Company Brief

Harsh Geo Chem Private Limited has successfully put up a plant for manufacturing Perlite filteraids in India. The plant is located at Mehsana, dist. North Gujarat. The perlite manufactured by the plant  is branded as CLEARFLOW and is thus a natural aid to industrial filtration.

Perlite in its natural state is a volcanic siliceous rock containing 3-4% of occlude water. When crushed and heated up to a temperature of approx. 950 C, it pops like “popcorn” expanding to about 20 or more times its original volume. This popping action gives rise to a host of properties that make the Expanded Perlite ideal for use in many industrial applications. The expansion process also creates one of perlite’s most distinguishing characteristics: “WHITE COLOUR”.

Chemically, it is an amorphous mineral consisting of fused sodium potassium aluminum silicate. Solubility of CLEAR-FLOW Perlite Filteraid is extremely low in organic and inorganic acids at both high and low temperatures. Solubility in alkalies depends upon the kind of alkalies, the concentration and time & temperature in contact.

  • pH of a 10% suspension is in the range 6.5 to 8.0.

The correct grade of CLEAR-FLOWTM  to be used will depend on The nature of liquid, solid suspended impurities and the. Type of filter equipment used.

  • Particle size -

It is directly related to Filteraid performance. Larger the particles size more permeable is the Filteraid. Proper blend of particle size gives highest clarity at maximum flowrate.

  • Filter cake -density

As compared to the diatomite Filteraid Perlite filteraids form lower density cakes. CLEAR-FLOWTM Filteraid is available in wide range of grades. The Filter equipment to be used is depended on this factor.

  • Body feed – High cake density(230-300 Kg/M3)

  • RVF – Low cake density (150-230 Kg/M3)

  • Clarity -

FILTER-FLOW Filteraids can filter out sub-micron range particles (less than 1.0 micron size). Low permeability grades of CLEAR-FLOWTM give the Highest clarity.


CLEAR-FLOW™ Filteraids are used as:

1.Precoat: The liquid to be Filteraid is allowed to flow through a packed layer of Filteraid.

2.Body feed: Filteraid itself is added to the liquid to be Filteraid.
