Plant material from olive drupes is suspended in oil due to lack of the filtering step, along with microdroplets of vegetative and non-vegetative water in small amounts (0.1–0.3%) forming in a water-oil emulsion. Unfiltered olive oil initially has higher levels of phenolics that form a complex polyphenol-protein complex. This complex ...
In crude olive oil production, the traditional system, i.e. pressing, and the three-phase system produce a press cake and a considerable amount of olive mill waste water while the two-phase system, which is mainly used in Spain, produces a paste-like waste called "alperujo" or "two-phase pomace" that has a higher water content and is more difficult to treat than traditional solid waste.
Induced gas flotation (IGF) is a water treatment process that clarifies wastewater (or other waters) by removing suspended matter such as oil or solids. The removal is achieved by injecting gas bubbles into the water or wastewater in a flotation tank or basin.

A cold press olive oil machine in Israel Olive oil mill. Olive oil is produced by grinding olives and extracting the oil by mechanical or chemical means. Green olives usually produce more bitter oil, and overripe olives can produce oil with fermentation defects, so for good olive oil care is taken to make sure the olives are perfectly ripe.
The effective removal of oils and grease is dependent on the characteristics of the oil in terms of its suspension state and droplet size, which will in turn affect the choice of separator technology. Oil in industrial waste water may be free light oil, heavy oil, which tends to sink, and emulsified oil, often referred to as soluble oil.
Although oxidation processes involving ·OH have been in use since late 19th century (such as Fenton's reagent, which was used as an analytical reagent at that time), the utilization of such oxidative species in water treatment did not receive adequate attention until Glaze et al. [1] suggested the possible generation of ·OH "in sufficient ...
Maceration can be achieved by using a chopper pump in the sewage lift station or at the wastewater treatment plant. [ 1 ] When the flush is triggered, wastewater flows into the macerator, and when the water level rises, pressure activates the unit, causing the stainless steel blades to rotate at 3,600 rpm, pulverizing the wastewater into fine ...
