Abstract This study seeks to investigate the use of a surfactant derived from coconut oil in recovery process organic compounds oily effluents. To evaluate its efficiency removal and optimal concentration for each oil/water ratio, experiments were carried out using water/oil emulsions (50, 100, 200, 400 ppm oil) produced water (50 ppm) small-scale column. According these experiments, it was verified that there is an optimum emulsion, extraction reaches maximum value (80%) at 0.1 g/L−1.
Abstract The aim of this paper was to evaluate the performance two modified upflow anaerobic reactor (RAns) as a decentralized technology for treatment high-strength domestic wastewater. Two full-scale reactors (Ran1 and Ran2) with same configuration total volume 14.6 m³, height 2.57 m, constructed from fibreglass reinforced plastics were operated 16-hour hydraulic retention time submitted volumetric organic load less than 2.7 kg chemical oxygen demand (COD)·m−3·d−1. RAns monitored 10...
Propõe-se um novo modelo de escadaria drenante para solucionar problemas existentes em algumas escadarias convencionais. As equações Navier-Stokes com médias Reynolds, conservação massa e o turbulência k-ε foram utilizadas simular escoamento na escadaria. Os tipos escoamentos, a energia dissipada fator resistência apresentaram aderência dados experimentais da literatura. O padrão estabelecido escada indica haver baixo risco queda pessoas. Alturas máximas calculadas, possibilitando...
