Abstract:

Using the granular microalgae – bacteria mixed consortium biotechnology use for wastewater treatment can answer multiple stringent environmental and wastewater treatment needs addressing at the same time the circular economy objectives. The process provides a high quality wastewater treatment effluent while having low energy requirements (there is no need for aeration systems) and creating favorable conditions for increased resources recovery (both water and residual biomass). The project’s aim is to provide a

sustainable biotechnology that supports the circular economy requirements and leads to reduced environmental impact by tackling the key downsides of conventional biological wastewater treatment processes. Microalgae-bacteria induced granular system can ensure

increased wastewater treatment performances with quick and efficient microalgae-bacteria biomass separation (within minutes) by a simple and rapid settling stage. Using this approach, the project fundaments the possibility of implementing an alternative and innovative biological process, thus supporting the concept of sustainable wastewater treatment by: complying to the strategy of reducing operating costs (eliminating aeration cost), targeting the global strategy on reducing greenhouse gas emissions by capturing the carbon dioxide resulted from aerobic biodegradation of organic matter and targeting wastewater treatment plants operators strategy concerning waste management as the residual microalgae-bacteria biomass can be used for resources recovery.

Abstract:

This project proposes creation of a low-cost working tool by correlating the response given by specialized sensor arrays with the evaluation of ripening, senescence, alteration of fresh fruits and vegetables. The sensors proposed for the architecture of developed devices for appreciation of changes in the controlled atmosphere in the storage spaces will measure the variation of CO2 content, O2, VOC and the relative humidity as efficient tools in discriminating the complex volatile mixtures produced by fresh fruits and vegetables. At the same time, basic phytochemical characteristics of the plant structure are evaluated such as antioxidant activity, total sugar content, phenols, terpenoids, tannins, lipids, acidity and enzymatic activity to establish patterns of ripening, respiration, transpiration and alteration processes. In parallel with recording of the sensor response, a qualitative and quantitative evaluation of the atmosphere of storage spaces will be made using techniques such as respirometer experiment, and other instrumental techniques. The technologies based on semi-selective gas sensor platforms for VOC, relative humidity, O2 and CO2, also called electronic noses (EN), seem to be a promising alternative for appreciating the way of storing fresh fruits and vegetables.

Abstract:

The concept of this project is represented by the identification of new approach method of the electrical machine insulations and an innovative technological procedures to the insulation improvement.

The insulation of the electric machines represents a main component which can to influence the functional parameters.

In the past few decades, it has been recognized that the safety margins in the design were

excessive and can greatly increase the cost of the rotor and stator. For example, Draper has

indicated that a 20% reduction in the groundwall insulation thickness in a large SCI motor

stator will allow the width and the depth of the stator slot to be reduced, for the same output

power.

Depending on the speed of the motor, the weight of the steel needed for the stator is reduced from 13–33%, the copper is reduced 5–64%, and the mass of the insulation is reduced 12–57%.

These are significant reductions. Since the price of a motor or generator is very dependent on the mass of the steel, copper, and insulation, the stator cost is significantly reduced by increasing the design electric stress level, i.e., by reducing the groundwall thickness.

The research team (partnership) proposes a research project with the main objectives:

• New procedure of the insulator used in electrical machines.

• Knowledge of the oxidative thermal degradation of the electric machine insulating material in the absence and presence of an effective antioxidant;

• Determining/identifying the optimum concentration of antioxidant or synergic mixture that hinders the material thermal degradation.

• Improving/bettering/upgrading the insulation characteristics (impregnating varnishes) by adding antioxidant additives, polymeric materials and new technological procedures.
