Laterlite is an excellent medium for various types of filtration and purification system:
WATER FILTRATION MEDIA
Laterlite Expanded Clay is successfully used for water filtration in potabilisation plants and for wastewater purification, often associated with sand in dual media filtration systems.
Some of the main advantages are:
ODOUR CONTROL MEDIA
Laterlite Expanded Clay is an excellent granular medium for use in biofilters, bioscrubbers, and packed towers (air biofiltration) that eliminate the airborne odours emitted by wastewater treatment plants, sewage treatment plants, industrial processes, and effluents.
Because of its dense network of cavities and its ability to retain moisture, Laterlite Expanded Clay is in fact the ideal support for the growth of the microorganisms that reduce biological odours.
Because of its resistance to crushing and to acids, bases, solvents, microorganisms, insects, and freeze/thaw cycles, the excellent durability of Laterlite Expanded Clay far exceeds that of alternative odour control systems based on organic materials such as wood chip, shells, or peat/heather.
