Application

Expanded clay Hydroponics Water treatment: Wastewater---Biofilter, Filtrations

Expanded Clay is successfully used for water filtration and for wastewater purification, often associated with sand in dual media filtration systems.

Because:

it provides a large surface area for filtration.
it provides ideal conditions for development of the biofilm (consisting mainly of bacterial colonies) in which the process of biological purification actually takes place.
its durability. For all practical purposes, expanded clay is an everlasting material that does not rot, does not degrade over time, and resists acids, bases, solvents, and freeze/thaw cycles with no chemical or physical alteration.
it is extremely easy to lay and maintain because of its lightness and its suitability for pumping.
its low and controlled density means that pump filters are easy to clean (by backwashing) thereby enabling pumps of lower power to be used.
