What are the features of carbon filters & purification processes?

Carbon is a filtering medium that is widely used while filtering water. In fact, practically all types of water filtration systems, including those used in reverse osmosis water treatment plants filters use carbon filtration.

Let’s look at the features of the carbon filters, and their contribution to the supply of clean and pure water.

Sources of carbon

In order to create carbon filters for water filtration, a carbon source must be ground up. The potential sources of carbon include:

· Shells of copra,

· Peat,

· Asphaltic coal, and much more.

The most widely applied and regenerated of the aforementioned carbon sources are coconut or copra shells.

How is carbon filter made?

To create a filter, the material is heated to 1,000 degrees without any oxygen present, in order to bake off impurities. The addition of steam heated to 1600 degrees then "activates" the carbon. The pores and fissures that the steam leaves in the carbon granules allow them to store, a lot of contaminants and chemicals.

How are impurities filtered in water using activated carbon?

Impurities are eliminated by carbon filters through adsorption. Adsorption is the process by which contaminants are attracted to the surface of the activated carbon and held there.

Carbon filters also act as a catalyst to change the chemical make-up of some contaminants. Many VOCs, including those found in gasoline, solvents, and industrial cleaners, as well as organic compounds like pesticides, THMs like chloroform, and chlorine, can be eliminated with activated carbon.

Why are carbon filters important in water purification processes?

Carbon filters are crucial in the process of cleaning water, because they remove all undesirable chemicals and organic molecules, including pesticides, chlorine, and other potentially present volatile organic compounds (VOCs).

They are effective in removing odour and smell and also improve the flavour of water. The activated carbon particles in a carbon filter adsorb all of these contaminants, as well as the bad taste and organic compounds, as water passes through it.

Features and benefits of carbon filters

Carbon filters are used in the pre-RO and post-RO water purification processes. Let's look at the importance and benefits of carbon filters:

· Pre-RO Carbon Filter

A pre-RO carbon filter gets rid of as many impurities as it can from the water before it gets to the RO membrane. The primary cause of this is the benefit of the larger surface area of carbon filters, where all dissolved chemicals are pulled to the carbon particles on the surface. At this time, the carbon filter is referred to as a Pre-RO Carbon filter.

The pre-RO carbon filter also prolongs the life of the membrane by protecting it from chlorine, which is known to diminish the membrane's lifespan by enlarging its holes. The long lifespan of the RO filter results in low maintenance expenses for users. After passing through the carbon filter, TDS must still be removed from the water along with other contaminants.

To achieve this, further purification processes like RO and UV are added to ensure that, the filtered water is 100 percent clean and safe to drink. During any RO plant service, it's critical to have the service professional verify the carbon filters' condition and lifespan.

· Post-RO filter

After the RO and UV purification stages of water filtering, a layer of carbon is added as a post-RO carbon filter. Usually, other water purification stages happen before the post-RO carbon filter. The stage of water purification that uses a carbon filter helps to raise the standard of the water. It functions as a polisher, increasing filtered water's flavour even further.

A proprietary technology is employed to create the premium activated carbon shells, used in Netsol’s activated carbon filters, ensuring a maximum amount of active surface area for the absorption of harmful pollutants. Chlorine and other pollutants are completely removed from the water by these activated carbon blocks.

Which impurities are taken out of water by using carbon filters?

Activated carbon is a powerful filter that effectively reduces pollutants in drinking water. But which specific contaminants do activated carbon filters remove?

In general, 52 pollutants are successfully reduced and at least 81 are eliminated using carbon filters. According to the Environmental Protection Act, only activated carbon can effectively filter out all 12 known herbicides, all 14 known pesticides, and all 32 known organic contaminants.

Activated carbon also gets rid of chlorine and other impurities that ruin the appearance of your drinking water. The majority of public water systems in India use chlorine as a disinfectant, according to the Centers for Disease Control and Prevention. Yet, chlorine can produce substances that might be carcinogenic, as well as give tap water a bad flavour and odour. Activated carbon removes VOCs and chlorine by-products to produce clean water.

Using carbon filters with RO purification, a great deal pollutants, including metals like lead, can be eliminated. Carbon filtration systems target pollutants without eliminating key components, like minerals to make your water as safe and healthy as possible.

How do carbon filters contribute to the supply of clean water?

· Activated carbon actively filtrates drinking water to eliminate organics

To create drinking water that is safe for ingestion, coagulation, sedimentation, and filtration are all used. The capacity of activated carbon to cleanse water is essential. A material's surface becomes imprinted with impurities, as a result of the physical adsorption process.

Furthermore, these filters are more effective at eliminating harmful contaminants from municipal water. Some of these chemicals include chlorine, heavy metals, by-products, and other volatile microorganisms.

· Purification of distilled water

When making distilled beverages, activated carbon filters help with the filtration of organic materials. The filters enhance the flavour, aroma, and colour of the beverage in a manner similar to sewage treatment facilities. Moreover, they can aid in the juicing and blending of fruit to produce beverages, with better texture and fermentation.
