This study stemmed from consumer complaints about earthy and musty off-flavours in treated water of Rawal Lake Filtration Plant.

In recent years, several novel adsorbents have been developed from nanomaterials for enhancing the contaminant removal efficiency.

This paper presents preparation and the use of new adsorbents Pt doped titania and Fe doped titania, for the adsorption capacity of Geosmin and 2-MIB from water under laboratory conditions and their comparison, with most widely used activated carbon, under batch and column experiments.

Stock solutions were prepared by using Geosmin and 2-MIB standards, procured by Sigma Aldrich (England).

Samples were analysed using SPME-GC-FID.

The adsorption of Geosmin and 2-MIB on GAC conformed to the Freundlich isotherm, while that of adsorption on metal doped titania fit equally well to both Langmuir and Freundlich isotherms.

Moreover, data, generated for the kinetic isotherm, confirmed that Geosmin and 2-MIB removal is a function of contact time.

Breakthrough column tests using 125 mg/L Pt doped titania nanoparticles, coated on glass beads against 700 ng/L of off-flavours, attained later breakthrough and exhaustion points and removed 98% of Geosmin and 97% of 2-MIB at room temperature.

All columns could be regenerated using 50 mL 0.1 molar sodium hydroxide.
