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.

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.

All the materials for realizing the invention (chemical reagents and equipment etc.) are commercially available. - It is not requirement the use of toxic flammable solvents to ensure the safety of personnel conducting the test. - The use of appropriate materials, allowed to simplify and shorten the work, to improve the reproducibility of detection and reduce the cost of detection procedure. - To achieve sensitive detection method allows subjecting the examination of much smaller volumes of liquid samples in comparison with that provided by the USEPA protocols (United States Environmental Protection Agency).
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:Permeable reactive beds for groundwater recharge with reclaimed wastewaterAt IMDEA Water Institute, in association with the Alcalá University and the Rey Juan Carlos University, we implement Permeable Reactive Beds technology as a wastewater reclamation treatment for application in artificial groundwater recharge activities. This technology is considered an in situ passive treatment, based on reactive materials which act as a filter for the water that goes through it. The filter retains or sorbs the chemicals, improving the water quality. This technology is the result of combining two well-known remediation techniques: SAT – Soil Aquifer Treatment and PRB – Permeable Reactive Barrier) (Fig.1). The main contribution of Permeable Reactive Beds technology is that it includes several layers of different reactive materials (natural or artificial), forming a horizontal barrier, so that the pollutants are removed from the water and are retained or modified by the solid phase through physical, chemical and/or biological processes (including precipitation, sorption, redox and degradation). Many parameters have influence over these processes, such as pH, redox potential, concentration or temperature. Permeable Reactive Beds can be settled either on the ground (superficial setting) (Fig. 1b) or in a trench (dug) (Fig. 1a). This horizontal position ensures reclamation of the water that flows through the bed.
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).
