TL;DR: Available publications on various disinfectants and disinfection processes used for the inactivation of Legionella bacteria were reviewed and oxidizing disinfectants were found to be more effective than non-oxidizing ones.

TL;DR: Experimental results showed that as biomass accumulates in the reactor, the available area for the contaminant to diffuse into the biofilm decreases causing a drop in removal efficiency.

TL;DR: It is demonstrated that in a gas-phase aerobic biofilter, nitrate can serve both as a growth-controlling nutrient and as an electron acceptor in a biofilm for the respiration of VOCs with low Henry's constants.

TL;DR: The field of industrial ecology focuses on reducing the environmental impacts of goods and services, on systems-based analysis of environmental problems, and on innovations that can significantly improve environmental performance Industrial ecology has significant potential for US environmental policy But to establish a firm foundation for significant policy initiatives, there is a need for better understanding of the potential and limitations of a range of promising approaches.

TL;DR: In this paper, the United States Environmental Protection Agency has proposed new categorical pretreatment effluent standards for the Metal Products and Machinery Industry, which are more stringent than current discharge limits in the automotive industry.
