Manganese Dioxide
For iron and manganese removal from potable water. Generally used in admixture with sand, iron and manganese removal is achieved simultaneously during filtration. |
Filtration Garnet
Used either alone or in multimedia filters in conjunction with sand and anthracite. Allows the removal of fine particulates which may not be retained by sand filters. |
Support Garnet
Used as a support beneath filtration garnet to prevent migration through the support layers and to ensure the stability of the bed. |
Filtration Anthracite
Filtration Sand
The standard filter medium for water treatment. High silica sand is available in several grades for both rapid gravity and slow sand filters. |
Support Gravels
Used beneath the filtration media as a support. Support gravels are available in various grades. |
pH Correction Media
Microcrystalline calcium carbonate and semi-calcined dolomite for pH corrections and re-mineralisation. |
Active Carbon
Coconut shell and coal based carbons for dechlorination, taste and odour removal and organics removal. |
Alkali Resistant Media
A specially produced material which withstands process liquors of pH 12 and above which would dissolve silica sand. |
