Multi-media Sand Filters
We are Water Treatment Specialists and we have solutions available for problems
Where it is necessary to treat all incoming water (point of entry - POE) in large volume for the removal of grit, sediment, turbidity and organic matter but also where there is a problem with oxidized iron (‘rust’) and other precipitated contaminants such as manganese or scale particles.
Multi-media sand filters normally consist of three media layers (ie. Support base gravel, micro screened sand and anthracite) and are a very economical means of primary filtration to remove the bulk of suspended solids. (They are particularly efficient on surface waters). Multi-media filters are periodically backwashed (either automatically or manually) by simply reversing the flow and this flushes to waste the accumulated sediment and also re-grades the filter media layers.
OPERATION & MAINTENANCE
Is extremely simple. After initial set-up, the system is virtually self sustaining. With the Automatic Head, back-flushing and clearing of trapped contaminants occur automatically, with manual head this is done by hand with lever. Replace media approximately every three years.
