Plate and Frame
The Plate and Frame Filter Press Plates, the original filter press concept in technology, is still a trusted solution in many industries today. This traditional design consists of filtration chambers formed by alternating plates and frames – the frame forms the chamber where the filter cake is developed. The suspension fills up the chambers while its filtrate is drained through Spigot / Cock / Nozzle on filtration plates so that it operates through pressure filtration. These are a great option when there is less interest in volume but more emphasis on filtration area as well as highly viscosity slurry such as specialized processes like Paper Industry, Viscose & Staple Fiber Filtration, Edible Oil, Commercial Oil Filtration and many more.
Key Features
- Classic Design: The old plate-and-frame designs are still valuable in many filtration operations especially when accurate control of surface areas is necessary.
- Customizable Cake Thickness: For specific applications, frame plates that determine the thickness of a filter cake can vary from 10 to 50 mm hence offering customization flexibility.
- Versatile Material Options: It is also available in high-performance polypropylene (HP/CP) material which can be applied up to 80°C resisting most chemicals.
- Variable Pressure Range: It works within a pressure range of 4 to 8 bars quite effectively thus providing an ability to deal with different types of suspensions or filtration needs.
Advantages
- Excellent Washing Results: Symmetrical cake chambers result into equalized washing leading to compactly built and even slabs.
- Easy Maintenance: Less downtime for changing filters as it simplifies exchangeability of cloths.
- Cost-effective Filtration Media: While this system supports economical one-way filters lowering operation costs further,
- Flexible Cake Thickness: Can be changed simply by switching over filter frames hence they offer versatility required for various kinds of filtering.
Filtration Process
A classic process based on pressure principle characterizes Plate and Frame Filter Press. In this case, the suspension is pumped in to chambers where filtration media directly forms filter cake on it. At some point, as pressure increases within the chambers, dewatering of the cake takes place with subsequent collection of filtrate separately. This type of filtration is very efficient and gives good washing results resulting to uniform and properly shaped filter cakes.
Customization Options
Therefore, Plate and Frame Filter Press can be customized for specific operating requirements in terms of frame thickness, material options and pressure ranges. This attainment ultimately ensures that a broader range of applications becomes compatible with the systems hence increasing coverage across industries through effective filtration.
