Water Cartridges

Explanations to Water Filtration Systems-

There are numbers different methods of filtering water; each filter has varying degrees of effectiveness, and varying costs. The general purpose of filtering water is to improve the water’s hygiene, taste and aesthetic qualities.

The different types filtering methods employed in water filters for fridges, water coolers and water dispensers and Bubblers is to produce pure filtered water.

There are many and varied choices depending on the degree of purity you want (and/or reductions in contaminant in the water source). Mostly, the more you pay/investing in your filter the better the end results.

Here we list some of the most comment water filter methods-

For a water cooler with a re fillable bottle on top and a filter inside
The filters inside a water bottle are called bottle filters or BFA (an example of it can be found at Bottle filter ) they typically made to have a four or five stage filter system inside- Two stage Sediment, Carbon&Ceramic as final filter.

Filters for a water cooler connected to the mains supply:

Commonly the filters used for mains connected water coolers POU are water filters called CB, (Carbon Block) or activated carbon, designed to reduce such contaminates as sediments, tastes, smells, pesticides, chlorine and a myriad more.
Activated Carbon Filtration is an established technology that works through absorption of the problematic compounds, primarily to remove taste and odor but these systems will also remove some harmful contaminants. AC is a highly porous material with a very large surface area. Chemical pollutants are attracted to and held by the AC’s surface (it is a bit like bloting paper) These water filters are best suited for the removal of organic compounds.

UV (Ultra Violet) Filters are for water coolers connected to mains supply – UV Filters (see an example of a UV Filter at Aqua Pro UV Filter they are designed for biological unsafe water and are able to kill the majority of bacteria and viruses in the water which passes through them.
However, UV (Ultra Violet) Filters won’t remove chemical pollutants from the water (for these you use CB Carbon Block filters). Also you should note that the treatment is ineffective outside of the treatment area, so water should be used immediately after it is treated.
Another type is the Ceramic water filters;Royal Daltonis one of the most famous brands. These filters are also commonly used for biologically suspect or extremely contaminated water.

To removeFluorideand most other contaminates-
There are the specialized filters (often but not always using a combination of sediment and carbon water filters) see our extensive information on RO Reverses Osmosis filters they combine several technologies to help remove the more complex chemicals"such as Fluoride"found in our water today.

Then there are the Water Ionizers specifically to improve your health, see extensive information at Ion life F.A.Q .

The definitive answer to the problem of fluoride in our drinking water – and the most effective long term solution is undoubtedly the Reverse Osmosis technology, which removes up to 98% of fluoride, with similar rates for all other chemicals and pollutants from your drinking water.

Because Reverse Osmosis is so efficient, it also removes all minerals from the water, which actually causes it to be acidic as it draws carbon dioxide from the air on pouring.

The RO systems work by pressuring water up against a semi-permeable membrane that stops contaminants from passing but allows clean water to get through. Both health-related related contaminates-such as lead and asbestos-as well as many aesthetic contaminates that can affect taste, color and odor of water are reduced or eliminated by an RO system.

Reverse Osmosis systems, produce high-quality water perfect for use in drinking, cooking and making ice cubes. The low mineral content of ROtreated water also makes it ideal for use in horticulture, steam irons, car batteries and humidifiers. Today, more than 70 percent of Australians say they are concerned about the quality of their home water. A reverse osmosis system is an effective means producing gallons/Liters of fresh water at a fraction of the cost of premium-bottled water.

HOW SPECIFICLLY DAS REVERS OSMOSIS WORK?

Osmosis is the natural tendency for water of al lesser concentration containing few dissolvent particles) to pass through a semi-permeable membrane and dilute water of a higher concentration (containing more dissolved particles). Eventually, the fluid concentration on both sides of the membrane is equalized.

Reverse Osmosis, as its name implies, is the reversal to the natural flow of osmosis. By applying pressure to the water solution of higher concentration (the incoming water), the flow of liquid is reversed. Under these conditions, the membrane still rejects the containment, but allows the fresh cleansed water to pass through. The purified water is collected and contaminates are flushed away. The process, originally designed to make see water drinkable for the Navy, removes sodium, as well as lead, arsenic, nitrates, asbestos, and a range of other contaminants from household drinking or bore water.

Questions and Answers about Reverse Osmosis Systems for Home Water Treatment :

Q. Who should consider purchasing reverse osmosis systems?
A. Anyone concerned about the quality of their drinking water-particularly if their home drinking water-particularly if they notice taste or odor problems or are aware of high levels of dissolved minerals in their water supply-should consider an RO system. Additionally, RO systems often are recommended for immune-comprised individuals who could be especially susceptible infection from various waterborne contaminants. The center for Disease Control and Prevention (CDC) recommends reverse osmosis as a method for removal of dangers microorganism cyst called Cryptosporidium. Reverse Osmosis systems, which generally include both an RO membrane and pre-and post-filters, offer a comprehensive means of potentially harmful contaminants in home drinking water.

Q. Beyond reducing health related contaminants, what are some other benefits of installing a reverse osmosis water system? A. There are many benefits to installing a reverse osmosis system beyond greatly reduced concentrations of contaminants. Cleaner, sparkling drinking water is probably the most noticeable. Because there is little to alter the RO-treated waters natural state, the flavor of food can come through without anychemicaltaste. Brewed items such as coffee, tea, or soups may have a richer. more robust flavor, and fruit juices and powdered drinks mixed with RO-treated water may taste better, too. Even ice cubes can take on a crystal clear appearance. Q. Does a Reverse Osmosis system remove biological contaminate?

A. RO systems are capable to removing certain biological chemicals such as Cryptosporidium and Guardia. The pore size of the RO membrane along with the amount of pressure applied to the water will generally determine the rate of reduction of such contaminants. The Water Quality Association (WQA)cautions, however, that while RO membranes are reliable for treatment of a range of health contaminants, design considerations such as tiny leaks or manufacturing imperfections may prevent a unit from offering foolproof protection against biological contaminants for consumer drinking water systems. Therefore, WQA suggests that absolute disinfections (a reduction of contaminants greater than 99.9% be ensured with cyst-rated and certified products and post-disinfections systems such as ultra violet light.

Q. How do I properly maintain my reverse osmosis system? A. The filter of your RO system should be changed periodically. In general, both the pre-and post-filters should be replaced every six month, or at least annually: however, the maintenance schedule may vary due to the local water conditions, the quantity of water being filtered, and the manufacturers recommendations. The reverse osmosis membrane normally lasts between 3 to 5 years. WQA suggests you closely follow the maintenance schedule provided by you water treatment specialist or the manufacturer to ensure that the system is in proper working order.
