Reverse Osmosis Water Purifier Guide:

Reverse Osmosis Water Purifier Guide However, there are a few other facts which provide these under sink water filters a slight edge above the other counter top models. Here is why: 1. Since under sink water filters are installed under the sink, they are completely saved from human boo-boos like hot oil splashes! As a result, these systems generally involve less maintenance cost and prove to be more durable too. 2. Again, since they are installed under the counter, there is no restriction on the size of the filter you can install. If you have a large family, you can very well choose to go for a filter with a larger capacity. This specifically becomes a problem with counter top ones where increasing the capacity may lead to a space crunch on the counter. 3. These filters are completely hidden and you are saved from the worry of them disturbing your kitchen décor.

Slide 2:

Reverse osmosis sound very expensive for this. There are sand media filters available that use a special sand to take iron out of water. These can be purchased and normally you will have a maintenance contract with a company who will monitor and change the sand as needed. Try a company like Collegian if there is one in your area. If the water is going to be used for non potable (non drinking water) you can install a small injection pump to the supply line after it leaves the well. With this pump, you can inject a measured dose of chlorine or bleach so that it mixes with the water and allows the iron to oxidize so it will not stain. Little Giant makes injection pumps that will work in this application. You will also need to have a large tank for the chlorine solution. Maybe a 20 – 30 gallon tank.

Slide 3:

You might disagree but hear me out on this; water filters based on reverse osmosis membrane technology does not result in 100% pure and healthy water; instead, various studies have proven that the resultant water is de-mineralized and it contains harmful chemicals like THMs ( trihalomethanes ) and VOCs( volatile organic chemicals), which are health hazardous. Let us now understand the primitive functioning of a reverse osmosis membrane filter. These filters consist of RO (reverse osmosis) semi permeable membrane through which water is forced to pass through. The filtered water is collected at the other end of RO layer.

Slide 4:

Under the assumption that all the impurities present in the water have larger molecular size; it is believed that none of these impurities passes through the reverse osmosis membrane; rather, all are retained on this porous layer and the end-water collected is pure and contamination free. However, this is not true. You will be surprised to know that there are around 20 millions types of contaminations known to human kind and amazingly, this number is on increasing trends. We will be fools to assume that all these size of all these impurities is larger than the porous of the RO layer and hence, the resultant water is pure.

Slide 5:

Studies have proven that impurities like chlorine, chloramines, THMs, VOCs, etc. have small molecular size and this is why they pass through the RO layer to become the part of so-called pure and clean water. Obviously, the consumption of this impure water could result in migraines, upset stomach, poor digestion, lack of concentration, mood swings, poor memory, etc. Moreover, the size of minerals (like magnesium, calcium, potassium, etc.) that are present naturally in water are larger than the pores of this semi-permeable layer. This means that while water passes through the layer, these minerals are caught in the pores of the RO layer and the resultant water is mineral free.

Slide 6:

The consumption of de-mineralized results in mineral deficiency in the body and it affects the bones and teeth adversely. Brittle bones, pain in joints, bleeding from gums, and plaque are few common after effects of prolonged consumption of de-mineralized water. Furthermore, the reverse osmosis membrane based purifiers are not efficient. They produce less than a gallon in an hour. Typically, they waste around 2/3rd of the water, which increases the cost of filtered water per gallon to 18 to 24 cents. In conclusion, reverse osmosis membrane water purifiers are not light on pocket, not eco-friendly, and do not result in real clean, pure and healthy water.

Slide 7:

While we have been talking about these two configurations, you will find it surprising that there are still some obsolete purifiers which do not offer this kind of configuration at all! I am talking about the systems which are based on the principle of Reverse Osmosis. They are very hard wired systems – absolutely difficult to be customized. They only come with one configuration i.e. to install them over the faucet. Then again you have to make sure you get them deployed near the drainage pipe unless you want its outlet pipe running all over your kitchen.

Slide 8:

These two basic configurations are something that any good purifier should provide. After all it is the most basic choice that can be offered to the consumer. It is their apartment and their kitchen – so why not let them decide where they want their purification unit to be installed?

Slide 9:

Under sink water filters and counter top models are really a matter of choice. Whatever you choose, make sure it is based on the latest filtration techniques like carbon filtration, sub micron filtration and ion exchange . A combination of these techniques ensures a performance of a high 99% in purifying the water.

Slide 10:

Slow water from our GE refrigerator from water/ice maker.? We have a GE side-by-side refrigerator (only about 3 months old) with water/ice maker. I just changed the source of the water from the “tap” to our Reverse Osmosis system. The water coming out of the refrigerator is painfully slow. I’m concerned that it may not be able to properly make ice cubes. I’ve read something about a “filter bypass plug”. Has anyone ever tracked one of these down? Did it help? If so, where did you find it? I’m going to call GE appliance parts tomorrow. Before going on to the parts, have this first diagnose to an Refrigirator technician. Its the flow of water passing to some tube. Have this check and if its slows on making ice, maybe there’s a leaks on tubes like the prion has leakage. Prions is the one that fastens the making of ice aside from dialing it to no.2 on your adjustment to coldness.
