DESCRIPTION OF THE SCHNEIDER HORIZONTAL PLATE FILTER
The Schneider filter is a horizontal plate type pressure filter. The filter plates are stacked horizontally one on top of the other to create the filtering area. Plates are stacked up to twenty high, which permits 230 sq. ft. of filtering area in a single stack. By adding additional stacks (up to a total of five) it is possible to attain a filtering area of 1150 sq. ft.

FILTER OPERATION
Each filter consists of the filter plate stack (or stacks) which is opened and closed during cleaning cycles by a mechanically operated jactuator.

When maximum operating pressure is reached, the filter is cycled. The sequence is as follows:

The inlet flow to the filter is shut off, and the filter stack(s) are drained of all internal liquid. Compressed air then dries the filter cake. The filter plates separate and the spent filter cake and media are extracted from the filter stack(s) by means of a media extractor located at the end of the filter. Since the filter media is stored on rolls, new media enters each of the filter plates as the spent media is extracted.

The jactuator then closes and seals the filter plates. The automatic valving permits precoating of the media and the filter goes "on stream". The entire cycle time is between 10 and 20 minutes.

To prevent capillary leaking around the filter plates, a vacuum is drawn around the entire periphery of the filter plates.

PRECOAT BODYFEED SYSTEM
Because of the fineness of the filter media, precoating is quickly completed. This eliminates the need of a seperate precoat system.

THE FILTER PLATE
The filter plate is designed to operate with or without filter aids. The filter cake builds on each of the filter plates in a horizontal plane, thus eliminating the loss of the filter cake in the event of a power or pump failure.

THE FILTER MEDIA
Because the Schneider filter uses a disposable media on which the cake is formed, each time the filter is put through a cleaning cycle the user is assured of starting with a new filter media.

Since the filter operates to high pressures (up to 60 psi), a wide variety of filter media may be used for various applications such as diatomaceous earth cake or paper media without diatomaceous earth.
