Looking At Ways to Filter Water

Households looking to enjoy safety drinking water can rely on a variety of ways to filter water to get them the water quality that they deserve. Throughout the water treatment pipeline and even at home, various ways to filter water can be employed to separate the particulate and biological contaminants from the water stream. Being familiar with these various filtration methods can help one be more at peace with the quality of drinking water that arrives in their homes either via the faucet, delivered by a water vendor, or taken from an external source and requiring extra purification methods to make it suitable for use.

The most important consideration for determining the correct way to filter water is the suspected contaminants that can be included in the water stream. In high volume industrial applications like municipal water treatment facilities, the most common filtration method is called reverse osmosis.

Of the many ways to filter water, reverse osmosis is the most preferred because it produces high-quality drinking water at high volumes and with relatively low maintenance cost. Reverse osmosis uses a ceramic filter with very small pores in the order of a few micrometers wide. Water is pumped from the outside into the inner portion of the tube and only the small water molecules manage to penetrate the thick and small openings of the reverse osmosis filter. As a result, all potential contaminants including big microorganisms get entrained in the filter and separate from the water producing one of the best water quality outputs in the world.

In home applications, reverse osmosis filters also find use in satellite water supply chain stores that deliver potable water to homes. At this scale, smaller-sized filters are used producing water enough for a small community without compromising on quality. The development of reverse osmosis as one of the most reliable ways to filter water and has resulted in a significant improvement in the supply of water regardless of where you are in the world.

Other ways to filter water include the use of activated carbon using the phenomenon called adsorption. Activated charcoal is designed so that very small particles of charcoal produce an excessively large surface area that attracts and traps dust and biological contaminants via electrostatic forces. With the aid of a small enough filter hole to prevent the charcoal from going with the water stream, relatively pure water can be produced in low quantities. In a recent episode of Discovery Channel's famous program Man vs Wild, the host Bear Grylls actually filtered standing water using hand-ground charcoal and his shirt to produce water that was potable enough to be drank.

Homes looking to adopt a greener approach to architecture can also look into building a layered sandtrap of natural filtration agents to produce drinking water from rain. Typical designs involve layering gravel, sand, soil, charcoal and many other naturally occurring minerals in order of the biggest to smallest grains. As the rain water trickles down and passes each of the layers, the contaminants are subsequently filtered until high quality drinking water is collected at the bottom. If you have heard of 16-stage filtration systems marketed by commercial brands, it is not much different from this layered approach from various filter media which are stacked on top of each other to screen off various forms of pollutants.

As you can see, there are enumerable ways to filter water, whether in the home or industrial setting. If you are doubtful with the quality of the water delivered to your home or business, consider using these different ways to filter water and put the knowledge into good use by building your own water trap. There is no substitute to having access to clean water and you would be wise to invest in a sustainable water source right in your own backyard.

Our website specializing in providing information for how to produce water in emergency situations but we do like to include other articles such as this one on ways to filter water. In and emergency situation there are many homemade filters that can be made if you know how to do it. However, it is much easier and even safer to buy some emergency filters for the home in case of a disaster.
