Pioneering mesh designs presented byGKD – Gebr. Kufferath AG at Filtech. Whether for water processing in large industrial plants or continuous vacuum belt filter systems in the environmental and mining industry: At the leading international trade fair for filtration and separation technology, the company once again highlights its integrated solution competence for filter media and process belt solutions in Cologne. With its special mesh structure and seam technology, the Vacubelt filter belt range guarantees efficiency and safety in exacting dewatering processes. In process water filtration with particles larger than 500 μm, the relatively new spiral fabrics produced are also in high demand. Alongside large-format mesh samples, the knowledge of process requirements that the filtration and process belt specialists have gathered over many years makes them sought-after contacts for discussing specific issues and solution models.
In view of the growing global demand for phosphorous, potash, and lithium, expanding extraction capacities and improving production efficiency are critical to the success of the global mining industry. This is where the different belt types of the Vacubelt range, made of polyester monofilaments, are able to make a vital contribution. All Vacubelt filter belts share the core characteristics of robust transverse stability, low crease formation, smooth surface, good cake discharge, and excellent cleaning behavior. What’s more, their improved seam design contributes to greater process reliability. Its minimal opening at the seam means that the extremely flat PAD seam reduces particle penetration. The company further decreases this seam opening by inserting filling threads, thereby further lowering the risk of particle penetration. These filler threads are supplied with the belt and inserted before the clamps are closed. This means that there is no need for the flaps required by other manufacturers. The advantages of the firm seam design are clear: wipers are not stressed by partial raised sections and the seam itself is also subject to less wear.
For dewatering of phosphogypsum, the firm offers three thermally treated single-ply vacuum filter belts specifically designed for particular processes and applications in the form of the belt types Vacubelt 3354, 3356, and 1003. With air permeability of 200 to 350 cfm and mesh apertures of 150 to 340 μm adapted to the respective plants, they guarantee constant high dewatering performance. As such, these belts in widths of up to 4.35 meters and lengths of up to 70 meters fulfill the highest service life and dewatering requirements.
In potash fertilizer production, the Vacubelt 5060 filter belt has proven its worth many times over. With apertures of up to 470 μm and air permeability of 290 cfm, this belt type reliably withstands the high temperatures and corrosive conditions that are typical of this process.
The Vacubelt 2015 filter belt has been the globally established standard in the field of FGDP gypsum dewatering for many years. The small aperture of 50 μm – coupled with air permeability of 55 cfm – justifies its superiority over conventional belts for dewatering the gypsum suspension produced during flue gas desulphurization. Faster dewatering, greater pore density, less tendency to clog, thermal resistance, and very good cleaning properties make the Vacubelt 2015 belt type the vacuum filter belt of choice for both new systems and retrofitting existing power plants.
The same belt type is currently also setting new standards in lithium dewatering in vacuum drum filters.
In cooling lubricant filtration, the robust Vacubelt 3354 filter belt made of polyester wires is a proven alternative to the usual polypropylene products available on the market. This belt type reliably retains swarf and particles abraded from the grinding wheel without the addition of filtration aids, even with thin filter cakes.
In industrial laundries, the spiral fabrics that GKD produces entirely in house are becoming something of an insider tip for process water treatment with particles larger than 500 μm. Thanks to their unusually high performance, this product range, which made its debut at last year’s Filtech, is therefore also recommended for all other filtration processes requiring similar separation performance to washing water treatment in industrial laundries.

Pack life science and healthcare products
Securely, flexibly and efficiently
Medical devices and sensitive products place the highest demands on pack quality and secure packaging processes. Since the trend in the medical sector towards greater product individualisation, complexity and variety continues unabated, leading increasingly to ever smaller batch sizes, Multivac will be presenting at Medtec Live 2020 a number of flexible solutions for packing small product series reliably and efficiently. Another focus at the trade fair will be identification and inspection systems, which make a major contribution to higher levels of product and patient safety.
From its traysealer range Multivac will be showing the semi-automatic T 260 traysealer, which was specially developed for the high demands of the medical devices industry. The features of this compact machine are its precise temperature control and distribution, as well as its highly controlled sealing pressure, and it therefore offers the maximum level of pack quality, reproducibility and process reliability.
Other exhibits include the C 300 TC chamber machine, which enables sterile products to be packed very securely in pre-made pouches. All models of the TC series are equipped with a temperature-controlled and permanently heated sealing bar, which means that the processes can be calibrated and validated. The user-friendly machine control offers a wide range of software options, such as for example the reading of production data.
Another trade fair highlight will be the presentation of an identification and inspection system, which makes a significant contribution to meeting the statutory requirements for patient safety. The UDI regulations (Unique Device Identification) require medical products to be marked and identified uniquely. The MDR (Medical Device Regulation) also redefines the role of the manufacturer or distributor, who is now responsible for the integrity of the medical product up to the point of use.
The R 245 thermoforming packaging machine, which is capable of being freely configured, will be used to demonstrate the product marking and the visual inspection of the print image. This highly flexible machine model can be used to securely pack a wide range of batch sizes in many different formats and packaging materials. It can also be equipped very easily with other system components, such as for example automated handling modules.
All the machines to be shown at the trade fair are cleanroom-compatible, and they meet all the statutory requirements as well as the GMP, GAMP5 and ISO guidelines.

