Protein skimming removes certain organic compounds, including proteins and amino acids found in food particles and fish waste, by using the polarity of the protein itself. . Due to their intrinsic charge, water-borne proteins are either repelled or attracted by the air–water interface and these molecules can be described as hydrophobic (such as fats or oils) or hydrophilic (such as salt ...
Foam fractionation is a chemical process in which hydrophobic molecules are preferentially separated from a liquid solution using rising columns of foam.It is commonly used, albeit on a small scale, for the removal of organic waste from aquariums; these units are known as "protein skimmers".
Processes similar to continuous foam separation have been commonly used for decades. Protein skimmers are one example of foam separation used in saltwater aquariums. The earliest documents pertaining to foam separation is dated back to 1959, when Robert Schnepf and Elmer Gaden, Jr. studied the effects of pH and concentration on the separation of bovine serum albumin from solution.

Diagram of cross-flow filtration In chemical engineering , biochemical engineering and protein purification , cross-flow filtration [ 1 ] (also known as tangential flow filtration [ 2 ] ) is a type of filtration (a particular unit operation ).
Protein skimmers filter saltwater aquaria; Automated pool cleaners use pressure-side water flow to collect sediment and debris; Clarinets use a reverse taper to speed the air down the tube, enabling better tone, response and intonation [5] The leadpipe of a trombone, affecting the timbre; Industrial vacuum cleaners use compressed air
A separation process is a method that converts a mixture or a solution of chemical substances into two or more distinct product mixtures, [1] a scientific process of separating two or more substances in order to obtain purity.

It is a common observation that when oil and water are poured into the same container, they separate into two phases or layers, because they are immiscible.In general, aqueous (or water-based) solutions, being polar, are immiscible with non-polar organic solvents (cooking oil, chloroform, toluene, hexane etc.) and form a two-phase system.
