cpp ACHEMA PLANTS, APPARATUS, COMPONENTS What does ZLD stand for? Dr. Scholz: It stands for zero liquid discharge. Pusher, decanting and worm screening centrifuges perform important solid-liquid separation tasks in these systems, which are designed to recycle and reuse all waste water and simply discharge solid waste. We have all of these centrifuge types in our portfolio. We therefore hope to be able to secure as many orders in this sector as possible. I also believe there is great growth potential in the area of inorganic salts, namely in lithium production. Are you referring to the lithium boom? Dr. Scholz: Yes, precisely that. The demand for high-performance batteries is constantly increasing. One reason for that is growing e-mobility. Lithium is an important constituent of these batteries. Experts anticipate that the demand for lithium will quadruple to between 400 and 500 t of lithium carbonate equivalent in the coming five years. Which role do Siebtechnik centrifuges play in lithium production? Dr. Scholz: Lithium occurs naturally only in small concentrations and in combination with other mineral salts. Its extraction and isolation are complex and costly, and without high-performance solidliquid separation they are not even feasible. We are in a position to supply suitable machines for this purpose. And what about the polymer segment? Dr. Scholz: There we are profiting short-term from the rising demand in Asia for HDPE and PVC. Siebtechnik, with its large decant - ers, is very successful in this segment. I also think there is interest - ing growth potential in the field of organic compounds. I’m particularly referring here to the extraction of methionine and threo - nine. Demand for these amino-acids and their salts, which are used, for example, as additives in foodstuffs, is rising steadily. Our Turbo - screen series screening decanters with their additional filter stage have proved very effective for this. And lactose manufacturing PROFILE: DR. REINHARD SCHOLZ Dr. Reinhard Scholz was born in Berlin on 25 May 1962. After graduating in Process Engineering at RWTH Aachen University, he took a PhD in crystallisation. He gained his first professional experience in various positions at Messo Chemietechnik, a manufacturer of crys - tallisation systems, before moving on to Niro Prozess - technik, where he was company director. In 2005, he also took responsibility for GEA Messo GmbH, Duisburg. The next major career step followed in 2015, when Dr. Scholz was appointed the GEA Group’s Senior Vice President Separation Technologies. He was responsible in this capacity for all the Group’s technology-related activities in the areas of evaporation and concentration, crystallisation, distillation, membrane processes and vacuum technologies. Since January 2017, this experienced solid-liquid sepa - ration specialist has been a Director of Siebtechnik GmbH in Mülheim an der Ruhr alongside Dr. Jürg Pollmanns and Christian Steinhaus. remains a further important area of application for our worm screen centrifuges and Shortbowl decanters. Let’s talk next about the Chinese market. Siebtechnik has been very successful there in recent years. What does the future have in store for you in China? Dr. Scholz: Even if growth slows down, China is, and will continue to be, our most important export market. However, we also have our eye on other markets that we want to concentrate on. I am think ing here especially of the American market, which we have so far served via our US sales & marketing subsidiary, Tema Systems. Unfortunately, our American customers have not understood the split of work between Siebtechnik and Tema. This is shown, for instance, by the fact that our machines are only known there as Tema centrifuges. Our job is to ensure a uniform and transparent corporate image. Does that apply just to America at present? Dr. Scholz: No. It applies all over the world. International activities with our sales & marketing companies must be better coordinated, so that we are perceived externally as a single company. That will facilitate contact with the customer and help us leverage growth potential in our global markets. Finally, a word about Achema. Which new products will you be presenting at the show? Dr. Scholz: We shall be presenting an energy-efficient version of our SHS series pusher centrifuges. These machines consume about 15 % less electricity. Visitors will also have a chance to see our improved screening elements. Could you explain that, please? Dr. Scholz: Thanks to a special water-jet technology, we are able to produce screens that have a large free specific screening area and at the same time offer a high undercut. The latter ensures a considerably longer service life, especially when processing sticky products or products that tend to crystallise. We also want to demonstrate the service-friendliness of our screen baskets, which are made up of a number of screening segments. This now patented solution offers users various advantages when it comes to installation or de-installation, maintenance and storage. Will the new, uniform company image be a big talking point at Achema? Dr. Scholz: The Achema show offers a unique opportunity for this, of course, but there’s only a short time to go until then. www.cpp-net.com Online search: cpp0218siebtechnik Hall 5.0, Booth C72 THE INTERVIEW WAS CONDUCTED BY: LUKAS LEHMANN Assistant Editor-in-Chief 10 cpp 02-2018
GLASS FILTERS High quality material for demanding tasks: VitraPOR® glassfilter apparatuses made from pure borosilicate glass 3.3 fulfill many requirements in chemical and pharmaceutical labs as well as for industrial, biological and environmental technology applications. Properties such as heat resistance to over 500 °C and resistance to most acids, alkalis and solvents make our VitraPOR® glassfilters, which conform to international standards, suitable for use in many chemical, pharmaceutical and technical procedures. Custom VitraPOR® sintered elements according to your specifications are characterized by their neutral properties and open-pore structure. They are suitable for even the most unusual applications. VitraPOR® glassfilter apparatuses can be supplied in different pore size classes, from smaller than 1 micron to over 500 micron and as custom-made solutions in many shapes and sizes.
