Activated carbon filters for water treatment

Activated carbon filters are formed by a porous carbon based filter media that traps and absorbs water contaminants, mainly organic and chemical. It is a high efficiency compound that has been used for water purification for several years giving excellent results in the treatment of drinking water and wastewater.

It is common to use activated carbon filters for the treatment of industrial and well water because it is one of the most used compounds and with the widest range of application in water engineering projects.

 
Fields of application of activated carbon in water treatment:

Activated carbon systems have a wide range of application in water treatment:

• Drinking water treatment plants: Activated carbon is responsible for retaining pesticides, organic matter, toxins, some chemicals and odor and taste of drinking water from wells, rivers, lakes and rain. This process results in odor and taste free water suitable for disinfection and human, animal or irrigation consumption.
• Dechlorinating filter: Activated carbon filters are used as a system to remove chlorine from water when necessary, favoring industrial processes and water purification for irrigation and agriculture.
• Reuse of graywater and wastewater: This type of carbon water treatment equipment is used in the treatment of wastewater due to its ability to reduce chemicals, COD and color of graywater and wastewater, favoring its reuse for irrigation and cleaning or discharge.
• Removing odor and taste from water: Activated carbon is a chemical compound specially designed for the absorption of unpleasant odors and tastes from well, river or stagnant water. This helps to make it suitable for human consumption.

Operating parameters of activated carbon filters:

Our filtering equipment works with a mineral activated carbon filter media at a maximum working pressure of 10 bar, being 3 bar the ideal working pressure for the filter to work properly and have a long service life.

The filtration process is based on the passage of the water to be treated under pressure through the inside of the equipment, creating an overpressure inside the equipment and providing sufficient contact time between the water and the activated carbon bed to promote the filtration and absorption of the compounds to be removed, such as herbicides, chlorine, pesticides, odors and flavors from the water.

To select the right IMA water filter it is necessary to know the flow rate of the water to be treated with it. Based on this flow rate there is a wide range of sizes of carbon filters ranging in diameter from 300 mm to 1600 mm.

Finally, when the filter has become dirty after several days or weeks of treatment, it will perform a backwash to remove any compounds that have been deposited on the filter media and thus be able to continue working without the need to replace the carbon until it has exhausted its characteristics. When it is observed that the activated carbon has exhausted its adsorption capacity, it should be replaced by a new load. The replacement time will be related to the characteristics of the water to be treated and can vary between several months or years.

As an example to be able to have a replacement order, for a standard well water present in nature it is recommended to replace the charge every 2-3 years.

Activated carbon filters for industry, agriculture and water treatment plants.

The range of IMA water industrial filters covers a wide range of sizes and flow rates that can be applied from domestic and residential uses to large industrial and municipal water treatment plants.

Carbon filters are categorized by size and/or flow rate.

1. By size: IMA water filters have a size range from 300 to 1600 mm filtration diameter.
2. By flow rate: IMA water filters can be used for flow rates from 0.5 m3/h to 6000 m3/h.
