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.

IMDEA Water Institute posted this: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.
Universidad de Alcalá-OTRI posted this:Bioremediation strategy in situ for the precipitation and immobilization of uranium and other toxic elements in contaminated soils.A research group from the Geology Department of the University of Alcalá is developing a technology to study the role of the oxidation-reduction processes of humics in the reduction of uranium and other toxic metals in contaminated soils to determine whether stimulating the activity of humic-reducing and oxidizing microbial communities in contaminated soils can be an effective strategy for the in situ immobilization of uranium and other toxic metals. The group is looking for technical cooperation projects with companies.
Universidad de Alcalá-OTRI posted this:Treatment by ozone of water polluted by pesticides and other organics pollutants from agricultural activitiesA Spanish research group from Analytic chemistry and Chemical Engineering department of Alcala University has developed a technology based in a process with ozone to treat water polluted by pesticides and other organics pollutants from agricultural activities. With this process is possible to eliminate both the original pollutants and the intermediate products, producing the complete mineralization which allows a reuse of these waters. The group is looking for marketing agreement with technical assistance.

The group looks for licencing agreements and commercial or collaboration agreements with pharmaceutical and petrochemical industry, and those industries in charge of the fertilizer preparation and production of compounds for the treatment of environmental problems.
Universidad de Cádiz posted this:An improved fast and high throughput method for the sequential measurement of nitrate and nitrite in water samplesWe have developed an improved fast and sequential protocol that permits the determination of low concentrations of nitrite and nitrate in aquatic samples using small volumes. It is ideal to analyse large sets of samples with different characteristics, since it is enough a small amount of water the volume and cost of reagents and consumables are reduced.
UATEC - Unidade de Transferência de Tecnologia posted this:Magnetic nanobeads for purification applicationsThese nanobeads combine high surface area, high affinity to metal ions and magnetic features. By merging these properties in one platform, these nanobeads provide a faster and less expensive method for the separation and enrichment of specific proteins, often present in biological media in very low concentrations, compared to conventional methods such as metal-ion affinity chromatography.
UNIVERSIDAD DE ALICANTE posted this:New catalyst that eliminates efficiently chlorinated volatile organic compounds in gaseous streamsThe new mixed oxide catalyst of cerium-praseodymium (CexPr1-XO2) allow the efficient combustion of chlorinated volatile organic compounds (especially 1,2-dichloroethane). These new catalytic systems are able to work in gas streams at temperatures between 250-500 º C in an dynamic and continuous way without suffering a significant deactivation process. In recent years, environmental legislation has restricted the air emissions permissible levels, and particularly the emission of volatile organic compounds (VOCs) harmful for both the environment and human health There is a wide variety of VOCs, of different chemical nature (aliphatic, aromatic, oxygenated and halogenated compounds) and consequence of different emission sources (waste gases from chemical plants, soil and water decontamination, solvents evaporation , etc..), but 1,2-dichloroethane (DCE, C2H4Cl2) is the most lasting, dangerous and commonly used in industry (used, for example, massively in the process of polyvinyl chloride production and consequently chemical plants produce significant amounts of waste that require efficient treatment). Until a few years ago, VOCs were usually eliminated by thermal incineration. However, new legislation on VOC emissions has originated significant improvements on treatment technologies. This is the case of the catalytic oxidation that in recent years has shown its ability to destroy VOCs at temperatures below those used in thermal incineration and has also produced a significant reduction of secondary pollutants (nitrogen oxides). Currently, catalytic oxidation processes require heating large gas flows that contain a small amount of VOCs and put the gas in contact with solid catalysts that can either be • Those containing noble metals as active phase: they have a excellent oxidation efficiency, although their cost is very high and gradually lose their activity with the presence of chlorine in the reaction mixture. • Those containing transition metals: they have a lower cost and are more stable and durable, although less active than those containing noble metals.
Centre Technology Transfer CITTRU posted this:Hybrid photocatalysts based on nanoclays for water purification (environment-friendly method of water purification)Water contamination becomes a problem, which may limit civilization progress. The development of a universal and inexpensive method of water purification is very difficult, because it may contain pollutants of different nature, e.g. heavy metals, organic compounds (pesticides, chlorinated aromatic compounds, antibiotics and surfactants) as well as bacteria. The water purification methods currently in use are based on osmosis, ion-exchange, adsorption, ultrafiltration, distillation and photooxidation. Although multifarious, they have limitations, mainly connected with their high power consumption and low efficiency.
