Membrane filter 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.

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 RO installation, also known as "Reverse Osmosis" or "Reverse Osmosis," is a membrane filtering process that removes particles from water, such as germs and viruses, as well as salts (ions). The resulting water is referred to as demineralized or demineralized water. As a result, demiwater (desalinated water) ensures exceptional water purity for a wide range of applications. It's used to make boiler feed water, make-up water, cooling water, and/or process water, among other things.

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).

The filter presses from AQUACHEM of the EC Beverage series are used in the beverage industry, for example, for the filtration of selected wines. Another feature is that the filter elements are gasketed, and therefore the must or juice does not also come into contact with the ambient air. The EC Beverage series is offered as standard in the filter plate sizes 470, 630 and 800 mm.

In the tried-and-tested, gasketed design, the EC-series offers many benefits to the user on top of its ease of operation. Due to the internal drainage, use in even the most hygienically clean areas is possible. The press lock is performed by an automatically self-regulating pneumatic/hydraulic closing system. The automatic closing pressure maintenance ensures that the plate pack always remains closed. An adjustable pressure switch with a potential-free contact is provided for integration into the customer's control system. This prevents the feeding pump from running uncontrollably. Also, as with all AQUACHEM filter presses, the discharge manifold can be generated here at the customer's request. Due to the gasketed design, the seamless backflushing of the filter media in the filter press is possible. The filter press frame is phosphated and powder-coated, offering a high level of protection against external influences.

The BC-series impresses with its simple and robust technology, while at the same time offering the user many features to simplify work. The optionally available semi-automatic plate shifting allows the user to shift the filter elements conveniently. The hydraulics are controlled via the HMI control system with touchscreen. This allows any feeding pump of your choosing to be integrated and controlled. There are plates available in the formats 800, 1,000 and 1,200 mm, allowing for filtration surfaces of up to 178 m². Thanks to the gasketed design, a clean environment is ensured, even during the internal flushing of the filter elements with aggressive media. The individual discharge manifold enables many functions such as displacement air drying, turbid flow, clear flow, flushing and also cake washing. The standardised hydraulic unit is used in both the BC-series and the AF-series.
