Universidad de Alicante posted this: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.

Paloza LLC posted this:Smart heavy metal scavenger materials and technologyWe developed smart heavy metal scavenger material that can remove heavy metals such as Pb2+, Hg2+, Cu2+, Ag+ etc. After removing the heavy metal ions, the material can be regenerated for reuse. The synthesis process of the material is well established and the material can be synthesized in large scale. We now look for users or large companies that can market our materials and technology for us.
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.
UATEC - Unidade de Transferência de Tecnologia posted this:Process for converting waste, effluents and organic by-products in recyclable materialsA group of researchers from a Portuguese university has developed a biological process to treat waste, effluents and organic by-products with industrial origin characterized by high biodegradability that adds value to conventional biological treatment processes, integrating their assumptions on the concept of biorefinery. The invention aims to reduce by 96% the organic matter content of the starting substrate allowing generally meet the discharge criteria set out in the legislation.

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: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.
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.
IMDEA Water Institute posted this:Membrane technology and Transformation of disposed reverse osmosis membranes into recycled membranesMembrane technology is the generic term used for any separation process in which membranes are employed. A membrane can be defined as a physical barrier separating two phases and allowing a selective transition of compounds from one phase to the other. The part that goes through the membrane is the permeate and the part that is rejected by the membrane is the retentate (Figure 1, Membrane technology separation scheme). Membrane technology can be applied for purposes such as: • Water purification: undesired impurities are removed from the solution. For example: soft water production by removal of calcium and magnesium cations • Concentration: required components are present at a low concentration and the solvent is removed. For example: concentrating fruit juice by removing water • Fractionation: a mixture must be separated into two or more desired components. For example: milk fractionation in the dairy industry Membranes can be classified depending on the compounds that membranes are able to separate (Figure 2, pressure driven membranes).
UATEC - Unidade de Transferência de Tecnologia posted this:Biopolymer based micro- and nanoparticlesA group of researchers from a Portuguese university developed a method for preparing new hybrid materials based on biopolymer and silica, in the form of spherical particles with uniform size and smaller than 1 micrometer for a number of applications in environmental and industrial areas. The method is also effective for coating nanoparticles of variable nature, with a thin shell (tens of nanometers) with composition identical to the hybrids. The materials have been successfully tested in the removal of chemical species in water at laboratory scale, in particular in the removal of organic pollutants dyes and pharmaceutical compounds. Other applications are being considered. The University looks for companies working in the environmental, pharmaceutical or biotechnology areas, or companies in the area of materials for licensing and / or future collaboration in developing new formulations and testing new applications.
