Installation
& Start Up
- J-Series adsorbers are shipped empty along
with the required carbon. The adsorber should be
connected and all fittings pressure tested for leaks
before the carbon is installed through the top access
hole. After the carbon has been loaded, the unit
should be filled with clean water through the bottom
collector, and allowed to degas for 8-12 hours if
possible. Backwashing the carbon is recommended
to remove carbon fines that can cause excessive
pressure drop through the unit. Multiple units are
usually connected in series with testing between
the units advised to determine when the first unit
needs to be changed out.

Maintenance
- The only
maintenance J-Series adsorbers requires is
the testing of effluent quality, and checking the
operating pressure of the system. Monitoring the
contaminant level into the last unit in a series
arrangement is the recommended safeguard against
having breakthrough in the final outflow. When the
concentration of contaminants in the flow coming
out of the lead unit equals the concentration of
the flow into the unit, the unit has reached its
removal capacity and needs to be serviced. The working
life of carbon is dependent upon the type of contaminant
in the water as well as its concentration and the
liquid flow rate. A pressure relief device is advised
to prevent damage to the system in the event of
excessive pressure buildup. Backwashing an adsorber
that is operating at an elevated pressure will sometimes
provide a temporary lowering of the pressure drop
through the unit.

Servicing
J-Tanks -
Once an adsorber's carbon is saturated by contaminants,
the unit should be taken off line and fresh carbon
installed. To purchase replacement carbon or to
arrange for a carbon change out, please contact
our office. When preparing the unit for servicing,
as much water as possible should be drained from
the vessel.
|
| |
Disposal
- If you change the carbon out yourself, please
dispose of the spent carbon in accordance with Federal,
State and Local regulations.

| Available
Options - Custom features are available for
special needs. ASME Section VIII Code Stamp, Stainless
Steel tanks and/or internals, food grade or severe
service coatings inside or out, custom sizes for
space limitations and different connection locations
for hookup to existing plumbing are routine requests.
Please call us with your needs. |

Warning!
|
|
Wet activated carbon readily absorbs free oxygen. ANY
entry into carbon vessels requires procedures
for confined space entry and oxygen depletion
to be followed!

J-Series
Liquid
Phase Adsorbers are ideal for liquid treatment
applications where higher pressures must be dealt
with. All J-Series units are built to 100
psi standards and are designed for long term installation.
Units have two part Epoxy coatings on the inside
and industrial enamel on the outside. Standard units
have PVC internals, two access ports, a vent connection
in the top and steel FPT fittings and legs. Easy
access to the carbon allows for on site carbon service
and the economy of bulk carbon usage. GC 8x30
or GC 12x40 coal base carbon is standard
with reactivated GC 8x30R and other specialty
carbons available upon request.
