"Silent Guardian" Bentonite! Why Does It Shine in Industrial Wastewater Treatment?
Bentonite, a non-metallic mineral primarily composed of montmorillonite, plays a vital role across industrial sectors with its unique physicochemical properties, particularly earning the title of "Silent Guardian" in industrial wastewater treatment. How does bentonite excel in this field?
Its exceptional performance stems from three core characteristics: large specific surface area, superior adsorption capacity, and remarkable cation exchange capability. The negatively charged montmorillonite layers with exchangeable calcium, magnesium, and sodium ions enable effective COD reduction and decolorization through pollutant adsorption. In heavy metal removal, bentonite's surface functional groups (-Si-O-, -Al-O-) demonstrate outstanding adsorption efficiency for mercury, lead, chromium and other toxic ions. Acid activation can enhance its adsorption capacity by 40-60% through pore structure optimization.
In textile wastewater treatment, modified bentonite achieves >90% decolorization and >97% COD removal. As a natural coagulant, its stable suspension properties accelerate sedimentation of suspended particles. Through calcination, acid/alkali treatment, and organic modification (e.g., CTAB-bentonite), adsorption performance can be significantly improved for specific pollutants like dyes and petroleum hydrocarbons. With continuous technological advancements, this cost-effective mineral (processing cost <$0.5/m³) is becoming indispensable in industrial wastewater purification systems.
