The Clear melt from Melt Clarification System contains a lot of fine particles which increases the turbidity of melt as well as increases the ash content of final product.
The Deep Bed Filter is designed to remove the suspended solids from clear melt & operated with fully automation system.
It requires no filter aid and produces no sweet water, two significant financial advantages over existing form of filtration. It removes larger flocculated particles which can create the negative roll in pan boiling.
The Deep Bed Filter run with all automatically controlled according to the status of various inputs from level and pressure included in the filter station, e.g. Valves, Pumps & Air Blower etc.
In Multi Bed filters, the filtering media is packed bed of sands and silica papers of different sizes. "Pores" are formed in the interstitial spaces of the packing materials.
The feed suspension travels into the filtering medium. In the course of migrating through the filtering medium, the suspended particles are trapped inside the pores by virtue of impingement. Because of the limited capacity of the packed bed, multi - bed filtration is suited only for clarifying liquids or gases that contain very small amounts of suspended particles, typically less than 1% on the scale of total suspended solids.
The multi - bed mechanism is observed in municipal drinking water systems and various cartridge filters used in liquid clarification application. Because the content of the suspended particles is sufficiently low, the accumulation of particles inside the filter medium is not significant and multi - bed filtration is treated approximately as a steady state. Its design and equipment operation are relatively simple.
