Horizontal Plate Filters
Standard Horizontal Plate Filter
Standard Horizontal Plate Filters (SHPF)
The HPF is one the most universally accepted filtration solutions. With the HPF, Sparkler® created a filter that provides uniform flow, no moving parts and simplicity of design. Gravity is the key principle at work. The plates in this model function horizontally and through the topside only, they offer unparalleled stability, versatility, granularity, sanitation, fault tolerance, and efficiency.
Flowing with gravity, liquids compress and secure any medium through which they pass. If pore number and size restrict passage, the intended case with filtration, flow will distribute itself uniformly across a horizontal surface, leading to a uniform functioning of any medium.
Designed for unilateral top flow filtration, the bottom side of horizontal plates offers the most robust support possible for topside media. This in turn enables using the broadest possible array of media, individually and combined, to remove suspended particulate ranging in size from coarse to fine; 100+ microns to <1 micron. Finally, this media diversity permits the use of filter aids of every variety for precoat and bodyfeed.
Within the limits of a given vessel size, plates may be added or subtracted to optimize efficiency.
Since the entire filtration process occurs within a pressure vessel, exposure to airborne contaminants is eliminated, guaranteeing a sanitary condition.
Again, because horizontal plate filtration works with gravity, planned and/or accidental interruptions have no effect on the filtration process or result.
This design may incorporate a scavenger plate. Offline during a productive run, it may be switched online at the end of a cycle to filter 90% of residual liquid. Over hundreds and thousands of cycles such “scavenged” filtrate represents increased efficiency and cost savings by orders of magnitude.
The HPF functionality is based on manual operation. Once optimum throughput is achieved, the filter’s cartridge must be lifted by hand or crane from the tank, disassembled, washed off, reassembled, and inserted back into the vessel before a new cycle can begin. Efficiency can be increased dramatically through the purchase of secondary cartridge that can be swapped with the primary cartridge immediately. Alternatively a spare bottom assembly, consisting of a secondary base ring and scavenger plate may be purchased, enabling an immediate assembly of a clean cartridge as each plate is removed and cleaned. The key here is to handle the plates once, as you take apart and remove cake from one bundle, you begin the assembly of the next plate bundle simultaneously.
