Water Filter Media for Water Filter Purification from Industrial Water Equipment Ltd

MANGANESE DIOXIDE
TYPICAL USES, IRON REMOVAL AND MANGANESE REMOVAL.
APPLICATIONS, POTABLE WATER SYSTEMS

Advantages

Iron removal over wide ph range
Effective removal of hydrogen sulfide in addition to iron and/or manganese.
No harmful effects from a chlorine feed.
Low attrition loss for long bed life

MANGANESE DIOXIDE is a naturally occurring MANGANESE ore that is selected for its capacity to attract heavy metals, such as IRON and MANGANESE, and for the co-precipitation of ARSENIC. The media will remove other contaminants such as HYDROGEN SULFIDES ETC.

Physical Properties
Color - Black
Density - 85 lbs./cu. ft.
Effective Size - 0.30 - 0.35 mm
Uniformity Coefficient - 1.6
Mesh Size - 16 - 60
Attrition Loss Per Year - 2%

MANGANESE DIOXIDE will not affect alkalinity, or the pH, of the filtered water, and does not add any extraneous species during treatment.

MANGANESE DIOXIDE IS Sometimes referred to as pyrolucite, MANGANESE DIOXIDE can operate at flux rates up to 15 gpm / ft. sq., depending on the raw water quality / contaminant levels. Contaminants in the raw water (ARSENIC, IRON, MANGANESE, HYDROGEN SULFIDE, organic carbons, etc.) are first oxidized (usually with CHLORINE ADDED WITH A DOSING PUMP AT A SET RATE ) and are then adsorbed onto the filter media. MANGANESE DIOXIDE is a permanent media that is backwashed with filtered water, and does not require chemical regeneration. Backwash water can be collected, and the sludge settled, resulting in a reclaim rate of approximately 99%. MANGANESE DIOXIDE can be used for potable water and bottling water, brewery and soft drink manufacturing, in pressure and gravity filters.
