The invention relates to a method for the dewatering of sludge on a screen, wherein a flocculant is admixed with sludge, whereafter the sludge is at least partially dewatered, the flow behaviour of the sludge on the screen being optically detected and the amount of flocculant to be admixed being set according to the free screen surface in a control region. The invention is primarily characterized in that the control region is arranged at a point of the cleaned screen in the inlet area of the sludge, for example at the edge. The invention also relates to a device for the dewatering of sludge, comprising a flocculant feed device and a screen downstream of the flocculant feed device, wherein a device, in particular a camera, is provided for optically detecting the flow behaviour of the sludge and is connected via a control system to the flocculant feed device for regulating the amount of flocculant, said device being characterized in that the device (11), in particular the camera, is designed such that it detects a control region in the inlet area (10) of the cleaned screen. In this way, regulation can be achieved for an optimal feed amount of flocculant in a straightforward manner regardless of the material feed and the sludge type.

In the recent years due to tremendous development and integration of renewable energy resources in Europe, hydraulic turbines and pump-turbines are key technical components to contribute to renewable energy production and to compensate for the stochastic nature of the variable energy sources, preserving thus the electrical grid stability. As a result, the overarching objective of the project is the enhanced hydropower plant value by extending the flexibility of its operating range, while also improving its long-term availability. More specifically, the project aims to study the hydraulic, mechanical and electrical dynamics of several hydraulic machines configurations fresh and seawater turbines, reversible pump-turbines under an extended range of operations : from overload to deep part load. A two-pronged modelling approach will rely on numerical simulations as well as reduced-scale physical model tests. Upon suitable concurrence between simulations and reduced-scale physical models results, validation will take place on carefully selected physical hydropower plants properly equipped with monitoring systems. To address this ambitious research plan, a consortium has been assembled featuring three leading hydraulic turbines, storage pumps, reversible pump-turbine and electric equipment manufacturers, SME, as well as world-renowned academic institutions. Extensive tests both on both experimental rigs and real power plants will be performed in order to validate the obtained methodological and numerical results.

This proposal aims to develop high-potential novel and environmentally benign technologies and processes for post-combustion CO2 capture leading to real breakthroughs. The proposal includes all main separation technologies for post-combustion CO2 capture; absorption, adsorption and membranes. Enzyme based systems, bio-mimicking systems and other novel forms of CO2 binding will be explored. For each technology we will focus on chosen set of promising concepts (four for absorption, two for adsorption and two for membranes). We aim to achieve 25% reduction in efficiency penalty compared to a demonstrated state-of-the-art capture process in the EU project CESAR and deliver proof-of-concepts for each technology. The various technologies and associated process concepts will be assessed using a novel methodology for comparing new and emerging technologies, for which limited data are available and the maturity level varies substantially. Based on the relative performance using various performance indicators, a selection of two breakthrough technologies will be made. Those two technologies will be further studied in order to do a more thorough benchmarking against demonstrated state-of-the-art technologies. A technological roadmap, based on a thorough gap analysis, for industrial demonstration of the two technologies will finally be established. HiPerCap involves 15 partners, from both the public and private sectors (research, academia, and industry), from 6 different EU Member States and Associated States, and three International Cooperation Partner Countries (Russia, Canada, and Australia). The HiPerCap consortium includes all essential stakeholders in the technology supply chain for CCS: power companies, RTD providers, suppliers, manufacturers (of power plants, industrial systems, equipment, and materials), and engineering companies.
