PHOSPHATE REMOVAL PROCESS

The present invention provides a process for a treatment of phosphate rich effluents wherein the process comprises exposure to acid pH of a microorganism which is stimulated by this exposure to accumulate enhanced levels of inorganic phosphates. The microorganism can be one organism or a mixture of...

Beschreibung
Zusammenfassung:	The present invention provides a process for a treatment of phosphate rich effluents wherein the process comprises exposure to acid pH of a microorganism which is stimulated by this exposure to accumulate enhanced levels of inorganic phosphates. The microorganism can be one organism or a mixture of organisms. Preferably the microorganism is exposed to acid pH at pH 4.5 to pH 6.5. La présente invention concerne un processus de traitement d'effluents riches en phosphate, consistant à les exposer au pH acide d'un micro-organisme stimulé par cette exposition de façon à accumuler des taux élevés de phosphates inorganiques. Ce micro-organisme peut être un seul organisme ou un mélange d'organismes. De préférence, ce micro-organisme est exposé à un pH acide compris entre 4,5 et 6,5.
