Definitions

  • the reverse osmosis network 130 utilizes RO membranes to removes the final traces of BOD.
  • the RO membranes 131 can be structured as thin film composite with the top layer made of cellulose acetate, polyamide, polyimide, or polyacrylonitrile.
  • the top layer can be impregnated with various amounts of zeolites or other inorganic fillers to improve flows and rejection limits of solutes.
  • the reverse osmosis network 30 may be any known reverse osmosis network 130 such as being a single or a multi stage reverse osmosis network 130.
  • Coarse suspended solids can be removed by filtration, centrifuge, dissolve air flotation, coagulation, flocculation, or any combination of these technologies as required by the particular work site conditions.
  • the goals of cleaning up the vinaza or any other comparable waste stream 40 is to reduce the Total Suspended Solids (TSS) and total Dissolved Solids to somewhere less than 1000 ppm prior to any membrane treatment.

Abstract

La présente invention concerne un système de traitement des eaux usées destiné à être utilisé pour réduire les taux de polluants dans des flux d'eaux usées de vinasse, à savoir des flux d'eaux usées de distilleries de tequila. Le système est particulièrement efficace pour réduire les valeurs des matières totales en suspension (TSS), des matières totales dissoutes (MDT), de la demande biologique en oxygène (DBO) et de la demande chimique en oxygène (DCO) sous des seuils acceptables. Le système de traitement des eaux usées comprend les éléments interconnectés d'une unité d'élimination de matières à gros grains en suspension, d'une unité de filtration grossière, d'une unité d'ultrafiltration, d'une unité de nanofiltration et d'un réseau d'osmose inverse. L'eau obtenue en sortie d'un tel système pourrait être conforme aux normes de qualité de l'eau potable.
