Understanding Water Filters


Water Filter Options:


Water softening: Process used is ION Exchange and replaces hardness (calcium & magnesium) with sodium and potassium. Exchange process eliminates scaling but does not remove dissolved solid totals from water.

Sediment filtration: It is used to remove suspended solids like dirt, rust, cysts and other non-dissolved solids.

Carbon Filtration: Will remove organic tastes and odors. Can be used to absorb other contaminants and chemicals like chlorine, chloramines, volatile organic compounds.

Reverse Osmosis: Process used to remove dissolved solids and commonly used in bottled water processing. Membranes are used to separate water from solids in the water.

Deionization: Just like the water softening ion exchange process. It is two steps that effectively remove all minerals from water. Commonly used in manufacturing of computer components and pharmaceuticals.

Ultra Filtration: This is a method of cross flow filtration ( similar to reverse osmosis, but uses lower pressure) and it uses a membrane to separate small colloids and large molecules from water and other liquids. Like reverse osmosis, membranes are used to separate from water to solids. The process falls between reverse osmosis and microfiltration in terms of the size of particles removed.

This should provide a better understanding to your in house water needs. Personally, this is a much needed option for cafes and coffee shops.
