Carbon Filter
Many people use the carbon filter to purify drinking water in homes, institutions, and companies, to ensure the quality of the water and its suitability for drinking. The presence of pollutants, and the increase in the percentage of chlorine in the water, all affect the quality and taste of water. It also affects human health, and the expected benefits of drinking water, which is the basis of life. Carbon filters are also used as a pre-treatment process for reverse osmosis water, and as specialized filters designed to remove chlorine-resistant cysts, such as Giardia and Cryptosporidium.
Therefore, many people are keen to choose the appropriate and reliable water filter, and the types of water filters vary in their prices according to the degree of their quality, and the number and type of candles inside the filter.
Definition of carbon filter
A carbon filter is a device for filtering water from pollutants and impurities. A carbon filter, also known as carbon filtration, uses a piece of activated carbon designed to filter out as much of the pollutants as possible in the water.
Carbon media can be made from many materials such as coconut shells, bamboo, fruit peels, and charcoal most famously. When processed through the “activation” process, the carbon media will open a large number of pores that enable the carbon to capture contaminants, which is known as “adsorption / attraction / adsorption”. Activated carbon adsorption function is widely used in residential, commercial and industrial water purification process.
What is active carbon
Activated carbon, or activated charcoal, is a porous charcoal with a very high surface area, and has a great ability to chemically absorb gases and toxins around it. Therefore, it is multi-use, especially in the purification of polluted water and wastewater for drinking, agriculture and industrial use. It is also used to kill bacteria and remove bad odors from the air.
Carbon filter properties
A carbon filter is most effective at removing chlorine, sediment, and volatile organic compounds (VOCs) from water. However, it is not effective in removing dissolved minerals, salts, and inorganic compounds. Typical particle sizes that can be removed by carbon filters range from 0.5 to 50 µm.
The efficiency of the carbon filter also depends on the flow rate of the water. The slow flow of water makes the carbon filter better able to absorb pollutants of the right size.
Types of carbon filter
The most important types of carbon filters used in the filtration industry: bulk powder filters, and activated granular filters. Many carbon filters also use secondary media, such as silver or KDF-55, to prevent bacteria from growing inside the filter.
Does using a carbon filter harm mineral salts?
Dr. Helmy Al-Zanfali, Professor of Water Pollution at the National Research Center in Egypt, answers, saying: “The cost of separating mineral salts from water is very high, and it needs advanced devices that cannot be placed in a small filter of such types,” adding that the water problems are different and multiple, Including the high percentage of chlorine and impurities, and the increase in water salinity, so it is necessary to determine the main problem in the water before purchasing the filter, and to choose the type of filter based on it.
Tips when using water filters
Buy filters from a trusted source and make sure of the brand.
– Ensure the availability of spare parts and original spark plugs.
– Do periodic maintenance on the device by the manufacturer.
Purchasing a salt meter to test the quality of water and the percentage of salts it contains.
– Change the candle of the device when you feel a different smell or taste, even if the specified period has not passed yet.
– Clean the filter periodically according to the manufacturer’s recommendations.
