Research Projects

SolarSpring is connected with a big network of research institutes.  We are supporting and are active in a number of national and international research projects.

Recent research projects

SWINGS Project

SWINGS project (titled "Safeguarding Water Resources in India with Green and Sustainable Technologies") started in September 2012 due to the interest of implementing integrated and optimized solutions for wastewater reuse in different areas of India. A consortium of 10 partners from Europe and 11 partners from India, consisting of R&D, companies, SME, NGO and local body organisations with complementary expertises to improve the water reuse and sanitation in developing regions in India using low cost, easy to adopt, sustainable and zero discharge methodology based on biological and natural systems.

SolarSpring  joins the european-indian consortium of SWINGS to supply India with clean water. At a time with an urgent need to conserve water resources, efficient sanitation systems,  water recycling and re-use  play a key role in sustainability. They can ensure that the vital resource Water is recovered from waste and can be re-used at the same time as protecting human health and the environment. In particular, the SWINGS project will enlist already optimized municipal WW treatment concepts and combine "green" and sustainable technologies. The result will be enhances water recycling and re-use, decreased energy consumption, and production of useful by-products from the process as secondary resources. Thus, treated WW will be transformed to soil enrichment resource, to irrigation water, to aquaculture farm feed, via sustainable sanitation that safeguards the local drinking water supply in India. 
The starting point of the SWINGS project will be anaerobic digestion (AD) and constructed wetlands (CW) that will be configured with environmentally sustainable disinfection technologies.

The research leading to these results has received funding from the European Union Seventh Framework Programme (FP7/2013-2015) under grant agreement n° 308502.

REAPower targets an innovative concept based on the reverse electrodialysis technology. This technology consists of the extraction of the “osmotic energy” from two salt solutions showing a large difference in salt concentration, what is called salinity gradient power (SGP). 

For fuelling the process, constant supply of two water streams with a salinity difference is necessary. Up to now, SGP research focused mainly on the combination of fresh water as the low concentration solution and seawater as the high concentration solution. However this approach has important disadvantages as the low salinity water increases the electrical resistance.

The objective of REAPower is to prove the concept of electricity production through SGP-RE using brine and sea or brackish water and to develop the necessary materials, components and processes.

PRODES - Promotion of Renewable Energy for Water production through Desalination

ProDes supports the use of renewable energy (RE) in remote areas where the electricity grid cannot accommodate high penetration of intermittent energy sources. The project focuses on Southern Europe where desalination is an increasingly important energy demand factor. Using renewable energy to power desalination, either in stand-alone or grid connected systems, will allow better load control and consequently wider renewable energy use in these areas.

MEDIRAS - Membrane Distillation In Remote Areas

The MEDIRAS project will optimise a solar desalination system and demonstrate its cost effectiveness and reliability. The modular system set-up is based on the innovative Membrane Distillation (MD) technology. MD is favourably applicable for small distributed desalination systems in the capacity range between 0.1-20 m³/day. The technology is very robust against different raw water conditions and is suitable for operation with renewable sources, like solar energy.

GreenLysis - Project

The main objective of the GREENLYSIS project is setting a pilot plant in order to demonstrate the technical feasibility of reducing both the energy consumption and the environmental footprint of a WWTP, producing hydrogen and oxygen via electrolysis by renewable energies.
