We develop, design and fabricate filtration systems for solid/liquid separation in the processing industries as well as Vibratory Mixers and Single-Use Technologies.
Sophisticated, highly automated and fully enclosed filtration systems for either wet or dry discharge, or alternatively for semi or fully continuous thickening. System benefits include high efficiency solids removal, precious metals (catalyst) recovery, patented heel volume filtration, cake washing, cake drying and in-situ cleaning of the filter media. DrM filters are routinely used in many industries including oil & gas, petrochemical, specialty chemical, fine chemical, environmental, mineral and metal processing, pharmaceutical, as well as food & agrochemical. Amongst candle filter suppliers DrM has proven to be one of the most versatile and flexible to adapt to any client request.
The FUNDABAC® Filter excels where large quantities of solids are involved. The filter is an enclosed equipment where the operator and the environment is protected from the process liquids. However, when it concerns smaller batches operators may be looking for alternatives with manual operation and batch-wise replacement of elements. Cartridge type filters usually fall into this category. However, they pose a containment risk when the housing is opened and the cartridges replaced.
The FUNDASHIELD fills this gap and addresses containment issues during the change of cartridges. The filter elements are enclosed in a plastic bag and isolated from the environment. For installation the complete bag is placed within the pressure housing. However, the process fluid is not in contact with the housing. Instead, the bag is directly connected to the process piping and only the filter internals are exposed. When the housing is reopened for replacement of the bag, the operator does not get in contact with any potentially hazardous fluids.
The filtering membranes are arranged in modules which vibrate vertically while keeping the liquid feed stationary. The relative velocity changes direction many times per second and creates turbulence on the membrane surface, thereby minimising the fouling layer. The vibrating mass is reduced to a minimum which also minimises the required energy input. The resulting heat input is significantly lowered and even for temperature sensitive products cooling may not be required.
The FUNDAWAVE® handles the feed solution very gently as no large circulation pump is needed. A conventional circulation pump can damage cells, molecules or other sensitive substances during operation and by eliminating the circulation pump the FUNDAWAVE® is the most product gentle industrial scale MF and UF system available. Additionally, the elimination of the circulation pump produces uniform trans-membrane pressures throughout the unit and results in the sharpest membrane cut-offs of any industrial system.
The FUNDAWAVE is a new filtration concept which targets applications that so far could not give satisfactory results with any type solid/liquid separation equipment. The equipment is based on the crossflow principle with membrane-based filtering media adapted to specific filtration duties. The flow rate is maintained by constantly removing the solids layer forming on the membrane. In contrast to standard tangential flow filtration equipment (TFF) the crossflow is accomplished by movement of the filter membrane across a stationary liquid.
The FUNDAWAVE is an industrial crossflow filtration solution specifically targeted for applications where flux rates, capital investments, gentle filtration conditions, energy consumption and sanitary design play an important role. It continuously delivers low fouling filtration by keeping the media clean by vibrating shear forces.