Packaging machines for small to medium-sized batches
Using a special exhibition area (in front of Hall 5), Multivac will be showing at interpack a range of simple and needs-based solutions for packing products in small and medium-sized batches. These enable hand-craft businesses and smaller processors to make the entry into automatic packaging – with the aim of achieving maximum efficiency and optimum product protection. In addition to various chamber machines of different sizes, the exhibits will also include a compact thermoform packaging machine and two traysealers.
When it comes to packing in film pouches, Multivac will be presenting its complete product range, consisting of tabletop, free-standing, double chamber and chamber belt machines. Thanks to their wide range of equipment options, the machines can be adapted to the individual requirements of the customer, and this makes a major contribution to maximum process efficiency.
In addition to the semi-automatic T 060 traysealer, Multivac will also be exhibiting here its automatic T 300 model, which will be used at interpack to produce Multi Fresh vacuum skin packs.
The range of compact thermoforming packaging machines will be represented by the R 105 MF, which is designed for producing high-quality Multi Fresh vacuum skin packs. At interpack this machine will run Multivac Paper Board, a paper fibre-based carrier material, which has a sealing medium specially designed for the Multi Fresh skin film, enabling perfect pack results to be achieved.

Climate-Neutral Energy Generation
Producing Biogas from Waste and Sludge
At this year’s Ifat, the world’s leading trade fair for environmental technologies, which will be held in Munich, Germany, from 4 to 8 May, biogas plant manufacturer Weltec Biopower will again present its anaerobic digestion plants for industrial and municipal use. In Hall A4, at Booth 508, the internationally renowned biogas specialists will provide information on all topics concerning the use of organic waste and sludge for the production of energy.
The reference projects for the digestion of waste and the production of biomethane, which is equivalent to natural gas, include the Weltec plant of the French potato chips manufacturer Altho, whose chips brand Bret’s accounts for one third of the French market. Every year, the plant in St. Gérand, Brittany, produces about 1.75 million standard m³ of biomethane from 22,000 t of production waste in the form of potatoes and starch as well as sludge from the internal wastewater treatment plant. This amount of the climate-neutral energy source corresponds to the gas consumption of a town of 5,000 inhabitants.
Altho benefits greatly from the biomethane production, which enables it to use its leftovers in a sustainable manner and cut greenhouse emissions. The annual savings amount to approximately 3,900 t of CO2eq. This corresponds to the emissions that more than 2,000 persons would cause with a flight from Munich to New York.
For the energy plant, Weltec has implemented process technology that is both innovative and reliable: The mix of solid and liquid substances is first pre-processed and homogenised in order to ensure efficient digestion in the stainless-steel digester. The entire process is fully automated and controlled by a PLC unit. With the help of the membrane processing, the biogas is then transformed into biomethane.
“Custom-tuned biogas technology is a must”, says Jens Albartus, Director of Weltec Biopower. “Usually, anaerobic digestion plants will only encounter technical problems if the process technology does not meet the requirement profile.” For this reason, plant operators and investors should opt for a provider who has experience with various substrates and climate conditions. In its projects, Weltec custom-tailors its plants so as to ensure stable, economic operation. In more than 300 planned and implemented biogas projects in 25 countries, the specialists have gained a wealth of experience with diverse framework conditions.
Regardless of whether sludge, abattoir waste or production leftovers are used as raw material, Weltec thus guarantees a high energy yield. This is achieved with the right blend of expertise, smart processes and custom-tailored supervision by biologists and engineers.
