Oil filtration systems generally use a multistage filtration with coarse and fine filters. [2] Centrifugation is separation of oil and water, or oil and solid particles by centrifugal forces. Vacuum treatment degasses and dehydrates industrial oil. This method is well suited for removing dispersed and dissolved water, as well as dissolved gases ...
Ion exchange is widely used in the food and beverage industry, hydrometallurgy, metals finishing, chemical, petrochemical, pharmaceutical technology, sugar and sweetener production, ground- and potable-water treatment, nuclear, softening, industrial water treatment, semiconductor, power, and many other industries.

Distillation, widely used in petroleum refining and in purification of ethanol separates volatile liquids on the basis of their relative volatilities. There are several type of distillation: simple distillation, steam distillation etc. Water purification combines a number of methods to produce potable or drinking water.
Step 1: Add flake/powder ingredients to the oil being used to prepare the oil phase. Step 2: Disperse active ingredients. Step 3: Prepare the water phase containing emulsifiers and stabilizers. Step 4: Mix the oil and water to form an emulsion. (Note: This is aided by heating to between 110 and 185 F (45-85 C) depending on the formulation and ...
centrifugation - separates oil into layers (an oil layer, a rag layer, a water layer,) by centrifugal forces; [4] filtration - separates suspensions into clean liquid and wet sediment with the help of filters; [5] Washing with water and dry washing to remove acidic products from oil (water-soluble low-molecular acids, salts of organic acids).
A typical solid phase extraction involves five basic steps. First, the cartridge is equilibrated with a non-polar or slightly polar solvent, which wets the surface and penetrates the bonded phase. Then water, or buffer of the same composition as the sample, is typically washed through the column to wet the silica surface.

Avobenzone in sunscreen may stain clothes yellow-orange and make them sticky if washed in iron-rich water, as it reacts with iron to produce rust. The damage can be undone with a rust remover or stain remover. [34] [35] The staining properties of sunblock made with avobenzone are particularly noticeable on fiberglass boats with white gelcoat.
