The Protein Skimmer is mainly used for separating the organic residues contained in recycling water in large aquarium tanks, but it has also proved to be excellent in pre-treatment of salt water in reverse osmosis plants. It works according to the principle of separation through foam. This process uses tiny bubbles (Fig.1) mixed with salt water to create a foam of waste products. The foam is then evacuated, carrying the organic waste itself.
The bubbles are insufflated from the bottom of the tank, along with the water to be purified; As the micro bubbles rise, they capture, by the effect of surface tension, a thin film of organic material that is pushed to the top of the reservoir. Once they get at the water surface, the bubbles burst, the organic material is released and appropriately conveyed to the collection area on the top of the Protein Skimmer. From there, once enough organic residue is accumulated, a rinse is carried out to evacuate the waste.


In Aron S.r.l. We build Protein Skimmer with high-quality, water-resistant and non-toxic materials, with production technologies consolidated over years of experience.
The size of the Protein Skimmer depends on the water flow to be treated, but the structure is essentially the same for each model. It consists of a polypropylene lower tank (also available in a transparent version), where the water mixed with air (or air-ozone mixture) coming from one or more recirculating pumps is collected. At customer discretionary, the tank top, where the waste foam is collected and rinsed out from the system, can be transparent or opaque.
