Many work processes produce dirty water - which in turn can lead to process disruptions. BELKI Filtertechnik offers solutions to enable trouble-free work. Messe.TV visits a company with a history dating back to 1888. Holger Tausendfreund shows what the products can do and explains their special features.
Dirty water disrupts processes - but Belki has come up with a few ideas to ensure that processes run smoothly. Simone Dericks: Hello Mr. Tausendfreund, hello to you! We are now with you at the Belki company.
Holger Tausendfreund: We are a company that specializes in reconditioning and filtering production fluids in factories. Starting with grinding machines, lathes, washing baths and washing systems. We treat these with the filter technologies we have. Starting with oil separation, magnetic field traction, paper belt filters, in other words a whole wide range of filter technologies. Simone Dericks: Yes, these are two very important pillars for you: The oil separator and also these central systems. What makes your company so special? Holger Tausendfreund: We have different sizes of oil separators. This is the type 211 H we call it. This is our smallest device. It is suitable for cleaning bathroom surfaces in the order of 1-2 square meters. The special thing about our appliances is that they are a complete in-house development. We have an electrically operated diaphragm pump in this appliance. The purpose of this electrically operated diaphragm pump is to remove the liquid that is drawn off the surface as gently as possible using such floating systems, because we do not want to re-emulsify the oil in the pump chamber. So you can see this very clearly here. The oil droplets that are drawn away from the surface really do end up there. This has the great advantage that we get a very fast and very effective oil separation, so that we do not need large surfaces that unnecessarily pollute the cooling lubricant, the washing liquid, the grinding water. We remove the oil very quickly.
Simone Dericks: You just said that this is your smallest machine. In what sizes do you have such an oil separator? Holger Tausendfreund: This is the smallest, which can extract 25 liters per hour from the surface and we go up to sizes of 2000 liters per hour, but these are quite large separators. We have also built systems of up to 6 cubic meters, for example at the hazardous waste landfill site, where the aim was to remove oils from the leachate. Simone Dericks: You said special sizes, i.e. do you also manufacture customized units for your company? Holger Tausendfreund: We also manufacture individually - that is also one of Belki's strengths, that we don't necessarily sell off-the-shelf products, but that we really work on solutions together with the customer - so that we can really achieve an optimum result together with the customer, tailored to the production process. I can show you a few things using the video. Simone Dericks: With pleasure. Holger Tausendfreund: In the video, we have a few examples of various central systems that we have built. This is a classic grinding application, for example - you can see a system here with a scraper tank and a hydrocyclone. Or here is an automatic magnetic belt filter. In other words, the solutions that are actually used in grinding to eliminate solids very quickly and effectively. What we want is to use simple means to effectively optimize the processes using physical forces and remove the foreign matter from the liquids accordingly. A simple example is grinding, for example, if you use a hydrocyclone, which simply uses centrifugal force to separate the solids from the liquid. A very simple process based on physics.
Simone Dericks: The Belki central systems - what is special about them that makes them so unique for the customer? Holger Tausendfreund: Well, for the customer, we work with them to develop a customized solution. That means individually. We go into the plant, take a look at the process, look at each individual machine and try to have the best possible effect on removing the impurities, oils and solids so that they can then be transported to the central systems and cleaned there.
Simone Dericks: Belki was founded in 1888, that's a long time the company has been around, if you look to the future, where would you like to go? Holger Tausendfreund: Well, there are basically two things that are important to us. We have started to optimize the process even further by using our Belki Check system to effectively measure concentrations, for example. We measure the pH value, i.e. we measure the critical parameters of the cooling lubricant and then automatically add more so that the same concentration is always present in the system and the machine. So that the customer always has the same conditions on his machine. That is one issue, and we have now gone one step further by developing this Belki Check system to such an extent that we can call up the data online and map the process - for example on the computer in our office and see exactly what is going on with the system. The same applies to the customer. If, for example, a fault occurs, they usually receive a signal, for example on their cell phone or computer, and know that they have to do something and intervene in the process again. Simone Dericks: Then I wish you every success and thank you for the interview. Thank you for having us here and have a great trade fair! Holger Tausendfreund: Thank you.
