Study on the impact of wastewater irrigation on the quality of oils obtained from olives harvested by hand and from the ground and extracted at different times after the harvesting

▶ The treated wastewater can be a source of non-conventional water for irrigation of olive trees. ▶ Storage in mills of fruits from olive trees irrigated by treated wastewater should be avoided. ▶ Fallen olives should be treated separately and should not, under any circumstances, be crushed to obtain edible oil.
