METALOK^®

Heavy metals are amongst the major pollutants in the environment.  Metals occur as pollutants in industrial and domestic waste waters, solid wastes and also pose a major problem with recycling organic waste into compost. They are not degradable and thus can build up in both solid and liquid wastes, and in receiving soils. METALOK is a unique product specially developed to manage heavy metal pollution in soils, and solid and liquid waste. METALOK is a specially formulated integrated mineral compound that is very effective in reducing heavy metal contamination in soils and water. METALOK is designed to manage heavy metal pollution effectively in a range of environmental conditions by the integration of several active metal immobilisation mechanisms:

·      Precipitation ·      Chemisorption ·      Adsorption ·      Chelation ·      Co-precipitation

These mechanisms provide METALOK with the flexibility and power to effectively deal with metal pollution in most situations. METALOK Performance  

METALOK has a very high metal absorption capacity as shown in the table and figure below.

METALOK can be applied to:  

·         Contaminated soils to achieve TCLP test compliance
·         Composting of organic wastes, such biosolids or municipal waste, to reduce metal concentration and mobility
·         Treatment of metal containing waste waters such as metal plating, photolabs, etc.
