Water Purification Process - Incomplete and Inept

In order to have an effective water purification process you have to use numerous steps in order to ensure protection from a variety of contaminants. Because of this it can often be difficult to explain water purification clearly. I'll do the best that I can to explain it to you right now.

For eons, the water purification process occurred totally naturally. Rain fell and Mother Earth cleansed it; fresh, pure drinking water was ubiquitous. These days it's a lot more difficult.

What you have to understand initially is what, exactly, must be filtered out of the water in order to make it pure. Chemicals leaching into groundwater are the major problem nowadays. A number of these can be inhibited by an activated granular carbon filter and a multi-media block can take care of the rest.

Next, microorganisms like parasites, protozoa, and bacteria have to be dealt with. Refuse of a biological nature and runoff from agriculture is where most of these come from. The most common water purification process for getting rid of these sorts of contaminants is a chlorine disinfection.

I will use the example of public treatment facilities to explain water purification, because I believe this will give a good outline of the entire process. Cleansing water requires many stages and I think this way of describing them will give you the best idea of what I mean.

The standard source of potable water is lakes. These bodies of water are usually dirtied and full of debris like foliage and branches, marine life, and all manner of stuff. Directing water through a massive screen filter gets rid of them.

The next step in the water purification process is called flocculation. What happens here is that chemicals are added to the water in order to clear it up and to disinfect it. Chlorine is one of the chemicals commonly used in this process. The water is then run through filter units.

It's best to explain water purification at this stage by describing water flowing through a series of strainers, each one of which has a tighter grid than the one before it. In brief, that's what occurs here. With high pressure the water is channeled through a specifically designed variety of filters that are increasingly less porous.

The water purification process at the treatment facilities is not as effective as one might expect it to be. The filters that they use only remove particle debris from the water and they rely on chlorination to do the rest. I don't feel that I can explain water purification without telling you that this is not enough to make our water safe.

Chlorine does not affect the bacteria and chemicals that get through the filter screens. Without additional methods of filtration, our water is just not reliably safe enough for us to drink. Where does that leave us? Well, the following step in the water purification process is up to you.
