Universitat de Girona posted this:OMBR - OMBReuse (MBR retrofit to OMBR)The proposed technology is a concept that combines OMBR (osmotic membrane bioreactor) with MBR (membrane bioreactor) in a single module therefore it reduces the difficulties of installation and simplifies the operation system. Thus, this technology would renew all or part of the existing systems without the obligation to increase the volume installed and associated civil engineering costs. The fact that the OMBR modules are designed like the MBR module allows using the two types of membrane processes in the installed system.

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.
Universidad de Alicante posted this:Production of briquettes for energy recovery of furniture waste with polyurethane foamsThe Research Group "Waste, energy, environment and nanotechnology" (WEEN) from the University of Alicante has developed a new compact material and a production process of briquettes of furniture waste. This process makes it possible to carry out the management and the energy recovery of this waste, avoiding the environmental problems associated with its landfilling and also making it easier to transport, handle and store. The briquettes obtained, show physicochemical characteristics similar to the conventional and they have a high energy density being able to be used as fuel for thermal power plants or industrial boilers. Companies in the waste treatment sector and the furniture industry that are interested in commercial exploitation of this technology through licensing agreements and / or technical cooperation are sought.

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.

This process can be easily integrated with existing pulp production, allowing even the subsequent exploitation of bark for energy production.
University of Granada (OTRI) posted this:Method for treating and obtaining sub-products from residues proceeding from olive millsUGR has developed a procedure for treating residues from olive mills allowing to obtain sub-products with high added value for industry, through the use of clean technologies, without addition of external solvents or other agents during the process avoiding to generate additional residues. Along with residues treatment, the revalorization of effluents is achieved as a potential and profitable source of high-value antioxidants in the market and agro-food, cosmetic, pharmaceutical and biotechnological industries.
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:Valorization of whey and vinasses by producing antimicrobial extracts using biotechnological processesThis invention is based on the production of antimicrobial extracts with potential application against pathogenic microorganisms. The biotechnological production of antimicrobial metabolites was carried out using Lactobacillus plantarum strains. Two industrial wastes, whey, and wine distilled lees (or vinasses) were assayed in order to make the process economically competitive with regard to the chemical one. The extracts are mainly composed by lactic acid, 3-phenyllactic and bacteriocins. Whey was enzymatically hydrolyzed and the solutions were fermented sequentially or simultaneously. The bioprocesses were carried out continuously or discontinuously
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.
Universidad de Alicante posted this:Method for recycling of vessels and other structures composed of fiberglass and resinResearchers at the University of Alicante have developed a method to recycle composite fiberglass structures on a polymer matrix (resin). The process removes the polymer matrix, recovering glass fiber which can be reused. The process is not aggressive with fiberglass. It takes place at room temperature and is able to recover all the fiberglass used. The method is industrially scalable and can be automated. Fiberglass composites and resin are widely used in the construction of boat hulls, tanks, wind turbine blades and many other applications. This method is a very important innovation for the sector and there was no effective method that allowed recovering and reusing these materials.
