The demand for water in Germany is increasing and used water is not being utilized sufficiently. Graywater in particular, i.e. wastewater from showers, bathtubs and washbasins, offers great potential for further use. It can be brought to service water quality on site and reused for flushing toilets or watering gardens, for example. Thanks to flexible 3D textiles, it can even be used in almost any building to save space.

Around 50 to 80 percent of all domestic wastewater is graywater. Until now, large containers and tanks have been needed to reprocess it and return it to the cycle, taking up a lot of space in the building. The German Institutes of Textile and Fiber Research Denkendorf (DITF) and their project partner ARIS have developed a biological, textile-based system.

It is based on a 3D spacer fabric made of highly durable polypropylene. Its advantage is that it can be installed flat and is therefore extremely space-saving. Thanks to its special system geometry, it can be installed in places that would otherwise remain unused - for example in a new building under the floor of an underground garage, on a flat roof or in the garden. It can be modularly adapted to the water requirements and structural conditions in the respective buildings. "Even vertical solutions on facades are conceivable," explains DITF scientist Jamal Sarsour. This means that the graywater treatment system could be used in densely built-up cities in particular.

The system developed by the project partners requires little maintenance and is therefore particularly cost-effective. Compared to previous solutions, it is characterized by a long lifespan. It therefore contributes to sustainable water use and makes a valuable contribution to the circular economy.

ARIS plans to launch the new textile-based graywater treatment system on the market in 2024.

The project will be presented on June 13, 2024 at the SME Innovation Day of the Federal Ministry for Economic Affairs and Climate Protection in Berlin.

The research project with the number 16KN080829 of AiF Projekt GmbH, Berlin, was funded by the Federal Ministry of Economics and Climate Protection as part of the Central Innovation Program for SMEs (ZIM) on the basis of a resolution of the German Bundestag.

Focus on eccentric screw pumps and pumps for shear-sensitive materials

Improved productivity and increased lifespan and tailored solutions also for the most demanding applications within the chemicals and plastics industries and in PUR applications – these are the convincing arguments with which Oerlikon Barmag is showcasing its precision metering pumps at this year’s ACHEMA between August 22 and 26, 2022 in Frankfurt. The focus is on the new pump for shear-sensitive conveying media and the new eccentric screw pump.

Eccentric screw pumps – robust all-rounders convey any medium
The requirements for pumps are considerable, as the demand for customized solutions for increasingly complex processes is rising. This is particularly true for Oerlikon Barmag’s new eccentric screw pump range. High wear-resistance, increased durability and robust operation – the new pump is tailor-made for conveying highly-filled, high-viscosity and abrasive media, such as filled adhesives, filled silicones and filled casting compounds, for example. The is the multi-stage seal system, which considerably increases the pump’s lifespan. The upstream shaft sealing ring protects the slide ring seal against excessively-fast wear caused by challenging media. In turn, the optimum alignment of the drive shaft – ball bearing-supported and centrally-guided through the shaft sealing ring – prevents any metal debris caused by friction and hence ensures considerably greater durability. Producers benefit from considerably greater productivity, as the pumps’ maintenance intervals and hence machine downtimes are significantly reduced.

New pump for shear-sensitive materials
For increasingly complex customer-specific process solutions, Oerlikon Barmag is now expanding its GA series, developed especially for the challenging conveying of high-viscosity media, to include the GAB51F for shear-sensitive conveying media. The newly-developed pump with its viscosity range of max. 300 Pas is tailored to conveying high-viscosity, shear-sensitive materials such as adhesives and silicones, for example. “The shear forces impacting the medium within the pump are reduced to a minimum as a result of a specially geometry”, explains Thorsten Wagener, Senior Sales Manager within the Pump Construction business unit. The material is conveyed through the pump in an as gentle and low-pulsation manner as possible and metered precisely at the outlet – ensuring it retains its characteristic properties.

High-speed metering pump with sealed product space
The high-speed metering pump has been especially developed for metering poorly-lubricating media. Here, the main benefit is the sealed product space, which extends the pump’s lifespan considerably. The space that comes into contact with the media is limited to the area around the gears. “As a result, the high-speed pump is particularly suited for applications in the chemicals industry, which frequently involve aggressive acids”, comments Thorsten Wagener.

