TL;DR: In this article, the performance limitations, future prospects, and improvements of the common used dyes decolorization and decoloring with external voltage or current supply in Bioelectrochemical systems are reviewed.
Abstract: Bioelectrochemical systems or electrochemical reduction reactors have great potential for treating wastewater that contains dyes for decolorization. They are reported to enhance decolorization rate and degree with external energy supply and to help microorganisms or noble metal as catalysts. Till now literatures regarding dye decolorization with electron reduction using BESs or electrochemical reactors is deficient. This paper reviews the performance limitations, future prospects, and improvements of the common used dyes decolorization and decolorization with external voltage or current supply in Bioelectrochemical systems.

TL;DR: In this paper, a treatment device capable of intensifying degrading of wastewater containing azo dyes by a microbial electric auxiliary system and a water treatment method, belongs to the field of printing and dyeing wastewater treatment and mainly relates to wastewater treatment device and method.
Abstract: The invention relates to a treatment device capable of intensifying degrading of wastewater containing azo dyes by a microbial electric auxiliary system and a water treatment method, belongs to the field of printing and dyeing wastewater treatment and mainly relates to wastewater treatment device and method. The invention aims to solve the technical problem that existing method of treating wastewater containing azo dyes is low in decolourization ratio of wastewater and poor in COD removing capacity. The device provided by the invention comprises a reactor anode collector plate, a reactor cathode collector plate, a reference electrode, a reactor water inlet, a mud discharge opening, a reactor perforated water distributing plate, a return pipe, a return pump, a lead, a water outlet, an anode filler layer clapboard, a cathode filler layer clapboard and a gas collecting opening. The water treatment method comprises the following steps that wastewater enters the treatment device capable of intensifying degrading of wastewater containing azo dyes by the microbial electric auxiliary system through the reactor water inlet; water is discharged from the water outlet to realize water treatment. The method provided by the invention is high in decolourization ratio of wastewater and high in COD removing capacity when used for treating wastewater containing azo dyes.

TL;DR: In this paper, a review of the literature on microalgae that were cultivated using captured CO_2, technologies related to the production of bio-fuels from micro-algae and the possible commercialization of micro-algal-based bio-fuel.
Abstract: Fossil fuels, which are recognized as unsustainable sources of energy, are continuously consumed and decreased with increasing fuel demands. Microalgae have great potential as renewable fuel sources because they possess rapid growth rate and the ability to store high-quality lipids and carbohydrates inside their cells for biofuel production. Microalgae can be cultivated on opened or closed systems and require nutrients and CO_2 that may be supplied from wastewater and fossil fuel combustion. In addition, CO_2 capture via photosynthesis to directly fix carbon into microalgae has also attracted the attention of researchers. The conversion of CO_2 into chemical and fuel (energy) products without pollution via this approach is a promising way to not only reduce CO_2 emissions but also generate more economic value. The harvested microalgal biomass can be converted into biofuel products, such as biohydrogen, biodiesel, biomethanol, bioethanol, biobutanol and biohydrocarbons. Thus, microalgal cultivation can contribute to CO_2 fixation and can be a source of biofuels. This article reviews the literature on microalgae that were cultivated using captured CO_2, technologies related to the production of biofuels from microalgae and the possible commercialization of microalgae-based biofuels to demonstrate the potential of microalgae. In this respect, a number of relevant topics are addressed: the nature of microalgae (e.g., species and composition); CO_2 capture via microalgae; the techniques for microalgal cultivation, harvesting and pretreatment; and the techniques for lipid extraction and biofuel production. The strategies for biofuel commercialization are proposed as well.
