Other Concerns for the Use of GAC

BACTERIA

The major problem associated with carbon in any form is bacterial contamination. Wet activated carbon, richly infused with trapped organic matter, provides an ideal breeding ground for bacteria. High bacterial levels are most likely when the carbon is fully saturated and then left to stand for periods of time in between uses. As the water temperature inside the carbon cartridge rises, so does the amount of bacteria. Silver impregnated GAC has a better chance of reducing the amount of bacterial regrowth that occurs but caution must be used, as even the silver can be overcome by the rate of growth of the bacteria.

Electricity is not usually needed, unless the mains pressure is particularly low. Then a special booster pump is required and a power supply.

The system has an 'auto shut valve', this is a pressure activated control valve that ensures the plant is automatically shut off when the reservoir is full.

Optional 'flush valve’. This is periodically opened

to flush away any accumulated deposits and debris from the membrane. The only running costs arise from the replacement of the two filters every six months.

The reverse osmosis membrane will last approximately 4/6 years (more frequently if the feed water is of exceptionally poor quality, possibly less frequently if a water softener has been installed).
