The conclusion of a study titled: Industrial Sludge Solidification by Using Clinoptilolite Zeolite, done by the Institute of Environmental Sciences in Turkey reinforced the use of Zeolite to consolidate industrial style sludge using Zeolite. The study was based on three parts: preparation of materials to be solidified, unconfined compressive strength values of the solidified material (UCS), and leaching characteristics using a standard Toxicity Characteristic Leaching Procedure (TCLP). The summary stated that hazardous components in industrial sludge was successfully locked and immobilized in the structure formed by the solidification. For the same reasons that Zeolite is commonly used a pozzolan, high UCS values obtained measured 4448 kPa. Leaching test results were compared to limits given by the Hazardous Waste Control Regulation, it was observed that there is not any leaching problem and the solidified products can be land filled safely (Balkan) & Kocasoy, 2004).
The study concluded that solidified sludge samples were safe to dispose of in landfills, although the potential to be used as a beneficial product such as a concrete pozzolan does exist, which would convert waste into a product with benefits and value.
Each mesh size of Zeolite allows for different characteristics to be taken advantage of. Smaller sizes such as 14-40 sand yielded a 60% – 70% sludge addition, but a lower UCS value. Larger Zeolite size of 7-14 or +7 yielded a lower percentage of sludge absorption, but a higher compressive strength.
Tests done on retention ponds routinely find levels of 200 pCi (Donovan). Zeolite will trap those NORMs in place and prevent leachage.
