Advanced Treatment Solutions
A method that removes contaminants in wastewater by adding chemicals to induce physical and chemical reactions such as oxidation, reduction, and coagulation of organic/inorganic colloidal solids, heavy metals in dissolved state, and various pollutants.
A method that removes organic matter in wastewater using the biological decomposition action of microorganisms, efficiently reducing degradable organic substances.
