A hydrocyclone with an inflow region providing tangential inflow for a feed slurry and with a separation region following the inflow region with an underflow discharge pipe to carry off heavy materials and with an overflow nozzle in the form of an immersion tube projecting axially into the interior of the hydrocyclone. Another inflow is provided in the area of the tangential inflow to supply the barrier fluid, where the barrier fluid and the feed slurry are separated from one another by a lamella in the hydrocyclone before they are brought together. The separation region includes a conical section and a subsequent cylindrical section above the underflow discharge pipe.

A method for producing a fibrous pulp web, in which a fibrous pulp suspension is dewatered in a Twin Wire Former to form a fibrous pulp web which is dried with a TAD dryer. A pre-dewatering device with a hood and suction roll is provided after the Twin Wire Former and before the TAD dryer. The fibrous pulp web is guided through the pre-dewatering device between exactly two machine cloths. The machine cloth between suction roll and the web is a porous felt, and the machine cloth between web and hood is a structured wire. A volume flux of hot drying fluid greater than 100 m^(3)/(m^(2)min), preferably greater than 250 m^(3)/(m^(2)min,) is drawn through the fibrous pulp web into the suction roll.

The invention relates to a vertical screw press (1) for separating solids, e.g. fibres, from a suspension, e.g. a pulp suspension, having a cylindrical screening basket (9, 10, 11), and a press screw mounted rotatably in the screening basket (9, 10, 11) via a drive (2) and having a central screw shaft (12) and a, preferably double-flight, screw helix (13) arranged thereon and extending at least along a majority of the screw shaft (12), wherein an inlet (8) for the suspension, an outlet (6) for filtrate and a discharge (7) for the dewatered solids are provided. It is primarily characterized in that the cylindrical screening basket (9, 10, 11) is surrounded by a filtrate backlog container (3, 4, 5), consists of a plurality of parts as seen in the axial direction, and at least one part, preferably the bottommost part (5), has a filtrate backlog container having a larger diameter, wherein the rotatable screw shaft (12) can be embodied in a reversible manner, wherein the inlet (8) for the suspension is provided at the top end and the discharge (7) for the dewatered solids is provided at the bottom end, with the result that the feed direction of the screw press (1) extends from top to bottom and wherein an outlet (6) for filtrate is provided at the bottom end of the filtrate backlog container (5). This enables both efficient dewatering and ready accessibility for cleaning and maintenance without taking apart the entire machine.

The invention relates to a method for processing metallized packaging materials, in particular beverage cartons or blister packs. According to the invention, acid is used to dissolve the aluminum and separate same from the plastic material. The metal-containing solution of the acid is then subjected to a pyrohydrolytic treatment so as to recover the acid. The aluminum can be recovered as valuable alumina.

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.

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.

The EU has set the stage to empower semiconductor manufacturing in Europe being one of the key drivers for innovation and employment and creator for answers to the challenges of the modern society. Aim of IoSense is to boost the European competitiveness of ECS industries by increasing the pilot production capacity and improving Time-to-Market for innovative microelectronics, accomplished by establishing three fully connected semiconductor pilot lines in Europe: two 200mm frontend (Dresden and Regensburg) and one backend (Regensburg) lines networking with existing highly specialized manufacturing lines. Focus is the availability of top innovative, competitive sensors and sensor systems Made in Europe for applications in Smart Mobility, Society, Energy, Health and Production. Today competitors are already involved in the development of sensor systems for applications in the emerging Internet of Things. But there is a significant gap between those forces and the capabilities to bring ideas into the high volume market fast enough. IoSense will close this gap by providing three modular flexible pilot lines being seamless integrated in the IoT value crating networks and ready to manufacture each kind of sensor system prototypes. IoSense will increase the manufacturing capacity of sensor/MEMS components in the involved pilot lines by factor of 10 while reducing manufacturing cost and time by 30%. IoSense is designed to enable focused development work on technological and application oriented tasks combining with market orientation. Design to Market Needs will be accomplished by customer involvement, embedding all required functionality besides sensors. Finally, the time for idea-to-market for new sensor systems is intended to be brought down to less than one year. As a result, semiconductor manufacturing will get a new boost in Europe enabling the industry with competitive solutions, securing employment and providing answers to the upcoming challenges in the IoT era.
