3. ADSORPTION Adsorption is a method of wastewater purification called adsorption can be used to extract a variety of substances from industrial effluent. Adsorption is most frequently used as a tertiary cleansing step following, say, biological water purification, or for the removal of low quantities of non-degradable organic contaminants from groundwater, drinking water preparation, process water, or other sources.

5. PROCESS OF ADSORPTION Activated carbon is utilized in wastewater purification processes, added as powder and subsequently removed with sludge. It is employed in both physio-chemical and aerobic/anaerobic systems. In industrial settings, closed filters force liquid through granular or pelletized carbon to remove contaminants efficiently. Open filters used in drinking water treatment rely on gravity to pass water through carbon beds. Carbon columns operate with downward flow, becoming saturated over time and thereby reducing effectiveness until thermal regeneration in high-temperature ovens removes adsorbed organic chemicals, restoring adsorption capacity.

9. CONCLUSION Adsorption offers multiple advantages in waste management, including effective pollutant removal, versatility, cost-effectiveness, and environmental compatibility, making it a valuable technique in sustainable waste treatment strategies. Adsorption remains a valuable tool in waste management, particularly when integrated with other treatment technologies to address specific challenges and optimize overall efficiency in pollution control and resource recovery.
