Reduced filtration Cycle Times |
|
Conventional filter presses filter only 75-80% of the batch in the first 50% of the cycle time. If the plate stack is opened before the full cycle is complete, the result is a wet, sloppy cake. |
A Membrane Filter Press, however, can be stopped at the most efficient point in its cycle. By applying pressure to the membrane built into the filter plate, the cake is squeezed to achieve final solids content in a significantly reduced cycle time. |
|
Increased Cake Dry Solids |
|
Membrane Filter Presses improve cake washing by initiating a low-pressure pre-squeeze before the wash cycle is begun. This pre-squeeze eliminates channeling (cracks and less well-formed areas of the cake) and produces a uniform, homogeneous filter cake and optimum wash efficiency. |
|
Improved Cake Wash Capability |
|
By applying a high pressure squeeze to the filter cake you produce the final cake with solids content from 50 to 100% greater than can be achieved with conventional filter presses. This is important for either maximum yield, where a high value liquid is your product, or high solids-content, where reduced moisture in the final cake is critical. |
 The membrane squeeze plate is offered to suit up to 16 bar squeezing pressure. Due to additional liquid extraction during the squeeze cycle, solid percentages increase. Filtration cycle time are reduced compared to the conventional recess chamber plate (Plate and frame) filter press, resulting in Benefits of membrane plates v/s chamber plates. Conventional type filter presses are limited to using feed pump discharge pressure to produce dry solids, resulting in longer cycle times.
The membrane squeeze plate reduced the long packing cycle by introducing a squeeze medium in to the center of the membrane squeeze plate. This allows the membranes to flex against the cake, compressing and packing it. Filtration cycle are shorter, dry solids are increased, and waste volume is reduced. |
| This membrane is designed to de water the most difficult sludge and protects the plates against potential cake less chambers. |
The high pressure membranes were developed for difficult filtration processes. Extreme squeeze pressure is possible due to the combination of the special feed inlet design and selected special materials. |
