Solar desalination plant for sea water, waste water or brine A new system of seawater desalination has been developed, consisting of a solar heat collector made of a transparent film surface in a pyramidshaped tent and another dark one (to retain the maximum amount of heat) material inner truncated pyramid parallel to the former, generating a layer of heated air. Heat accumulates at the vertex, where high temperatures are achieved. This allows the evaporation of seawater injected by micronebulizers, resulting into moisture-laden air being pulled by a central axial tube leading to a 'cold spot' located underground. Here a network of galleries, filled with the stored water, provides cold temperature to dissipate heat and to condense the steam into pure water. Partners to further develop the technology and/or to establish commercial agreements along with technical cooperation are sought.

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.

Evidence-based knowledge of the Aral sea for the development of socio-economic strategies based on an understanding of natural processes in the region in the past, present and future The results obtained by the research team are exceptionally new and have no analogues in the world. They significantly clarify the fundamental knowledge about the Aral sea and provide scientific grounds for a new vision of social, economic and political prospects for the development of the Aral region. The researchers have a vision of the directions of further research to clarify the identified aspects of the evolution of the Aral region. The advantages of the offer are as follows: - These studies are connected and can be used in various scientific and applied disciplines, including economically and socially significant. - Deep knowledge of the evolution of water resources in Central Asia can be a political and economic tool, as well as knowledge about the development of civilizations in the region, supplied by archaeology.

Formulation of dry scrubber with 80% H2S absorption capacity The formulation has been repeatedly tested in a laboratory, yielding an absorption capacity of > 80 g H2S/100 g product (using ASTM D6646). I am looking to find a company in the gas/air phase treatment industry that is keen on taking this product to the market. Given its superior absorption capacity, the operational costs are significantly lower than its competitors. Please contact me to further discuss.

Test for rapid quantifying Legionella in waters (1 hour) (Legipid) based on Immuno-Magnetic Separation (IMS)Advanced immunosensing for determination of Legionella in water scenarios. Friendly packaging. Validated and certified technique. Proven technology with available successful cases on both preventative and outbreak situations, supported by scientific and technical papers. Immuno-Magnetic Separation (IMS) requires the sample to be prepared according to the concentration step from ISO 11731:2017. There is an environmental test kit available for the detection of Legionella spp. which attaches microscopic magnets to live bacteria in order to enable detection. The result can be crudely measured by a colour change, or more accurately with the use of a photometer. This method can be advantageous in field laboratories which do not have the facilities to handle the growth and disposal of hazardous micro-organisms.

Stand-alone system for the purification of brackish water directly powered by photovoltaic solar energy The 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.

New procedure for the purification of water contaminated by metals and the respective systems The 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.
