Auto-Vac® Sizing Rotary Vacuum Drum Precoat Filter Drum sizes are determined not by how much water is going to the Auto-Vac® filter, but by how fast the volume flows through the Auto-Vac® filter media. The filtration rate is based upon square footage, because the filter (if flattened) is square. The formula is:
Rotary Vacuum Drum Filters are horizontal drums with perforated exteriors covered with a filter cloth and internal vacuum pipes that are designed to be partially submerged in a trough of liquor. The internal vacuum pipes create suction on the outside of the drum.
The NFM Rotary Drum Vacuum Filter is a continuous filter for low-to-medium production rates with medium filterability.It is used typically with medium to low resistance filter cakes. However, the NFM Precoat Discharge Rotary Drum Vacuum Filter uses filter aids such as dicalite or perlite as a precoat for high resistance filter cake conditions.
1.1 ROTARY VACUUM DRUM FILTERS The Rotary Vacuum Drum Filter belongs to the bottom feed group and is one of the oldest filters applied to the chemical process industry. Therefore rotary vacuum drum filters are certainly used in to the best part of solid liquid separation process. The Figure 1, shows the basic
A. Rotary Vacuum Filtration 1. Conventional Rotary vacuum filtration basically consists of a cylindrical drum covered with a filter media which rotates partially submerged in a vat of sludge. The physical mechanisms which take place during vacuum filtration may be divided into three phases (see Figure VI-1).
rotary vacuum precoat filter: 1. The level of the process slurry in the vat. 2. Filter drum, i.e., the time required for a drum revolution. The optimum knife advance rate [per drum revolution] is a given condition determined by the interaction of the process slurry solids and the grade of filter aid being used for the precoat. OPERATING CYCLE
