Nitya Engineers are the manufacturers & exporters of Membrane Filter in India Punjab Ludhiana.
At NITYA ENGINEERS, we provide Membrane Filter Presses for the ultimate filtering solutions. The Membrane Filters are designed and developed with unique characteristics and inherit the latest technological features. The Membrane Filter Press technology is gaining increased acceptance because it reduces subsequent processing / disposal costs for the filter cake. In many applications the membrane filter press significantly reduces the residual moisture content, thus making this technology attractive for new plants and for upgrading existing facilities. A careful selection of plate and membrane material is very essential for the successful performance of the process.
Membrane Filter Plates are used to
- Reduce filter cake moisture content
- Reduce filtration cycle time
- Improve cake washing
There are two methods to install this membrane filter plates.
- A full plate pack
- Alternately in conjunction with recessed companion plates (More Economical option)
Membrane Filter Press Plates have a chamber below the drainage surface that can be inflated. The common method used is water pressure, which is generated by pumping into the squeeze cavity to inflate the face of the plate against the filter cake. Membrane Plates are used to reduce the cake moisture content & shorten the filtration cycle time.
Mix Pack Membrane are the most common configuration (one recessed plate then one membrane plate alternate in the press plate pack). Membrane Plates usually operate at a feed pressure of up to 7 bar and squeeze pressure up to 15 bar. Special plates can be designed for higher feed & squeeze pressure.
Replaceable membranes can easily changeable. Plate filling problems are minimized and use of a rubber Membrane enables "empty-chamber" operation without damaging the plate, resulting a considerable reduction in incidents of plate failure. Even if the chamber is not completely filled, the filter cake is squeezed by the inflating filter lever and therefore perfectly dewatered.
During the initial phase of the filtration cycle, so-called "fill and filtration" the process is similar to the chamber Filter Press. After reaching a predefined pressure, usually around 3 - 7 bar, depending on the sludge characteristics, sludge feeding is stopped & the rubber membranes are inflated using either water or air as squeeze medium. The cake is hereby compressed and dewatered further. Then the squeeze medium is relieved & the cake is discharged.
