What are The Unique Features of Carbon Filters in Water Purifiers? How Do They Help in Providing Clean Water?
In the course of filtering water, carbon is a media that is frequently utilised. In reality, carbon filtering is used in some capacity in almost all types of water filter systems, including those used in refrigerators, showers, pitchers, reverse osmosis water purifiers, and backpacking water filters.
The process of making carbon filters for water filtration involves grinding up a carbon source.
Possible carbon sources include:
- Asphaltic coal
- Peat
- Copra shells
Coconut or Copra shells are the most extensively used and most renewable of the aforementioned carbon sources.
The material is heated to 1000 degrees in the absence of oxygen to bake off contaminants in order to make a filter. The carbon is then "activated" by the addition of steam heated to 1600 degrees. Granules of carbon are left with pores and fissures from the steam, which allows them to store a lot of pollutants and chemicals.
Through adsorption, carbon filters get rid of impurities. Adsorption describes how impurities are drawn to the activated carbon's surface and retained there, similar to how a magnet draws and holds iron filings.
Additionally, carbon filters function as a catalyst to alter the chemical structure of some pollutants. Activated carbon is capable of removing a variety of VOCs including those present in gasoline, solvents, and industrial cleaners, organic substances like pesticides, THMs like chloroform, and chlorine.
In the process of purifying water, carbon filters are essential because they eliminate all undesired chemicals and organic compounds including pesticides, chlorine, and other volatile organic compounds (VOCs) that may be present. They also enhance the flavour of water while being excellent at eliminating odour and smell. All of these pollutants, as well as the unpleasant taste and organic compounds, are absorbed by the activated carbon particles in a carbon filter as water runs through it. Both the pre-RO and post-RO purification steps employ carbon filters. Let's examine each's significance and advantages.
Carbon Pre-RO Filter
Before water reaches the RO membrane, a pre-RO carbon filter removes as many contaminants as feasible. The benefit of the carbon filters' greater surface area, where all dissolved compounds are drawn to the carbon particles on the surface, is the fundamental reason for this. The carbon filter is referred to as a Pre-RO Carbon filter at this point. By shielding the RO membrane from chlorine, which is known to shorten the membrane's lifespan by widening its pores, the pre-RO carbon filter also extends the membrane's lifespan. Low maintenance costs for consumers are a result of the RO filter's long lifespan. Water still has certain pollutants, including TDS, which need to be removed after going through the carbon filter.
To do this, further purification steps like RO and UV are included to guarantee that the filtered water is completely clean and suitable for consumption. It's crucial to have the service technician check the carbon filters' lives during any RO water purifier service to make sure they're in top condition.
Post-RO Filter
A post-RO carbon filter is a layer of carbon that is added after the RO and UV purification phases of water filtration. Typically, the post-RO carbon filter comes after other water purification steps. The stage of water purification using a carbon filter contributes to improving the water's quality. It works as a polisher, enhancing the flavour of filtered water even more. The high-quality shells of the activated carbon used in Pureit carbon blocks are produced using a patented process that ensures a maximum amount of active surface area for the absorption of these contaminants. The Pureit carbon block effectively eliminates chlorine and other impurities down to the last drop of cleansed water.
It is strongly advised to use a RO water purifier with carbon filters for water filtration. It is crucial to invest in the best water filtration system so that you and your family members can have access to clean, safe drinking water.
What Kind of Impurities Are Removed from Your Water by Carbon Filters?
Drinking water contaminants are greatly reduced by activated carbon, which is an efficient filter. But which particular pollutants are removed by activated carbon filters?
In general, carbon filters get rid of at least 81 contaminants and successfully lessen 52 more. The Environmental Protection Act states that only activated carbon is capable of filtering out all 12 identified herbicides, all 14 specified pesticides, and all 32 identified organic pollutants.
Additionally, chlorine and other contaminants that degrade the appearance of your drinking water are removed by activated carbon. According to the Centers for Disease Control and Prevention, chlorine is used as a disinfectant in the majority of public water systems in India. However, chlorine can cause compounds that could be carcinogenic as well as a disagreeable taste and odour in tap water. To provide clean water, activated carbon filters out VOCs and chlorine byproducts.
The removal of many more contaminants, including metals like lead, is possible with carbon block filters. Waterborne infections are among the microbiological pollutants that carbon block filters also remove from drinking water.
While no filter can completely rid water of impurities, carbon block filters come close. To make your water as safe and healthful as possible, carbon filtration systems target pollution without removing essential components like minerals.
Filtering Actively to Remove Organics from Drinking Water
Coagulation, sedimentation, and filtration are all used in drinking water treatment to produce water that is safe for consumption. Activated charcoal's ability to purify water is crucial. Impurities adhere to a material's surface due to the physical process of absorption. Additionally, these filters perform better than sand filters at removing dangerous substances from municipal water. Chlorine, heavy metals, byproducts, and other volatile microbes are some of these substances.
Purifying Distilled Beverages
Activated carbon filters assist in the filtration of organic components during the production of distilled drinks. Similar to sewage treatment facilities, the filters improve the beverage's flavour, aroma, and colour. Additionally, they can help in the production of fruit-based drinks and juices for improved texture and fermentation.
