The objective of this study was the development and design of a treatment system at a pilot-plant scale for the remediation of hydrocarbons in industrial wastewater. The treatment consists of a combined approach of absorption and biodegradation to obtain treated water with sufficient quality to be reused in fire defense systems (FDSs). The plant co...

Wastewaters polluted with hydrocarbons are an environmental problem that has a significant impact on the natural ecosystem and on human health. Thus, the aim of this research was to develop a bioreactor sorbent technology for treating these polluted waters. A lab-scale plant composed of three 1-L bioreactors with different sorbent materials inside...

Biofouling significantly reduces the performance efficiency of membrane bioreactors due to the colonization and accumulation of a matrix of microorganisms. In order to investigate the effect of ultrasonic frequency on biofilm formation and bacterial ecology at different frequencies, four microfiltration membrane modules were subjected at 0, 20, 30...
Article
Biostimulation of the activity of degrading autochthonous microbiota constitutes one of the most accepted bioremediation tools for oil-polluted soils. Applications of nutrients such as nitrogen fertilizers, oleophilic fertilizers or surfactants are some of the strategies employed. Soil microcosm experiments were performed in open glass containers t...

This paper introduces the WINDRO_LIFE Project, a research project supported by European Union´s LIFE Programme. The WINDRO_LIFE research project responds to the need to supply desalinated water to zones which have no access to fresh water and energy sources. The project's main objective is the construction of a prototype installation ("pilot") for...

This study describes the capacity of different sorbents to form stable biofilms under highly hydrocarbon-polluted conditions and the degrading capacity of the microbiota present in the biofilm. With this aim, microcosms were designed in a 1 L beaker with 400 mL of culture medium or polluted wastewater and an amount equivalent of 200 mL of the selec...
Article
Extracellular polymeric substances (EPS) are one of the main components of microbial biofilms, which are markedly influenced by the chemical composition and functional properties of these EPS. This study quantified the adherence capacity of 29 bacterial strains isolated from marine water in LuriaeBertani and Bushnel-Haas culture media. Their capaci...

This study investigated autochthonous microbial responses and hydrocarbon degradation in a sandy soil artificially contaminated with Diesel fuel at 20,000 ppm using NPK fertilizer and Ivey surfactant as biostimulating agents. Experiments were carried out at pilot scale at different moisture contents. Dehydrogenase activity and CO2 production, measu...

The use of solvents in desalination processes limits the use of certain materials in the construction of the reverse osmosis membranes. Therefore now the research effort has focused on improving new materials. In particular, nano-structured materials will probably form the basis for new reverse osmosis membrane materials. This study makes a review...

Reverse osmosis is currently the most important and commonly used desalination technique. The objective of this paper is to review the history of reverse osmosis membranes, to outline the current state of the art and insight into the tendencies being. The current market of RO membranes is focused on thin-film composite polyamide membranes, which ar...

Mechanical Transmission System Integrated into a Wind turbine for Water Desalination and Depuration by Reverse Osmosis. http://www.lifewindro.eu/ The project’s main objective is the construction of a prototype installation (“pilot”) for water desalination by reverse osmosis. The innovation of this system is its ability to work selfsufficiently, using only the mechanical energy generated by a wind turbine adapted to transmit directly this mechanical energy to high pressure pumps of the reverse osmosis system.
