Expanded clay aggregates multi-functionality for water purification: Disinfection and adsorption studies

Elevated levels of contaminants in surface and ground water pose serious adverse health challenges the twenty-first century. It is imperative that quality life people without safe drinking improved by providing safe, clean affordable using appropriate purification technology. Natural clay rice husk-Na2CO3 modified were used to produce expanded aggregates adsorbents. Characterizations done SEM, XRD, XPS BET reveal their salient features. Filtration studies carried out ascertain disinfection assay E. Coli removal efficiencies nitrate phosphate. Batch adsorption experiments employed determine effect pH, contact time adsorbent dosage for effective Arsenic (III) lead (II) including isotherm models. Aluminosilicates associated minerals with high areas between 456.143–566.998 m2/g significant sites revealed. Log four bacteria was achieved. Reduction phosphate all adsorbents varied from 27.33% 76% 10.67% 46% respectively. High correlation coefficients made Langmuir model more favourable than Freundlich model. The capacities both arsenic reaction fast, making suitable remediation applications.
