Caolim


The addition of alkaline earth metals (quicklime) in sludge-like stabilization sanitation method is aplied internationally since the early 80’s, with use of lime-mixed sludge in agriculture as fertilizer product.

The CaO Hellas produces specialized product CAOLIM, which is produced with controlled exotherm reaction and sanitates and pasteurizes the sludge, creating an alkaline environment with pH> 12 and temperatures above 70 ° C. Also, with amounts of 25 wt% on the dehydrated sludge, increasing significantly the dryness of the material at levels of about 50 -60%, thus greatly facilitating the manageability of the material and its mechanical characteristics.

Features of CAOLIM

• Drying and pasteurization of sludge.
• Reduce unpleasant odors.
• Mitigation of heavy metals.
• Neutralize acids. Water softening.
• Neutralize bacteria, parasites, pathogenic microorganisms.
