The spinning disc reactor – studies on a novel TiO2 photocatalytic reactor

Treatment options for wastewater effluents from pharmaceutical companies

“…Its photocatalytic activity was 3.8 times higher than a configuration of two TiO 2 slides (which served as an approximation of a TFFBR) (Cernigoj et al, 2007). Other reactors with increased performance include the optical fiber reactor (Danion et al, 2004), corrugated plate reactor (Zhang et al, 2004), fountain reactor with a parabolic profile (Puma et al, 2001), Taylor vortex reactor (Dutta and Ray, 2004), fluidised photo reactors (Lee et al, 2003), Spinning disc reactor (Yatmaz et al, 2005) and labyrinth flow photoreactor with immobilised TiO 2 bed (Mozia et al, 2005). Most of the work to date on photoreactors has been on a laboratory scale, with only a limited number of large-scale applications of photocatalysis to wastewater treatment.…”

Decomposition of formic acid in a photocatalytic reactor with a parallel array of four light sources

“…11 Consequently, various types of photocatalytic reactors with immobilized titanium dioxide have been made; for example,¯uidized-bed type, 12 TiO 2 -coated ®ber optic cable type, 13 multiple tube type, 14 swirl-¯ow type, 15 annular-¯ow type, 16 packed-bed type, 17 rotating disk type, 18,19 corrugated-plate type, 20¯a t sheet polymeric membrane type, 21 thin ®lm cascade reactor type, 22 continuous¯ow bubble column type, 23 and falling ®lm type. 24 Some more improvements, however, are necessary to achieve the practical application of the photocatalytic reactors.…”

Plasmonic photocatalytic reactions enhanced by hot electrons in a one-dimensional quantum well

“…15,16 The SDR is a green technology that provides high processing efficiency and low power consumption while occupying a small physical space. 15,16,[22][23][24][25] The room-temperature oxidation of NH 4 + was achieved under alkaline conditions with the addition of sodium hydroxide (NaOH). A servomotor rotated the glass reaction disk in the reactor at a constant speed of 150 rpm.…”
