Abstract

The feasibility of design and performance evaluation of solar trickle down photocatalytic reactor for degradation of cypermethrin pesticide was examined. The optimum operating conditions for treatment of aqueous solution containing 100 to 600 mg L-1 of cypermethrin were observed to be H2O2/COD molar ratio 2, and pH 3. The TiO2 catalyst was coated over glass fibre mesh and was attached to that reactor. The testing was done with and without catalyst.Under the optimum operating conditions, complete degradation of the pesticide occurred in 1 min. Biodegradability (BOD5/COD) increased from zero to 0.36 in 60 min, and COD removal were 74.19 in 60 min. The study indicated that solar photocatalytic process can be used for pretreatment of cypermethrin pesticides in aqueous solution for further biological treatment.
