BASF's patented category defining adsorbent ATS Powder remains the gold standard for dissolved lead and mercury removals in carbon block applications - molded or extruded. ATS is a high capacity ceramic ion-exchanger with great kinetics due to its formation, and is selective for lead removal even in the presence of competing ions like Calcium and Magnesium. With our product, the captured Lead is not displaced by hardness ions commonly found in tap water. It is the lead reduction technology in more NSF 53 Lead reduction certified blocks than any other technology.

BASF's, formerly Engelhard's, ATS will not leach organic or inorganic residues like Aluminum like some other technologies and strong matrix will process well in block applications without crumbling. The material is available in two partical sizes; 20-35 microns for typical blocks, and finer 8-12 microns for tighter blocks such as those making cyst reductions claims.

ATS has ANSI/NSF Standard 61 certification for drinking water systems - health effects, and complies with US FDA regulations for food and water contact.
