What are the different types of water filtration?

There are several types of water filtration designed to remove different contaminants. Different methods are able to remove different sets of dirt, but no filter type can remove all possible contaminants. Therefore, it is important to know which substances are present before selecting the filter system. Iron and manganese, on the levels that usually occur in the well, are not health risks, but too much can into the water and coloring of washing, bathtub and descent. Nitrogen and hydrogen sulphide occasionally occur in water. Sulfine causes odor similar to rotten eggs, while too many nitrates can cause methemoglobinemia , commonly called blue child diseases. Water filtration is usually not used for bacterial contamination as groundwater generally has very low concentrations of bacteria. GAC is processed to provide it with a high surface area, causing it to have high absorption. It can capture different particles of contaminants, including iron, manganese, hydrogen sulphide and chlorine. NevThe GAC is that it must be regularly exchanged.

Greensand manganese Greensand is used to remove iron and manganese from water. Glaukonite, active material in the manganese Greensand medium, reacts with soluble iron and manganese to form insoluble versions of these substances that are captured in the filter material. Greensand manganese operates at high iron and manganese concentrations and completely removes contaminants. Regular maintenance is generally required for the filter to work properly.

BIRM is another filter material that is mainly used to remove iron and manganese. It catalyzes the reaction between iron or manganese and oxygen. The oxidation process consists of insoluble iron and manganese, which is then captured by the filter. This type of water filtration also requires regular maintenance to clean the filter material.

Aniont exchange and ion exchange, also known as water softening are two similar methods of treatment that work to remove different contaminants. Both methods remove particles of contaminating substances when the water passes through a charged resin bed. The ion exchange uses a negatively charged material to capture positively charged ions, including iron, manganese, calcium and magnesium, while the anion exchange uses a positive resin to capture negatively charged ions including nitrate, sulphate and fluoride. Both types of treatment can cause corrosive water and increase the sodium content.

Reverse osmosis (RO) is a method of filtration using a selective membrane. The pressure is used to enforce water through this thin material and leaves the contaminants on one side while the cleaner water passes. RO can remove a wide range of contaminants, including iron, manganese, nitrate, sulphate, sodium, fluoride, chloride, heavy metals and some organic materials. On the other hand, reverse osmosis is often not for household adjustment systems because RO unitsThey are expensive and require a large amount of water.
