobic ammonium oxidation (anammox) limit the practical applications of the anammox process. In this study, granular sludge supported on activated carbon (AC) was used as seed sludge. The start-up time of the reactor was substantially shortened, and the...

Functionalization of Amberlite XAD-4 with 8-hydroxyquinoline chelator using aryldiazonium radical reaction and its application for solid phase extraction of trace metals from groundwater samples

by

Awadh O AlSuhaimi et al. View all

Water Quality

In this work, the aryldiazonium salts radical addition method has been used successfully to anchor 8-hydroxyquinoline (8-HQ) moieties onto the surface of Amberlite XAD-4 beads. The nitroaniline aryldiazonium salt was generated (in-situ) and covalently grafted onto Amberlite XAD-4 by aid of...

Application of the Analytic Hierarchy Process (AHP) to select the best oil spill cleanup method in marine protected areas for calm sea condition

by

Giambattista Guidi et al. View all

Oil spill cleanup is a complex and expensive activity. There are several commonly used techniques available today. The paper suggests criteria for the selection of the best available technique that could be employed in case of oil spills in the Mediterranean Sea under specific circumstances, i.e...
