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.

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.

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: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: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.
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).
