ACTIVATED CARBON
Granular Activated Carbon
may be used for a variety of
water treatment applications
requiring the reduction of
chlorine, tastes, and odours.
Refillable Carbon Cartidges

Traditionally, activated carbon cartridges with capacity to treat all the
in-coming water to a home have been too expensive for many people
to consider, despite their aversion to unpalatable or dangerously
contaminated water.
To overcome this, we have sourced refillable cartridges to dramatically
reduce the operating costs. Being refillable, they are not adding to the
waste disposal and landfill problem
Easily opened to remove the spent carbon, the cartridge can be rinsed,
refilled with new carbon media, and then replaced into the housing –
quickly and easily.
Available in a range of sizes and extremely economical to maintain,
these refillable carbon cartridges are very popular with many people.
We supply the carbon media in 4 Litre containers at whatever intervals
you request to ensure a continuous supply of clean, fresh water with
no objectionable taste or odour characteristics.
Problem

Where the incoming water is
chlorinated, or
where there is the
possibility of
agricultural
chemical spray
drift, or an
unacceptable
“organic” smell of
rotting vegetation
in a rain water or
surface water
supply, we have
an extremely
effective solution
to the problem.
Solution

We now import a
range of cartridges
that are filled with
Activated Carbon
and are specifically
designed to
dramatically
reduce any
unpleasant,
taste/odour and
dissolved organic
chemicals from
water.
Installation
1190/1190FP In-Out Head



The 1190FP 1” In-Out Head is
designed for high water flow.
Water upflow prevents channeling
and allows greater water to media
exposure.
The Head includes a removable
upper distributor basket providing
access to the top of the riser pipe,
allowing water to be drained from
the tank when replacing media.
The 1190FP includes a utility
wrench to be used with the
removable cap.
Granular Activated Carbon


Granular activated carbon is designed for
reduction of tastes, odours, and dissolved
organic chemicals from municipal and
industrial water supplies. Manufactured
from select grades of bituminous coal to
produce a high density, durable granular
product capable of withstanding the
abrasion and dynamics associated with
repeated hydraulic transport, backwashing
and mechanical handling. Activation is
carefully controlled to produce
exceptionally high internal surface area
with optimum pore size for the absorption
of a broad range of high and low
molecular weight organic contaminants.
One of the most common applications for
Granular Activated Carbon (GAC) is the
reduction of the undesirable tastes and
odours present in many chlorinated water
supplies. GAC has been successful for
many years in the reduction of free
chlorine from water supplies. The end
product is clean, fresh water with no
objectionable taste or odour
characteristics


To obtain maximum efficiency of
the activated carbon in the
absorption process, it is
desirable to have the greatest
possible surface area in the
smallest practical volume. This
is necessary because the rate of
absorption is proportional to the
amount of surface area of the
absorbing medium media. GAC
has a surface area of 850 sq mt
per gram. This results in high
efficiency and greater system
economy.
GAC has an extremely high
capacity but must be replaced
when the filter bed loses the
capacity for reduction of taste
and odour. GAC may be used in
either domestic or industrial
applications using gravity flow or
pressurized filter vessels.
Advantages

GAC is an outstanding material for
applications requiring tastes, odour
and dissolved organic chemical
removal from water with suspended
matter present. This product can be
used for filtering waters having a
wide range of pH levels.
Large surface area results in an
exceptionally high capacity and
efficiency.
Balanced pore structure gives a
more efficient absorption range.
GAC is very durable so losses due to
attrition are kept to a minimum.
GAC has a very high-carbon low ash
content.
Service rates of 5gpm/sq.ft. are
practical for ordinary taste, odour
and chlorine loads.
GAC will impart a high ‘polish’ to the
filtered water
Conditions

Water to be filtered should
preferably be free of oil and
suspended matter.
The water to be filtered should be
relatively free of iron and
turbidity for maximum service
life.
Water pH range: wide range.
Bed Depth: 26-30 in.
Freeboard: 50% of bed depth
(min)
Service flow rate: 5 gpm/sq.ft.
Backwash flow rate: 10-12
gpm/sq.ft.
Backwash bed expansion: 3040% of bed depth.
Upon installation, backwash to
remove carbon fines before
placing unit into service.

Client Comments:
‘Dear Sue, As you know, I was concerned about moving into town where all the water is heavily
chlorinated. The carbon tank outside removes the smell and taste from all the water coming inside & I am
delighted with it. I will water my vegetables with the good water as well. The ceramic filter under the sink
takes out even more chemicals and all bacteria – it will be nice not to have to boil water, if the chlorine
dosing plant ever breaks down. Do call in if you are in the area’. TM
