ABSORBENTS

Perlite is a natural inorganic sorbent capable of adsorbing from 4 to 20 times its own weight in hydrocarbons such as oil, petrol and diesel. Inorganic sorbents, like organic sorbents, are inexpensive and readily available in large quantities. These types of sorbents are not used on the water’s surface.

Packaging:
This lightweight mineral can be easily packaged according to the customers’ requirements. We supply socks, booms and pillows in a very strong yet robust cover that allows for spill containment around manhole covers and drains, where leakage into the water table cannot be accepted.


Rate of absorption:
The absorption of oil is faster with lighter oil products. Once absorbed the oil cannot be re-released. Effective with light hydrocarbons (e.g., gasoline, diesel fuel, benzene). Thicker oils adhere to the surface of the adsorbent more effectively.


Oil retention:
The weight of recovered oil can cause a sorbent structure to sag and deform, and when it is lifted out of the water, it can release oil that is trapped in its pores. Lighter, less viscous oil is lost through the pores more easily than are heavier, more viscous oils during recovery of adsorbent materials causing secondary contamination.


Ease of application:
Sorbents may be applied to spills manually or mechanically, using blowers or fans. Many natural organic sorbents that exist as loose materials, such as clay and vermiculite, are dusty, difficult to apply in windy conditions, and potentially hazardous if inhaled.
