Coagulation and electrocoagulation of oil-in-water emulsions
The electrocoagulation and the conventional coagulation with hydrolyzing aluminium salts can be successfully applied to the treatment of oil-in-water emulsions. The efficiency of the processes does not depend directly on the dosing technology but on the total concentration of aluminium and pH.

Removal of Emulsified Oil from Water by Coagulation
Abstract A new method of emulsified oil separation for oily wastewater incorporating simple operation and shortened treatment time is necessary for improved wastewater treatment in some manufacturing plants. In the present study, the removal of emulsified oil from water by coagulation and foam separation using poly aluminum chloride (PAC) and milk casein was examined.

Treatment of oil-in-water emulsion by ultrafiltration (uf
In the past, the used emulsion was often discharged into either sewers or public waterways without previous treatment, causing environmental pollution and loss of oil. Conventional approaches for treating oily wastewaters have included gravity and skimming, dissolved air flotation, de-emulsification, coagulation and flocculation.

Oily Water Treatment: How to treat using Advanced
Emulsions can occur by mechanical means, like whisking a pot of oil and water, but these are unstable emulsions that will separate out quickly, leaving only the smallest droplets suspended. Chemical emulsions on the other hand typically introduce an emulsifier that stabilizes the suspension by reducing the forces between the droplets and the water.
