Stand-alone system for the purification of brackish water directly powered by photovoltaic solar energyThe Applied Electrochemistry and Electrocatalysis Research Group at the University of Alicante has developed an Stand-alone system for the desalination and disinfection of water by Electrodialysis (ED) and the necessary water pre- and post-conditioning steps. The developed system is sustainable and environmentally-friendly being directly powered by a photovoltaic solar plant without using battery racks. This new system substantially decreases both the investment and maintenance costs by eliminating the batteries. Also, it can be adjusted to be used in water from very different sources like seawater, brackish water wells, wastewater treatment plants, industrial processes water, etc. being of particular interest for remote areas isolated from the electric grid. The Research Group has a demonstration Pilot Plant with the capacity to produce up to 1m3 of drinking water per day. The Group is looking for companies interested in the commercial exploitation of this technology through licensing agreements and/or technical cooperation.

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.

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.

Land application systems for urban wastewater treatment of small built-up areasA Land Application Systems (Figure 1) is a plot area, sized according to the influent to be treated, which has forests installed and is irrigated with wastewater. The residual water partially evaporates and the rest is taken up by the roots of trees and filtered through the soil. Before application to the soil, it is desirable to introduce a primary treatment system, to remove coarse solids, sand, grease and solids. But these systems provide more than just simple purification, because while treating the water, we are also producing biomass with high economic value. Unlike conventional waste water treatment systems, no external energy input is needed, so the running and maintenance costs are greatly reduced. Furthermore, it is a robust technology and the operation is simple. This technology is therefore ideal for treatment of urban waste water from small towns, with strong flow oscillations.

Water resources and contaminant transport modellingWhy modelling? Numerical models are important tools in the study of water resources. They can help understand processes (and their importance) that occur in a certain geological context. The rapid progress in the development of numerical models and computer hardware has improved simulation capability to an extent where we can routinely develop basin scale models. One of the main driving forces for hydrogeological model is the need to assess water supply potential of aquifers. Over the past 20 years, however, the emphasis has shifted from water supply problems to water quality issues. This means that while formerly the focus was almost exclusively on developing methods to assess and measure the water-yielding properties of aquifers, now the focus is largely on transport and dispersion processes, retardation and degradation of chemical contaminants. Numerical models are also applied to describe and interpret the reactive processes affecting contaminant transport through the porous media during laboratory-level experiments.
