AMT Systems chosen method of media transfer
depends on actual site operational parameters but the preferred method of installation/charging is hydraulic conveying.
This method causes minimum degradation to friable media (in contrast to pneumatic blowing systems) and there is no limit to the distance over which media can be transferred.
An additional substantial derived benefit is that media is pressure washed prior to eduction into the filter thereby potentially reducing costly backwashing and flushing through time.
Fines can be extracted from the filter together with conveying water which can either be re-circulated to
reduce primary water requirements or passed back through the works for fines separation and re-use or disposal.
AMT Systems method of operation is ideally suited to applications exhibiting restricted access, i.e. rapid gravity or pressure filters situated within a roofed building, but can be even more cost effective than using traditional craneage methods on outdoor, open top, easily accessible filters.
Hydraulic deceleration zones are established prior to commencement of media transfer to protect nozzles/laterals and, as necessary, prior to installation of all subsequent filter layers thereby ensuring total
protection of the filter fabric and clean support/media interfaces.
Pattern/distribution tests are undertaken after
installation of base gravel to confirm nozzle/lateral
integrity.
All AMT Systems personnel are trained in working with the relevant plant and equipment.
We also have our own first aid trained personnel.
