Purification of wastewater from olive oil, by mechanical, chemical and biological methods

摘要

Method for purification of wastewater from olive oil production, in which the wastewater is flocculated, preferably by Ca (OH) 2, then subjected to ultrafiltration or nanofiltration, and finally undergoes a reverse osmosis, characterized in that in a first stage, the wastewater is allowed to decant, at least, for two to three months, and because the purified wastewater is subjected to oxidation, preferably oxidation with hydrogen peroxide and ultraviolet radiation
