The world is ever changing but, in recent times, this change is occurring in a unique manner. Newer services and technologies are emerging every year. Now, this evolution, besides having a positive impact on human lives, is also increasing consumption of different resources. Consumption is also increasing because of growing population in this country. Products have to be manufactured in factories and they operate by using resources like fuel, water and other kinds of chemicals.
Now, here arises the problem! Natural resources in India has limited supply and wasting of artificial resources leads to pollution and hence, to increase in costs.
How Significant Purification and Recycling Is
Earlier, people used different resources like gases, chemicals and water in manufacturing industries and then released them into the environment. This not only polluted the atmosphere but also created an imbalance in nature. As a result of this action, scarcity of resources is created in the future. This future, with inadequate resources and polluted environment, would not be good for businesses or mankind. Therefore, if you wish to enjoy the luxuries and comfort of modern technologies, then you have to minimize consumption of natural resources and reduce their adverse effect.
In modern world, technologies and products have already started evolving that minimize wastage of resources and lessen the impact of waste matter on environment. Industries have also started taking measures for purifying liquid wastes, smoke and gases before discharging them. They are also exploring new ways for recovering used resources such as chemicals and water.
Role of Activated Carbon in Purification and Recycling
Activated carbon is used for adsorption in recycling and purification. What is adsorption? It is a process where molecules, ions and atoms in a fluid adhere to some solid surface and are removed from the fluid. Now, why activated carbon is used in adsorption? It is because of the micro porosity of activated carbons, which offers large surface area. It is due to non-hazardous nature and vast surface area of activated carbon that it is used as adsorber in a large scale.
Another advantage of using activated carbon is, after completing the adsorption process, this carbon can undergo desorption for recovery or removal of adsorbed molecules from its surface. Moreover, activated carbon requires minimum contact time for performing its job. As compared to general separating process, activated carbon is more effective in removing molecules or impurities that have very low weight.
Advanced technology enables us to use activated form of carbon. During its activation process, carbon undergoes several processes for enhancing the adsorption capability. Many complex issues can be resolved by utilizing activated carbon with advanced purification and filtration equipments. The areas where adsorption quality of activated carbon is used –
- Air Purification
- Water Treatment
- Biogas and Natural Gas Purification
- Waste water Treatment
- Automotive Emission Control
- Chemical Purification
- Pharmaceuticals
- Treating Industrial Gases and Smoke
- Food and Beverage
- Vapor Recovery
- Catalyst Recovery
Now, activated carbon is of three types – extruded, granular and powered. You can make the right selection of the carbon after knowing the real nature of the fluid in which it is to be used.
