In practice, instead of 'manganising' sand, it is advisable to use a filtering medium made up of MnO 2 ("green manganised sand", "polarite ".) that can be mixed in greater or lesser amounts with the sand and which will also require regeneration at regular intervals.. oxidation using chlorine. Chlorine does not provide better oxidation of manganese than oxygen at a pH < ; however ...

Definition. Greensand is the name commonly applied to a sandy rock or sediment containing a high percentage of the mineral glauconite. Glauconite ((K,Na)(Fe 3+, Al,Mg) 2 (Si, Al) 4 O 10 (OH) 2) is a greenishblack to bluegreen mineral which forms in shallow marine sedimentary deposits.. Early in the 1900's, glauconite was recognized as having chemical exchange properties in water solutions ...

Glauconite is a mineral commonly referred to as green sand and is used in greensand filtration. It is an effective filtration medium for the removal of dissolved iron, hydrogen sulphide, and manganese from water. Glauconite is coated with manganese oxide, which causes soluble iron, manganese and hydrogen sulfide gas to bond with oxygen.
