1. COMBINED TREATMENT OF VINASSE BY AN UPFLOW ANAEROBIC FILTER-REACTOR AND OZONATION PROCESS
Abstract The aim of the present study was to evaluate the efficacy of treating vinasse using anaerobic digestion (AD) followed by ozonation. The AD process was performed using a laboratory-scale upflow anaerobic filter reactor (UAFR) under continuous operation at 29 ± 1 °C. Stable conditions were reached at 10 kgCOD m-3 d-1 and a hydraulic retention time (

2. Simple model for CO2 absorption in a bubbling water column
A simple analytical model is presented for the time-evolution of dissolved CO2 concentration in a batch water column. The application in mind is the removal of the CO2 produced by the propulsion plant of a submarine cruising underwater. The model is based on a constant number of constant size CO2 bubbles within the water column, with uniform gas injection th

3. AvaliaÃÃo CinÃtica da Taxa de ReaÃÃo de DegradaÃÃo do Ãcido DicloroacÃtico via tecnologia de oxidaÃÃo avanÃada OzÃnio/UV: um estudo cinÃtico
With the current level of industrial activity the quantity of pollutants being rejected into the aquatic environment are constantly increasing. The removal of these products through conventional processes such adsorption, filtration, incineration or biological treatment is not always efficacious, since these methods are based on the simple transference of th

4. Drenagem de espumas usadas em incendios classe B : influencia da presença de polimeros redutores de atrito hidrodinamico
Poly(ethylene oxide), PEO, is one of the most efficient drag reducing polymers. Its application in foam jels for fire-fighting can improve and even assure the fighting efficiency. In order to evaluate the viability of the application of PEO in foams of high stability used in class B fires (inflammable liquids), the effect of the polymer on the stability of f
