nmp FILTER Press
| Bio Statement |
The safest way to inflate the membranes is to use water instead of air. If you are using air to inflate the membrane and you experience a tear, you run the risk of plastic breaking which can be extremely hazardous. However, if you use water and experience a rupture, you may end up with a water leak, which is much safer and easier to contain. A tank and pump are used to fill the membranes with water via the manifold piping which would be stainless, PVC or steel (depending on the application) and flexible tubing to connect the manifold to the plates. The water pumps into the membranes during the squeeze process and once that is complete, it is drawn back to the water tank for reuse. Membrane filter press 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. Even with partially filled filter chambers, excellent dry matter results can be achieved thanks to membrane technologies. This even applies with abrasive media, for example, pump wear is decreased by reduced feeding pressure (6-8 bar depending on the suspension) without affecting the final result. In order to ensure maximum protection of the membrane filter press, special safety systems are used for the various membrane inflation media. The membrane inflation medium consists either of compressed air or a liquid medium (e.g. water). As standard, squeezing pressures of up to 15 bar are possible and in special cases, these can be higher. Further information on squeezing with membrane technology can be found here.
