University of Huelva posted this:New procedure for the purification of water contaminated by metals and the respective systemsThe invention solves the problems of inefficiency which usually shows the conventional passive treatment systems. The reactive fills developed for the removal of inorganic contaminants historically have focused on removing low concentrations of these (typical features of coal mining), however when these fillers are faced to high concentrations of metals (sulfur mining, uranium, industrial water waste…) quickly clogging and loss of reactivity occurs. The present invention allows the removal of metals without clogging and/or loss of reactivity. This is achieved by the use of a coarse inert material with high surface mixed with a fine-grained reactive material, so that the surface of the inert material is breaded with reactive material. Coarse fragments of inert material act as a frame, providing large pores that reduces clogging by precipitates. The small particle size of the reactive material provides a large surface area that increases its reactivity.
University of Huelva posted this:Procedure for obtaining a renewable resource of metals from acid minewater, and the respective systemsIs known in the state of the art the recovery of metals from the acid aqueous solution that contain them, generally by liquid-liquid extractions. For metals recovery at industrial scale is necessary that these metals can be recovered simultaneously by means of a single extraction step. There are several extraction reagent for this purpose, all these reagent are very expensive and the industrial process for the metal recovery (particularly for rare earth and yttrium) are very complex and finally expensive. The present procedure allows to recovery selectively metals (particularly rare earths and yttrium) by the neutralization of acid mine waters. The objective is to revalue the metal content dissolved in this waters.

University of Vigo posted this:Innovative process for the removal of persistent organic pollutants present in wastewater streams.This is the first time that surfactants-based aqueous phase segregation has been proposed for the remediation of aromatic organic pollutants. Up to know, biological degradation was used alone or in combination with other physical and chemical methods (e.g. volatilization, sorption, electrokinetic, oxidation, extraction with supercritical fluids, etc.), that often entail economic and environmental disadvantages. Therefore, the proposed strategy is an environmentally friendly alternative that entails benefits such as low energy consumption, low cost, availability of reagents at bulk quantities and easy implementation.
University of Vigo posted this:Procedure for sea urchin embryo cryopreservation and attached bioassayThis sea urchin (Paracentrotus lividus) embryo cryopreservation procedure with attached bioassay has been specifically designed for sea urchin blastula (8 hour development embryo) conservation in liquid nitrogen to be used as out of reproductive season biological supply. This protocol has applications in research, aquaculture and ecotoxicology. The process described is fully developed, from how to obtain blastula embryos from sea urchins, composition and concentration used of the cryoprotecting agent, cryopreservation procedure including the cryoprotecting agent addition and dilution methodology, the seeding temperature during freezing and including a post-thawing viability study The possibility of a sea urchin embryo biobank ensures not only the access to test organism embryos all year round but also access to these embryos in places where it was not possible before either for their distance to the ocean or for the lack of the necessary facilities to maintain reproductive adults in optimum conditions to breed. The development of the bioassay using cryopreserved sea urchin embryos will help overcome the seasonal constraints in application of bioassays to assess marine water quality.
University of Vigo posted this:New sustainable adsorbent for bleaching efficient industrial effluentsMany industries, such as those belonging to the textile, wine, and paper industry, consume huge volumes of water and, as a result, generate a large amount of contaminated water containing persistent colour pollutant compounds. These compounds represent an environmental and health threat due to their well-known associated problems, such as carcinogenicity, toxicity and mutagenicity. Furthermore, they entail a great environmental impact when discharged in aquatic environments, perceptible at very low concentrations, creating an undesirable visual impact, which, in many cases, does not meet the degree of conformity under the current directives on the wastewater treatment for industrial effluents (Directive 91/271 / EEC). The solution proposed by the research group Chemical Engineering at the University of Vigo, is the use as adsorbent of peat, or a similar lignocellulosic material, immobilized in calcium alginate beads. This process is efficient, cheap and environmentally friendly, unlike other processes and technologies. In fact, the utilization of peat instead of activated carbon as industrial adsorbent has the advantage that peat requires no activation, unlike activated carbon, reducing operating costs. In addition, the low cost of the adsorbent would be translated into significant economic benefits. Moreover, depending on the contaminant removed from the waste effluent, the exhausted adsorbent may be used as soil fertilizer at its end of life.

RAMOT at Tel Aviv University Ltd. posted this:High Voltage Photovoltaic Cells with High EfficiencyA novel photovoltaic cell is described for converting sunlight to electricity at higher efficiency relative to existing cells, and with improved flexibility for integration in modules, both one-sun and concentrating. The new cell contains many small sub-cells, which are internally connected in series. Such configurations are called Monolithic Integrated Modules (MIM) and they are capable of providing very high open circuit voltage. Our MIM design is based on a monolithic device with vertical PN junctions with significant expected advantages in performance relative to existing MIM designs: higher voltage; smaller contact area and no front metallization grid, leading to higher efficiency; better utilization of the solar spectrum; and better matching to integration in modules including concentrator modules. High-voltage cells can be electrically connected in parallel instead of series, leading to nearly independent operation (voltage-coupled instead of current-coupled) even under non-uniform illumination and even partial shading conditions. This will improve the overall performance of a photovoltaic system, and permit a less demanding and less expensive optical design. Project ID : 6-2011-180
IMDEA Water Institute posted this:Treatment of water from bentonite slurryWhy Does Water From Slurry Require Treatment? The problem arises once the slurry is used and subjected to the separation process by applying a filter press, in order to reuse the water to generate new slurry. The water, due to the loss of quality it suffers during the construction process, interferes with the proper functioning of bentonite, forming an unstable slurry, which tends to flocculate, and thus loses the necessary properties for application. Processing these waters entails a considerable environmental improvement, in addition to cutting operating costs by reducing water consumption and the dumping of effluent which, due to the physicochemical characteristics acquired, is not suitable for discharge under current legislation.
