MULTI-MEDIA
GREENSAND
CARBON 1000 GPM SYSTEM
MANCHESTER Hi-Rate Filters are available in a variety of
materials and configurations. Units are furnished as stand
alone units or multiple units - skid mounted and manifolded
together. Manual and automatic controls and monitoring systems
are available with PLC and graphic interface. Filters are
available complying with ASME Section VII, Division 1, and
code stamped. Internals are available in stainless steel,
PVC or ABS.

APPLICATIONS
MANCHESTER applications include:
Wastewater
Iron and Manganese Removal
Drinking Water
Oil Field Product Water
Organic Removal |

As shown here, Manchester's unique distribution and collection
systems assure optimum flux during service and backwash. Distribution
nozzles are precisely configured to ensure that flow reaches
evenly to the outer edges of the bed.
The collection system is positioned in the vessel so that
it accepts clean effluent and rejects even the smallest media
particles.

Peak Performance
By carefully selecting combinations of media grades and densities
for each application, media migration and replenishment are
reduced. Runtimes of 8 to 24 hours are attained.
Backwashing Effectiveness
A fully automatic backwashing sequence begins when the filter
reaches a programmed differential pressure, typically 25 psi.
Air or gas is evenly bubbled through the bed to agitate all
the media grains. The resulting grain-to-grain scrubbing action
overcomes the adsorption of particulate, oil and gelatinous
material collected on the grain.
Contaminants are removed from the bed with a strong water
flush, and in special applications, backwashing is enhanced
with chemical injection. After backwashing, the permanent
media grains return to their original arrangement of fine
layer over coarse layer in "like new" condition.
