We performed a filter change service call on a reverse osmosis system this afternoon. The "before" and "after" images really show the difference between filtered water and plain old city water. It never ceases to amaze me how the government says the water supplied through the municipal system is clean and safe, "some of the best in the world" I keep hearing…
The image shown here shows what the filtration equipment does. During the maintenance, I changed all the filter cartridges, the "pre" filter, a "post" filter and did some other service. The "pre" filter is exposed to water coming directly from the city of Edmonton. If the water is so good, what is all the gunk all over the filter? The "post" filter is also shown – it was installed at the same time as the "pre" filter, the only difference is that the "post" filter only has water that has been treated by reverse osmosis running over and through it.
The difference? As you can see, other than the fact it is wet and showing a little bit of the carbon block filter it is wrapped around (think of a wet, clingy t-shirt, and how it can become translucent) it is clearly still in like-new, "white" condition. A brand new, still in the wrapper filter cartridge is shown in the middle for reference.
My question is simple – if the water quality in Edmonton, Sherwood Park, St. Albert and the entire Greater Edmonton Area is so good, why do the filters turn this horrible colour after being exposed to our pristine water supply?
Treatment is quick, efficient and easy to use, requires very little maintenance and gives peace of mind – we get rid of the gunk!
