Filter plates and frames
For pressure filtration at low pressure levels.
Membrane filter elements –
for shorter cycles and higher solids content
As the inventor of the membrane filter element (1973), we continuously advance membrane technology. LENSER membrane filter elements significantly accelerate your filtration process. They increase dry solids content while simultaneously conserving resources.
This is achieved through mechanical post pressing directly in the chamber – precision fit and efficient.
We develop and manufacture:
- KM bloc – standard, welded
- KM UM bloc – empty chamber, welded
- KM UM HD bloc – high pressure element, welded
- KM RUM – with replaceable membrane half
- KM RUD – with replaceable membrane flap
KM bloc
The recessed membrane allows a more uniform cake thickness and a very good washing result.
Advantages
- Shorter filtration cycles
- Shorter washing times
- Higher dry solids content
- Even cake thickness distribution across filtration area
- Higher throughput rate
- Reduced water consumption
- Reduced air consumption during blow-drying
- Superior cake washing/blowing results
KM UM bloc
The UM bloc version is characterized by a bar row in the edge area that is stepped to double the nap height. It convinces with a particularly high operational reliability, as the UM membrane also tolerates a squeezing in an insufficiently filled or empty filter chamber.
Advantages
- Shorter filtration cycles
- Shorter washing times
- Higher dry solids content
- Higher throughput rate
- Reduced water consumption
- Reduced air consumption during blow-drying
- Superior cake washing/blowing results
- With stepped bar row in the edge area
- Suitable for repressing into a little filled or empty chamber
KM UM HD bloc
High-pressure membrane filter elements are characterized by their high load capacity. Thanks to special inlet designs and material combinations, these filter elements can withstand squeezing pressures of up to 30 bar.
Advantages
- Shorter filtration cycles
- Shorter washing times
- Higher dry solids content
- Higher throughput rate
- Reduced water consumption
- Reduced air consumption during blow-drying
- Squeezing pressure up to 30 bar
KM RUM
Exchangeable membrane filter elements are an efficient and cost-effective solution for maintaining your filter press equipment. In the case of worn elements, it is not necessary to replace the complete filter plate, but only the membrane - the basic body remains intact.
With the KM RUM type, the membrane halves are fixed to the carrier plate by means of clip strips. These designs allow easy and problem-free replacement of the membrane.
Vorteile
- Shorter filtration cycles
- Shorter washing times
- Higher dry solids content
- Higher throughput rate
- Reduced water consumption
- Reduced air consumption during blow-drying
- Exchangeable membrane for cost and time efficient maintenance
- Easy exchange of the membrane half
KM RUD
Exchangeable membrane filter elements are an efficient and cost-effective solution for maintaining your filter press equipment. In the case of worn elements, it is not necessary to replace the complete filter plate, but only the membrane - the basic body remains intact.
With type KM RUD, the membrane are fastened in the designated mounting grooves of the basic body by means of clamping strips. Please note that the KM RUD type can only be used as LENSER Mixed Pack.
Advantages
- Shorter filtration cycles
- Shorter washing times
- Higher dry solids content
- Higher throughput rate
- Reduced water consumption
- Reduced air consumption during blow-drying
- Exchangeable membrane for cost and time efficient maintenance
- Easy exchange of the membrane half
- Only as LENSER Mixed Pack
How the membrane process works
Unlike pure pressure filtration with chamber filter elements, membrane filter elements feature a flexible filtration layer known as the membrane. After the filling phase, this membrane can be mechanically expanded outward – for example using compressed air or water.
This allows the filter cake to be post pressed evenly across the entire surface. As a result, cycle times are significantly shortened while dry solids content is increased.
During the washing phase, the membrane stabilizes the filter cake by applying constant pressure. Subsequent post pressing after washing further increases the solids content – without the need for prolonged air drying.
