Abstract:

The feasibility of installing biocidal beads into a catch basin filter insert for simultaneous stormwater disinfection and contaminant removal was tested. The catch basin filter insert (DrainPac®) was tested for its sediment, oil and grease, and coliform bacteria removal efficiency in conjunction with bench-scale testing of biocidal polymer beads. DrainPac® catch basin filters are composed of a metal frame, polypropylene filter fabric, and a high-density polymer support basket, and are installed below storm drains. A 12 x 41 in. DrainPac® filter (United Stormwater, Inc.) insert was set in

Abstract:

Biocides are widely used as a preservative or as an antiseptic agent in consumer care products such as toothpaste, mouthwash, and soaps, as well as in household cleaners and even in textiles due to their high antimicrobial effectiveness. The usage of this compounds results in discharge to wastewater treatment plants and so into surface waters. Their existence in the environment is of importance due to their negative effects on aquatic environment microorganisms and human health in terms of occurrence in surface waters and their fate in wastewater treatment plants. In this scope, this study foc

Abstract:

Legionella est une bactérie pathogène, ubiquitaire des environnements aqueux. L'utilisation des eaux de surface, par les centrales nucléaires, provoque un réchauffement de ces eaux, qui associé aux conditions de fonctionnement peut entraîner sa prolifération. Afin de limiter le développement de cette bactérie, en deçà des seuils réglementaires, EDF met en œuvre un traitement à la monochloramine dans ses circuits. Notre étude a eu pour but d’améliorer les connaissances sur les associations entre les légionelles et leur principal hôte : les amibes, et sur les facteurs susceptibles d’influencer l

Abstract:

The biological treatment of metalworking fluids (MWFs) is a cost effective alternative to conventional waste disposal processes. While research has proven that this process is capable of treating large volumes of wastes with high organic concentrations, there are uncertainties about the mechanisms by which the treatment occurs, and there are limitations that must be overcome. There is a need to understand the importance of the mechanisms by which carbon (and hence COD) is removed from the wastewater. This will allow for waste practitioners to make better decisions for optimizing the process, a

A adição de ácido sulfúrico ao inóculo é a prática mais utilizada no controle dessas bactérias, contudo é uma substância de baixa eficácia, que também afeta a levedura. Antibacterianos utilizados complementarmente devem levar em conta a seletividade; o espectro de ação; e ainda restrições em fermentações que utilizam

Abstract:

Conventional wastewater treatment plants are able to reduce contaminant loads within regulations but do not take into account emerging contaminants. Antibiotic resistance genes and antibiotic resistant bacteria have been shown to survive wastewater treatment and remain detectable in effluents. The safety of treated wastewaters is crucial, otherwise unregulated and unmitigated emerging contaminants pose risks to public health and impede wastewater reuse. This dissertation aimed to further understanding of emerging microbial threats, and tested two natural and low-cost tools for their mitigatio

Abstract:

Using seawater in cooling systems is a common practice in many parts of the world where there is a shortage of freshwater. However, biofouling is one of the major operational problems associated with the usage of seawater in cooling systems. Microfouling is caused by the activities of microorganisms, such as bacteria and algae, producing a very thin layer that sticks to the inside surface of the tubes in heat exchangers. This thin layer has a tremendously negative impact on heat transferred across the heat exchanger tubes in the system. In some instances, even a 250 micrometer thickness of fou