GM series for low-viscosity media
The pumps in the GM and GA series provide precision metering with low-pulsation feeding of the conveying medium. The multi-stage GM pump conveys low-viscosity media (i.e. 250 bar, 100 mPas) even under high pressure and in the most challenging conditions. The square design from the proven GM series is the standard pump for many metering tasks. The development of the multi-stage pump expands the applications range for the GM series considerably. The round 2-stage GM pump has been developed especially for use in high-pressure technology. It masters the particular challenge of conveying small throughputs with low viscosities. The pump is perfect for 0.05 through 20 cm³/rev feed sizes and is excellently suited for use in high-pressure machines for PUR molded parts, foam slab stock, refrigeration unit insulations and sandwich panels, for example.

GA series pumps for high-viscosity media
The Oerlikon Barmag GA range has been especially developed for the challenging conveying of media with higher viscosities. The GA series pumps are available for conveying volumes of between 1.25 and -30 cm³/rev (0.6-144 l/h). They have been designed for pressures of up to 200 bar, for viscosities of up to 1.500 Pas as well as for temperatures of up to max. 225 °C. With this range of pumps, Oerlikon Barmag offers its customers tailor-made solutions for many technical processes in which high-precision and even metering is of paramount importance.

The drum pump – conveying and metering using a single unit
With the drum pump, the Oerlikon Barmag pump specialists have created a pump designed specifically for conveying and metering high-viscosity materials such as adhesives, silicones and other high-viscosity materials from drums and other large containers and for pressures of up to 250 bar. Its special features not only include the fact that it removes high-viscosity materials from the drum, but that it also meters the medium directly without any additional interim stops.

At first glance, rowing boats, the Airbus 380, safety equipment and stadium roofing have very little on common. They receive their specific properties as a result of the use of special fibers, among other things: aramid fibers and carbon fibers are processed into special yarns that are frequently deployed as compound materials. These fibers are growing in demand as the world seeks to reduce its reliance on fossil fuels; new solutions are required to reduce weight and replace heavy metallic parts.

Aramid fibers are produced in a highly-chemical process that is extremely aggressive; the acrylic precursor used to manufacture carbon fibers is a different process, but again no less difficult. In these sophisticated processes, the gear metering pumps are not only responsible for the high-precision control of the melt transport; durability, resistance within aggressive environments and cost efficiency also play decisive roles.

Special materials for special tasks
The process, the expected pump lifespan and the maintenance frequency are the decisive factors for choosing the materials from which the pumps and their components are manufactured. For optimum results, Oerlikon Barmag offers solutions that intelligently combine the various materials and the latest technologies. Whether in the case of surfaces with ceramic coatings, gears and shafts featuring DLC coatings, pumps made from cobalt alloys (StelliteTM) or robust and durable Oerlikon Barmag hybrid constructions comprising zirconium oxide ceramic and duplex stainless steel – the high-precision ZP- and GM-series pumps are design-optimized depending on the intended use. Various seal systems and customized drive concepts round off the pump program.

Kelheim’s premium tampon fibre Galaxy® has proven effective in sanitary pads: It can substitute up to 70% of the synthetics in ADL (Acquisition-Distribution-Layers) in feminine hygiene pads. The amount of feminine hygiene waste is enormous – and often the time it takes for these products to degrade is hundreds of years longer than the lifespan of the woman who used it, because the synthetic components are not bio-degradable. Changing consumer behavior drives the need for environmentally friendly yet safe alternatives.

The viscose hygiene fibres from Kelheim offer significant ecologic advantages: they are made from cellulose, which means they are based on renewable wood and they are fully biodegradable. These fibres are manufactured exclusively in Germany, in one of the most environmentally friendly plants worldwide.

Galaxy® in sanitary pads offers not only a benefit for the environment. Due to its excellent wicking and absorption capacity it conducts liquids quickly and efficiently away from the body and leaves a pleasant feeling on the skin – in other words, it does exactly what the ADL layer is made for. In addition, Galaxy® helps to distribute the liquid evenly in the absorbent core enhancing so the overall performance of the pad.

“Plastic must disappear from these single-use products. The substitution of single synthetic components in sanitary pads is the first step”, says Dominik Mayer from the Bavarian fibre expert’s R&D team. “Down the road we want to offer a completely bio-based solution for sanitary pads and for various other hygiene applications.
