General
Our AF Series Filters are fully automatic incorporating Backwash, Rinse-Pause, Fast Rinse
and Service Cycles, controlled by cam switches in the timer. Frequency of Backwashing can
be altered from that suggested in the Commissioning Section, if actual site conditions
dictate alterations.
Water enters the unit through the multi-port valve and passes through the media,
underdrain gravel and the distributor leaving through the multi-port valve.
Multi-Media Filters
Remove filterable turbidity at high flow rates several times the flow rate of conventional
filters, producing clear filtered water down to 10 micron through the stratified bed without
chemical flocculation. No additional pumping is necessary for Backwashing, as the
Backwash water required is normally only 80-90% of the service flow rate. Multi Media Filter
capacity is many times that of conventional filtration due to utilisation of the entire stratified
bed, resulting in low operating costs.
This unit is not designed to remove colloidal matter, a plant capable of coagulation is
required in such cases.
