Philterkol...the Anthracite ALL-PURPOSE Filtering Medium

PROPERTIES and CHARACTERISTICS of PHILTERKOL

PHILTERKOL, a carefully selected and graded Anthracite, is hydraulically classified to contain a minimum of inherent ash and mineral matter. It is meticulously screened to yield sizes suitable for filter purposes.

PHILTERKOL does not react with either acid or alkaline waters. It is "nature's purest carbon" and contributes no taste, odor, or other impurity to the water passing through it. It is especially adapted to the filtration of hot alkaline solutions because of its neutrality. It is used effectively and without reaction with acid solutions.

  PHILTERKOL SAND and/or GAVEL
Density (Lbs. Per Cu. Ft.) 56 100
Volume of One Ton (Cu. Ft.) 36 20
Shape of Grains Angular Spherical
Toughness Comparable Comparable
Specific Gravity 1.6 2.7
Solubility in Acid Waters None None
Solubility in Alkaline Waters None Forms Silicates

PHILTERKOL particles are irregularly shaped, angular and of different specific gravities. Sand and gravel particles are regularly shaped, almost spherical and of the same specific gravity

With less classification of particles and consequent less packing of media, the entire depth of a PHILTERKOL bed participates in the filtering operation.

For these reasons, longer filter runs and greater flow rates are obtained. Lower back wash velocities and smaller amounts of back wash water are required than with sand. This result in short periods of out-of-service time with the same of better quality of effluent.

PHILTERKOL sizes are comparable with filtration sand and gravel:

PHILTERKOL #4 9/16" x 5/16" 14.29 mm x 7.94 mm
PHILTERKOL #5 13/16" x 9/16" 20.64 mm x 14.29 mm

ADVANTAGES of PHILTERKOL

PHILTERKOL is more economical to use than sand or gravel through its longer life, greater capacities, less backwash and its many other superior properties.

Plant capacities are increased, filter rates are greater and filter runs are longer due to less lime cementation and the ease of its removal when the lime soda softening processes are used. There is less build-up of surface coatings and weaker bonds to the PHILTERKOL particles which allow easier and less backwash for removal than with sand. All encrustations and grease accumulations are held less tenaciously.

The iron and manganese salts when coagulated adhere loosely to the PHILTERKOL particles. On backwash, they are readily released and clean surfaces are prepared for the ensuing run. There is a tendency for discoloration, coating and moss-like growth on sand and particularly for the supporting gravel which is nil with PHILTERKOL.

The effluents of the filtrations with PHILTERKOL show the same of better turbidity and bacterial removal than sand and at greater efficiencies.

In open beds exposed to the elements, such as sewage filters, little trouble is experienced from freezing in frigid atmospheres when PHILTERKOL is used. In actual comparisons, sand filters had to be discontinued due to freezing, whereas PHILTERKOL beds remained in continuous service without difficulty throughout the winter. In addition, no degradation or splitting of particles has been observed. Sewage beds remain more pliable and dewater more readily than sand due to the greater porosity.

Quantities of filter media used are governed by volume. Since it has a lower density and weighs less per cubic foot, PHILTERKOL requires less strength of confining equipment and less support than is required for sand or gravel.

ADVATAGES of PHILTERKOL SUMMARIZED 

1.   Irregular and angular shaped grains.
2.   Nearly twice the volume for a given weight.
3.   Extended filter runs.
4.   Increased filter rates can be maintained with better quality of effluent.
5.   One-half the back wash volume and velocity for 50% expansion of bed.
6.   Lower air pressure where air wash is used.
7.   Media loss is lower.
8.   Insoluble in acid and alkaline waters.
9.   Reduced build-up of encrustations and oil accumulations.
10.  Removes more iron and manganese salts.
11.  Less lime cementation.
12.  Superior freeze stability in outdoor and open beds.
13.  Far less out-of-service time.
14.  Lower maintenance costs.
15.  Less strength of confining equipment.
16.  Improved turbidity and bacterial removal.

Beds constructed completely from PHILTERKOL are preferable to sand and gravel, but results are being obtained by using a combination of PHILTERKOL and sand in Anthracite-sand filters.

PHILTERKOL is shipped in bags, as well as in bulk box cars and open hopper bottom cars.

READING has been marketing PHILTERKOL for over forty years during which time it has been used successfully by hundreds of industrial and municipal plants throughout the world.
