Clinical Considerations and Dosage

The use of chemicals in sewage water treatment not only helps achieve higher quality effluent but also mitigates the risks associated with untreated wastewater disposal. Many chemicals, such as activated carbon, are employed for adsorbing harmful pollutants, including heavy metals and organic contaminants, ensuring that the discharged water meets regulatory standards.


Phosphate and nitrogen removal often requires the use of specific chemicals. For phosphorus removal, chemical precipitation using ferric chloride or aluminum sulfate is common. These chemicals bind with phosphorus to form insoluble compounds that can then be removed during sedimentation. For nitrogen removal, the process may involve adding sodium nitrate or ammonium sulfate to facilitate biological denitrification, where microorganisms convert nitrates into harmless nitrogen gas.
