Maddox ®, Ion Exchange Catalyst, is generally known as a Green Sand. Maddox was developed as more efficient homogeneous granular filter media to extract dissolved salts of iron, arsenic, manganese and alumina found in South African raw waters.

South Africa a country with huge mineralization on various minerals especially Iron presence in the highly ferruginous sails and massive deposits of Iron Ore was a country side problem.

Maddox® became a useful low cost tool to overcome the problem. In many instances as South Africa has a large percentage of the world’s Manganese deposit a combination of both salts was a common problem.
