Filterability Index Apparatus

Specification of  Filter Ability Index Unit

• Equipment
  consists of a metal framework supporting a 1.5 liter vessel connected
  by transparent tubing to a 60mm high filter unit.


• A 0.5m water manometer measures head loss across the filter.


• Test filter cell diameter: 38mm. 

Description of  Filter Ability Index Unit

1. The
   use of deep beds of porous granular media to filter liquids to improve
   their clarity is widespread in municipal and industrial practice.
   Predominant is the filtration of drinking water and industrial water,
   although the filtration of sewage as a tertiary stage of treatment is
   increasing. Other liquids are filtered through granular media in the
   processing of beverages and food products for example.


2. A simple
   measure of whether the liquid is filterable is useful to enable
   assessment of filtration as an appropriate process, if so what type of
   pre-treatment and filter media are required. Although the normal methods
   of chemical and physical analysis such as suspended solids content,
   turbidity, color etc. may, with experience, indicate whether a
   suspension is filterable, they give no direct measure of this property.


3. A
   number of measures of filter ability have been proposed, using woven
   micromesh, lint pads or membrane filters, which have application where
   these materials represent, or are identical to, the filter media to be
   used. However none of them is representative of porous granular filter
   media, such as sand, consequently they are not applicable to deep bed
   filtration.


4. The Filter ability Index Unit utilizes a bed of
   granular material, normally sand, which can be chosen by the
   investigator to suit his own purposes. The measurements taken with this
   apparatus enable a filter ability number to be calculated which has
   significance in deep bed filter performance.


5. The Filter ability
   Index Unit is not intended for filter design purposes. That requires
   pilot filter column equipment such as the Deep Bed Filter Column.
   However preliminary assessment of pre-treatment processes, and possible
   filter media with the Filter ability Index Unit will reduce the amount
   of testing required with pilot filter columns.
