title: Evaluation of hybrid treatments to produce high quality reuse water.
abstract: Four tertiary hybrid treatments to produce high quality reused water, fulfilling Brazilian drinking water regulations, from a slaughterhouse's secondary treated effluent were evaluated. The pilot plant with a capacity of 500 L h(-1) was set up and consisted of these stages: pre-filtration system (cartridge filter 50 micron, activated carbon filter, cartridge filter 10 micron), oxidation (H2O2) or second filtration (ceramic filter, UF) followed by UV radiation (90 L h(-1)). The best combination was T4: pre-filtration followed by H2O2 addition and UV radiation (AOP H2O2/UV). Disinfection kinetics by T4 followed pseudo first-order kinetics: k(T4) = 0.00943 s(-1) or 0.00101 cm2 mJ(-1). Three different zones (A, B, C) were observed in the UV254 degradation kinetics (pseudo-first order kinetics): k' decreased over time (k'(A) > k'(B) > k'(C)).
