Journal ArticleDOI
TL;DR: The applications of genetic engineering in the modification of the microorganisms for increasing the efficiency of the biofiltration process for heavy metals removal have been critically analyzed and show that the efficiency can be increased three to six folds with the application of recombinant microbial treatment.

TL;DR: In this article, a fiber optical device which provides real-time, on-line, in situ information non-destructively is proposed which can be adjusted to membrane modules, including microbiological and biochemical parameters, and the differentiation between scaling or organic fouling can be performed by FTIR-ATR spectroscopical analysis.

Journal ArticleDOI
TL;DR: Although studies on the application ofdenitrification in freshwater and marine recirculating systems were initiated some thirty years ago, a unifying concept for the design and operation of denitrifying biofilters in recirculate systems is lacking.

TL;DR: In this paper, the authors present the components of organic matter present in WWTP effluents and various treatment methods that may be employed for reduction of EfOM, including flocculation, adsorption, biofiltration, ion exchange, advanced oxidation process, and membrane technology.
Abstract: Wastewater reuse is being increasingly emphasized as a strategy for conservation of limited resources of freshwater and as a mean of safeguarding the aquatic environment due to contaminants present in wastewater. Although secondary and tertiary treated wastewater is often discharged into surface waters, it cannot be reused without further treatment. One of the parameters of concern for human and environmental health is components of organic matter originating from wastewater treatment plant (WWTP) effluents. This effluent organic matter (EfOM) should be carefully characterized in order to find an optimum treatment method for water reuse. This review presents the components of EfOM present in WWTP effluents and various treatment methods that may be employed for reduction of EfOM. These processes include flocculation, adsorption, biofiltration, ion exchange, advanced oxidation process, and membrane technology. The removal efficiency is discussed in terms of removal of total organic carbon, endocrine-disrupt...
