Title
(EN) SYSTEM FOR TREATING PALM OIL MILL EFFLUENT
(FR) SYSTEME DE TRAITEMENT D'EFFLUENT D'USINE DE TRITURATION D'HUILE DE PALME
Abstract
(EN)
A system for the treatment of palm oil mill effluent which utilizes different organisms for bioremediation at different stages of the treatment process. The method allows the oil palm mill by-product to enter a complete food chain, with production of high-value fish protein as an end product. The crude oil, obtained from the pressing of the sterilized fresh fruit bunches, is separated into oil and sludge followed by the separation of the sludge into sludge solid and sludge liquor. The sludge solid is first treated by digestion in animals to form animal excreta. The excreta is then converted to microorganic biomass in an aerated pond or fed to fishes directly. The biomass is then converted to high-value protein product by feeding the biomass to fishes in one or more fish ponds. The sludge liquor is first converted to microorganic biomass by microorganic digestion, preferably in a bioreactor. The biomass is then converted high-value fish product by feeding the effluent of the bioreactor to fishes in the fish pond. The effluent from the fish pond may be further treated to meet effluent requirements before being discharged into the environment.

L'invention concerne un système de traitement d'effluent d'usine de trituration d'huile de palme faisant intervenir différents organismes pour obtenir une biorestauration à différents stades du processus de traitement. Grâce à ce procédé, le sous-produit d'usine de trituration d'huile de palme peut être introduit dans une chaîne alimentaire complète qui aboutit à la production de protéines de poisson à haute valeur en tant que produit final. On sépare l'huile brute, obtenue par le pressage des bottes de fruits frais stérilisés, en huile et en sédiments, puis on sépare les sédiments en sédiments solides et en liquide sédimentaire. On traite les sédiments solides en les faisant digérer par des animaux afin d'en obtenir les excréments, lesquels sont ensuite convertis en biomasse micro-organique dans un étang aéré ou directement donnés comme nourriture aux poissons. On convertit ensuite cette biomasse en produit à protéines à haute valeur, en donnant cette biomasse comme nourriture aux poissons dans un ou plusieurs étangs de pisciculture. Le liquide sédimentaire est d'abord converti en biomasse micro-organique par digestion micro-organique, de préférence dans un bioréacteur. On convertit ensuite cette biomasse en produit à base de poisson à haute valeur, en donnant l'effluent du bioréacteur aux poissons de l'étang. L'effluent issu de l'étang de pisciculture peut être de nouveau traité afin de satisfaire aux exigences des effluents avant d'être évacuer dans l'environnement.
