High performance skimmers
Skimmers made by SCHURAN seawater equipment following the Aquaflotor-principle are made since more than 20 years. They are in use since then and have produced convincing results, if under tropical or even polar conditions. These skimmers performances are outcompeting those of usual skimmers by far.
The backgound of enhanced performance of Aquaflotor-skimmers:
To get the highest concentration of protein skimmed off, the proteins have to form complexes called micelles. These are made of protein molecules which fuse with each other forming a macromolecular networks. But this can happen only under calm and undisturbed conditions! Currents, turbulences or chaotic convections are contraproductive and cause the micelles to break into pieces before they can be skimmed off. Contact time between water and bubble is another character of eminent importance. The longer the time is the more protein a bubble can collect on its surface. This contact time is several times longer than in usual and unchambered skimmers. It is neither the amount of water flow nor the amount of air sucked in alone which causes good results, but more than this it is the constructional set up which cause the enhancement.
Ozone – enhances skimming but with the right skimmer only !
Ozone is still used in fishfarming systems without skimmers. This do not cause a removal of the protein but only an oxidative breakdown to nitrite and nitrate and accumulate over a period off time and cause splendid growth of algae. Therefore a high percentage of water has to be exchanged regularly. Besides water with a higher ozone level or redox potential can be very harmful to animals´ skin.
If used in skimmers ozone can have very beneficial effects. However it can be can be used much better in Aquaflotor skimmers than in unchambered skimmers and can be even reduced in its amount in comparison to unchambered constructions. The chambering of the skimmers cause the bubbles to go there where they have the effect they should have. They do not leave the skimmer and cannot go over the expansion cone.
Quality of Aquaflotor skimmers:
Skimmers are units which should be durable and for a use over lots of years. They should guarantee best performance instead of malfunctions. On the one hand such units should work with high efficiency and should be subject of energy saving. Daily use makes it quickly obvious if skimmers are servicefriendly. The usual skimmer has to be cleaned every some days to guarantee a continuous performance.
Aquaflotor skimmers are optimized concerning these characteristics: They are made of high quality materials only and are products of best manufacturing. Aquaflotor skimmers have a construction which uses a single pump only and save therewith a lot of energy. Daily service can be reduced to a minimum due to Aquakat, a selfcleaning device which holds the foampot´s tube clean for periods over several months. Especially when several skimmer are used in Zoos a lot of work and costs can be saved.
Height:
Even the largest skimmer, AQ800, only have a size of 2,5m and only need a standfloor of 1x1m., additionally a little space is necessary for the pump. Aquaflotor-skimmers therefore have proportions which enable them to be integrated into elder buildings, but small standfloor also means small water volume in the skimmer. The weight of a filled skimmer is in those dimensions which is still suitable for an average carrying capacity of a buildings floor.
Resumee:
The use of Aquaflotor-Skimmer causes a more intense removal of protein contrary to usual skimmers and makes perfect use of ozone possible. The skimmers work in energy saving mode and are servicefriendly. They can be readily integrated into most buildings due to their compact construction. As basic condition to gain all the mentioned functional advantages is the exact dimensioning of the skimmers, suitable integration into the rest of the filtration system.
