Centre Technology Transfer CITTRU posted this:The method of mass culture of the rotifers LecaneThe subject of the offer is the method of intensive, quick and cheap mass culture of Lecane rotifers. Lecane rotifers bred according to this method can be used in limiting the bulking of activated sludge in wastewater treatment plants or as food for fry, predatory tardigrades and predatory fungi. They could be also used as material for scientific research (eg. toxicological and/or ecological research, research of evolutionary processes).
Centre Technology Transfer CITTRU posted this:Biological method of reducing excessive growth of filamentous bacteria in activated sludge in wastewater treatment plantsThe subject of the offer is a biological method of reducing excessive growth of filamentous bacteria in activated sludge in wastewater treatment plants. The invention uses organisms naturally occurring in the activated sludge - rotifers, which eliminate filamentous bacteria that cause bulking of activated sludge - one of the most prevailing and most serious problems in sewage treatment plants
Fundació URV posted this:Catalytic wastewater treatment for organic matter removalThe catalytic technology allows you to remove high concentrations of COD (40.000-200.000ppm) at atmospheric pressure. All kind of organic compunds are removed (biodegradable and non biodegradable ones). The catalyst life is around 2-3 years. It is an exothermic process, so the energy needed for the process is just for the start up. The process works at 250-350ºC.
UATEC - Unidade de Transferência de Tecnologia posted this:Graphene oxide macrostructure for the removal of heavy metals from contaminated watersA group of researchers at the University of Aveiro developed a graphene based material capable of removing mercury from contaminated water. The invention consists on the functionalization of three-dimensional structures of graphene in order to increase the affinity to mercury, the subsequent encapsulation in a permeable casing facilitate its removal from the aqueous medium. The main advantage of this system lies mainly in their high mercury removal efficiency, ease synthesis process, low cost and the possibility of its application in locations that do not have specific infrastructure.

UNIVERSIDAD DE ALICANTE posted this:Wastewater treatment by electrocoagulation (EC)The Department of Physical Chemistry (Applied Electrochemical Group LEQA) at the University of Alicante has a high experience and know-how to develop and carry out the removal of pollutants in wastewaters by electrocoagulation (EC). A pilot plant fully equipped with the necessary infrastructure and with ability to treat 100L/h of wastes is available in order to develop the pre-industrial phase and scaling-up of these processes. This technology could be of interest to several industries: chemical, tannery, textile, etc. Innovative aspects of the tecnology: - The EC cell is controlled electrically and have no moving parts, thus requires less maintenance - The EC process avoids uses of chemicals and so there is no problem of neutralizing excess chemicals. - EC produces effluent with less total dissolved solids (TDS) content as compared with chemical treatments.
