Membrane presses - Import export

The AQUACHEM LCM 320 (pocket press membrane) is ideal for mobile deployment on site on a suitable trolley and can be operated with up to 15 bar loading and 15 bar membrane squeezing. This machine can also be used as a testing filter press in the case in order to decide on the right fabric or to check the filterability of the suspension. Fully equipped, this compact press can manually implement functions that our fully automatic machines can do. The AQUACHEM LC 320 (pocket press chamber) is identical in design to the LCM 320 and differs only in its function as a chamber filter press (without membrane). The LC 470 is the more affordable, low-cost version of the EC-series. Main feature is the restriction of the feeding pressure to 7 bar. All other features are the same as the EC-series. This series is built in a compact design with a feeding pump and discharge manifold.

The AF filter presses from AQUACHEM are a further development of conventional chamber filter presses, which have been tried and tested in the industry for over a century. However, due to the degree of automation required and the increase in efficiency necessary nowadays, the technology we have had up until now is often no longer up to date. The design of the AF filter presses is based on the optimum interplay of the ?? individual assemblies of the filter press to ensure reliable, efficient and permanent operation without personnel being present. The automated flexibility of the product enables autonomous adjustment to changing conditions, such as concentration or even specific filter properties. We guarantee these properties and also availability. This is only possible because AQUACHEM and the AF-series possess the knowledge, an intelligent control system and the technology for maximum flexibility. Yes, this is a product with unique selling points – test it out yourself.

Our testing filter presses for hire are available in various sizes. Whether in a container or as a mobile filter press, we're sure to find the right solution for you. Set-up and connection of the systems is easy to perform, and we are of course ready to assist you with commissioning.

The Husky 307 diaphragm pump with type number D31211 has a pump tube and balls that are made of acetal, the diaphragms and seats are made of teflon. These Husky 307 double diaphragm pumps are ideal for pumping chemical liquids. These can be liquids such as paint, thinners, glues and, for example, polluting liquids. Because this pump is provided with two pump chambers with a common inlet and outlet, a continuous vacuum can be created by a linear movement of the diaphragm, whereby a ball valve ensures that the material can be further pressed. The membrane pump has a maximum pump capacity of 25 ltr/min and can handle a maximum working pressure of 7 bar.

For sophisticated decorative materials Press laminating is mainly used to process materials that are unsuitable for vacuum processes, such as textiles, materials with and without foam backings or non-stretchable cover materials like leather or Alcantara. Processing these materials requires high quality tooling and machinery to ensure the quality of the grain, the soft touch and the color remain intact. The decorative element and the substrate are usually laminated together by being pressed between two hard instruments. Precise decor positioning and tool arrangements ensure optimal laminating conditions. Other forms of laminating include leather laminating and membrane laminating, which combines press laminating, edge folding, trimming.

Membrane filter presses have a great influence on the dryness of the solid by using membrane technology in the filter plates. Compared to conventional filtration processes, it achieves the lowest residual moisture values in the filter cake. This makes the membrane filter press a powerful and the most widely used system. IF TIME AND DEGREE OF DEWATERING ARE CRUCIAL Depending on the degree of dewatering, different dry matter contents ( – percentage by weight of dry material in filter cake) can be achieved in the filter cake by squeezing with membrane plates. The range of achievable dry matter contents extends from 30 to over 80 percent. Membrane filter presses not only offer the advantage of an extremely high degree of dewatering; they also reduce the filtration cycle time by more than 50 percent on average, depending on the suspension. This results in faster cycle and turnaround times, which lead to an increase in productivity.

The hot filter press combines the standard process steps of a membrane filter press, (filtration, filter cake washing and squeezing), with the additional function of a thermal filter cake drying (TCD). As a result, all process steps are carried out in one plant, the hot filter press. Dewatering and drying of the resulting filter cake is thus done without a downstream drying process. Cost-intensive and time-consuming vacuum contact drying is therefore no longer necessary. FUNCTIONAL PRINCIPLE OF THE HOT FILTER PRESS – WITH THERMAL FILTER CAKE DRYING In contrast to the conventional method, the system consists of membrane filter plates and heat exchanger plates, which are installed alternately in a filter press. For thermal drying, hot steam and/or oil is applied to the working space behind the membrane and the filter cake is thermally dried accordingly. The advantage of this process is that a high dry matter content (DM content) of over 90% is achieved.

CellTRON® FOR MAXIMUM FILTRATION REQUIREMENTS The basis of this plant is a membrane filter press. The new product series is equipped with an innovative filter press emptying system with lifetime error message, an automated filter cloth washing system with implemented CIP cleaning function as well as an automatically opening and vacuum-proof housing. In contrast to conventional filter presses, this new development guarantees an almost gastight encapsulation of the filter press. The filter press thus meets the specific requirements for dewatering special (metal) sludges. In addition to standard configurations for battery cell production, this technology series is also suitable for demanding applications that require the highest safety and efficiency standards. These include volatile, dust explosive products as well as substances with toxic and radioactive properties but also pharma food products and hot suspensions (≥130°C).
