The microalgae Chlorella vulgaris ATCC 13482 was used in the present study for municipal wastewater treatment. Batch experiments were performed in bubble column photobioreactors of 7 L working volume maintained at 25 ± 2°C and 14 h/10 h of photo and dark cycle. The treatment process was enhanced by using CO2-augmented air (5% CO2 v/v) supply into t...

Fibrous filters, which are the most commonly used means of particle filtration, are generally characterized by the air pressure drop and filtration efficiency. The nature of particle movement and interaction between the particle and fibre is of great importance for measuring the filtration efficiency of fibrous filters. Majority of previous studies...

In the present study, a biosensor was developed for the detection of organophosphorous compounds. Core electrode of a working electrode was obtained by depositing the paste of Gold nanoparticles and Multi-walled Carbon Nanotubes on a gold wire. The acetylcholinesterase enzyme was immobilized on carboxylated Single-walled Carbon Nanotubes and pasted...

The feasibility of coupling photocatalysis and a biological treatment to remove a herbicide - 2,4-dichlorophenoxy acetic acid (2,4-D) - from pure water was examined using batch experiments following three protocols: aerated (A-BR) and non-aerated biodegradation (NA-BR) alone, and intimately combined photodegradation and biodegradation (P-B). In vie...

A novel wastewater treatment process, known as an alternating activated sludge reactor (AASR), is proposed to treat wastewater in full-scale operations. The AASR is a technical development based on the sequencing batch reactor (SBR) and cyclic activated sludge technology (CAST). The performance of AASR was evaluated in this study and found to be ef...

One of the bottlenecks often encountered in electro-Fenton technology is its low ability to produce hydrogen peroxide (H2O2). Thus, the hunt of suitable electrodes and reactor are a must to be tackled in order to improve the efficiency of the system. In this study, three-dimensional nickel foam was selected as cathode for in situ generating H2O2 ef...

This study was undergone to investigate the adsorption characteristics of tetrachloroethylene (PCE) on water supply network growth ring. According to the chemical composition of real network growth ring, iron oxide mixture containing synthesized goethite and lepidocrocite was applied as simulated growth ring. The results demonstrate that competitio...

The photodegradation of methyl orange in water by the catalyst TiO2 or the oxidants (H2O2, KIO4) or their combination (TiO2 + H2O2, TiO2 + KIO4) under UV light illumination is studied. During the above process, as far as the photodiscoloration degree of methyl orange is concerned, the effect sequence is KIO4 + TiO2 >> KIO4 > TiO2 + H2O2 > TiO2 > H2...

Growth studies are important to increase the knowledge about the physiology of microalgae. The development of suitable culture media allows optimum growth to each species. The genus Chlorella has the ability to adapt to various environmental and nutritional conditions. Thus, the aim of this work was to evaluate the physiology of Chlorella sorokinia...

Bactericidal proteins from the Moringa oleifera seed are reported to be suitable alternatives to conventional methods of bacterial reduction in water. In this study the cationic bactericidal M. oleifera proteins were isolated by attachment onto the surface of silicon dioxide. This functionalised SiO2(ƒ-SiO2) was then exposed to Escherichia coli and...
