Why Advanced Water Purification Technology is Essential

As everything develops, options increase. Water purification technology is no different. Although the methods of water purification are different, not all of them are created in the same way.

Problems associated with the above methods

One of the oldest active methods of water purification is distillation. Although not very advanced anyway, it sets the standard for water treatment technology. The process is simple. Water is boiled in an airtight container with a tube that leads to another container. Steam condenses on the pipe and drips into a second container. The problem is that everything that has a boiling point above 100 ° C remains indiscriminately, and everything that has a boiling point below 100 ° C is also collected in a second container. This means that healthy minerals are lost and chemicals are preserved.

More efficient water treatment methods are always required, especially desalination-capable designs. Reverse osmosis developed in response to this need. Promoting the same strengths and weaknesses as distillation, he justified his existence by the fact that he needed much less care and human interaction than motionless, and produced much more water. Although it is out of date beyond desalination, you will still find people trying to sell this relic of water purification Tech.

Designed to remove contaminants without changing the amount of minerals, a water treatment technology known as a microporous membrane, mainly a three-part sieve, has been developed. Each part is designed to block infiltrates less than the previous one. Unfortunately, these water purification methods cannot deal with chemicals or bacteria.


Ultrafiltration is an advanced and highly customizable water treatment technology. Membranes are chemically engineered to block infiltrates of certain sizes. The problem is that you want to eliminate all the infiltrates, not just some or one of them. Although conventional water treatment methods are widely used in industry and industry, they are not intended for drinking water.

To eliminate chemicals, a water treatment technology called electrodeionization is available. Unfortunately, that’s all you can do. Any other infiltrate will not affect or reduce the effectiveness of ion exchange based water purification methods. This means that the water to be electrodeionized must first be filtered off from all organic infiltrates.

If sieves and membranes are not your thing, water can be bombarded with ultraviolet radiation. Including nothing more than a large flat tank and a series of low-density mercury lamps, this is a very effective and efficient bactericidal method.

The answer to these problems

Despite all the new and interesting methods of water purification, the most effective water purification technology was developed to counter the chemical war in the First World War. Commonly known as activated carbon filtration, it simply passes water through a filter made from special carbon. Activated carbon blocks almost everything harmful, but leaves useful minerals. A small problem is that any blocked bacteria will remain in the filter.
