Recent developments in photocatalytic degradation of pesticides and phenols in storm and wastewater effluent by Saber Ahmed( )

1 edition published in 2011 in English and held by 2 WorldCat member libraries worldwide

The heterogeneous photocatalytic oxidation process offers a versatile promise in the detoxification and disinfection of wastewater containing hazardous organic compounds such as pesticides and phenolic compounds in storm and wastewater effluent. This process has gained wide attention due to its effectiveness in degrading and mineralizing the organic compounds into harmless and often useful components. To develop an efficient photocatalytic process, titanium dioxide has been actively studied in recent years due to its excellent performance as a photocatalyst under UV light irradiation. This paper aims at critically evaluating and highlighting the recent developments of the heterogeneous photocatalytic systems with a special focus on storm and wastewater treatment applications

Sustainable reuse of storm/waste-water resources : a review on solar photocatalytic purification processes by Saber Ahmed( )

1 edition published in 2009 in English and held by 1 WorldCat member library worldwide

In recent years, there has been a significant amount of research and development in the area of solar photocatalysis. This paper reviews and summarizes the mechanism of photocatalytic oxidation process, types of photocatalyst, and the factors influencing the photoreactor efficiency and the most recent findings related to solar detoxification and disinfection of water contaminants. Various solar reactors for photocatlytic water purification are also briefly described. The future potential of solar photocatlysis for storm water treatment and reuse is also discussed to ensure sustainable use of solar energy and storm water resources
A review on the role of operating parameters in heterogeneous photo catalytic water purification processes for storm and wastewater reuse by Saber Ahmed( )

1 edition published in 2010 in English and held by 1 WorldCat member library worldwide

In recent years, there has been an enormous amount of research and development in the area of heterogeneous photocatalytic water purification processes due to their effectiveness in degrading and mineralizing recalcitrant organic compounds. This paper reviews and summarizes twenty seven recently published works on the photocatalytic oxidation of toxic organic compounds e.g pesticides and herbicides, predominant in storm and waste water effluent. In this review, the effects of various operating parameters on the photocatalytic degradation of pesticides and herbicides are discussed. Recommendations are made for future work to eliminate the drawbacks pertaining to this treatment process
Computational fluid dynamics analysis of a flat plate photocatalytic reactor for storm and wastewater reuse by Saber Ahmed( )

1 edition published in 2010 in English and held by 1 WorldCat member library worldwide

A computational fluid dynamics (CFD) analysis has beenperformed for a flat plate photocatalytic reactor using CFD codeFLUENT. Under the simulated conditions(Reynolds number, Rearound 2650), a detailed time accurate computation shows thedifferent stages of flow evolution and the effects of finite lengthof the reactor in creating flow instability, which is important toimprove the performance of the reactor for storm and wastewaterreuse. The efficiency of a photocatalytic reactor for pollutantdecontamination depends on reactor hydrodynamics andconfigurations. This study aims to investigate the role of differentparameters on the optimization of the reactor design for itsimproved performance. In this regard, more modelling andexperimental efforts are ongoing to better understand theinterplay of the parameters that influence the performance of theflat plate photocatalytic reactor
