Armcon Ltd have pioneered a Sludge Processing Unit to eliminate the sludge to landfill problem. The uniquely designed mixer unit processes dewatered sludge with powders. This process changes the molecular properties of the material from a plastic state to a non plastic state which quite simply means that it will not revert back to its wet sludge form. This will allow the processed material to be used in a manner of different applications as a valuable aggregate for resale rather than a material which costs to handle or dispose of.
Processed materials can be used
- Blended with 6F2
- Blended with Type 1
- As a road base
- As hardcore
- As pipe bedding
When the sludge material is processed using the ASP-6 , the platelets go through an ion exchange process, causing a change in the way the platelets align, as shown in the pictures below. This gives an increase in material strength and will normally occur quite rapidly – the strength gain can continue for over 10 years.
