Granular
Activated Carbon
It is a hybrid mixture of a wide variety of
graphite platelets that are interconnected by nongraphitic carbon bonding. The
adsorptive capacity of GAC makes it ideal for removing a variety of
contaminants from water, air, liquids and gases. Besides, it reduces a range of
dissolved contaminants such as chlorine, THMs and heavy metals from water. GAC
is also an environmentally responsible product that can be reactivated through
thermal oxidation and used multiple times for the same application.
Mineral
Stone
Primarily, it uses after RO Systems. Mineral
Stone releases easily absorbed, ionized minerals into the water, including
calcium, iron, magnesium, potassium, zinc and other trace minerals. When
removed from its source of alkalinity, the pH of water will decrease. The
purpose of these stones is to maintain the alkalinity of water while adding
trace minerals. They mimic the natural effect of the rocks that line fresh
mountain streams, and generate the same fresh, and great tasting water.
Phosphate
It is used to sequester iron and hardness
to prevent scaling and precipitation reactions in beverage and ice making
equipment when hard water is a problem. In Australia, this technique is
mostly used to encapsulate calcium and
magnesium hardness preventing scale build up in hot water services and heat exchanges. This works by coating the ions at the molecular level preventing the precipitation of these elements. As used in the US, it also has the ability to coat the inside of pipes and connectors preventing corrosion under some specific circumstances it can be very successful.

Calcite
Calcite is a crushed and screened white
marble media which can inexpensively be used to neutralize acidic or low pH
waters to a neutral, less corrosive effluent. One of the advantages of Calcite is its
self-limiting property. When properly applied, it corrects pH only enough to
reach a non-corrosive equilibrium. It does not overcorrect under normal conditions.
It is a naturally occurring calcium carbonate media. Adding calcite to
water gives water alkalinity which offsets the acidity of water caused by dissolved
carbon dioxide. Upon contact with calcite, acidic waters slowly dissolve
the calcium carbonate to raise the pH which reduces potential leaching of
copper, lead and other metals found in typical plumbing systems.
