What’s Getting Removed from Your Water?

Water filters do an excellent job of removing contaminants from your water, resulting in cleaner, fresher water for drinking and other uses around your house. But what exactly does the filter remove? This mostly depends on the kind of filter you’re using for water purification in Shelby County, OH.

There’s no such thing as a single water filter that will remove every single type of contaminant from the water, but you can combine multiple methods to provide a more all-encompassing treatment process.

The main processes by which filters work are physical filtration and active (or chemical) filtration. Most filters will use a combination of these methods. Here are some examples of the kinds of contaminants that will be removed from the water when combining different types of filters.

Sand, silt and other sediments

The most basic water filters available will, at the very least, get any types of dirt, sand or other sediment out of your water. You can use either cartridge filters or backwashing filters to remove this sediment. While these filters have different designs, they work in the same basic way—water comes into the filter and then flushes through some type of filtering media, such as polyester or filtering sand. The larger particles are not able to pass through the filter, so they remain behind while the cleaner water comes out the other side.

Chemicals and ions

Active or chemical filters remove chemicals and ions that get dissolved inside your water. In these types of filters, the filtering media has been treated in a way that will cause a charge in the contaminants when it’s exposed to them in untreated water. After these contaminants have been charged, the filter is able to keep them in place, removing them from the water which then passes through to the other side. There are many different filter types in this category, including bone char, ion exchange and granular activated carbon.

Chlorine and chloramines

People often wish to remove chlorine from their water. Municipal water treatment systems in America frequently use chlorine and chloramines to kill off bacteria in the drinking water supply. These chemicals are highly effective, but can linger in the water supply, causing it to taste and smell bad and potentially causing skin irritation. Granular activated carbon (GAC) filters are highly effective at removing chlorine, and catalytic carbon filters are best used for removing chloramines.

Fluoride

Fluoride is a type of chemical added into water supplies to reduce tooth decay, but some people choose to remove it from their water. This can be a challenging process, which requires a bone char filter or reverse osmosis system (and often a combination of the two).

Iron and sulfur

Iron and manganese are occasionally found in the drinking water supply, and are best removed with oxidizing filters. When these minerals get oxidized, they solidify and can more easily be filtered out. Sulfur, meanwhile, can have its presence reduced in water through the use of a GAC filter.
