Our can offer mobile plant to stabilise sludges using limes. This treatment is usually applied to liquid sewage sludge but can be deployed to stabilise other sludges.
Principal chemical treatment processes include adding quicklime or hydrated lime. Hydrated lime will raise pH, whereas quicklime will give a rise in pH and temperature. This temperature rise to 70 degrees C pasteurises the sludge, reducing pathogens such as salmonella and e.coli and reducing unpleasant odours. The remaining product can be used as an effective organic fertiliser or soil ameliorant.
