SC and SCL Series Radial Submersible Aerators
Submersible aerators represent a flexible and versatile aeration system suitable for application in civil and industrial plants for purifying and treating sludge and liquids. Let’s take a closer look at the features of SC and SCL series radial submersible aerators made by SCM Tecnologie.
SC-SCL radial submersible aerators from SCM Tecnologie
Radial submerged aerators such as the SC and SCL series from SCM Tecnologie can be installed and used in civil, industrial or livestock purification plants.
This aeration system is extremely effective when there is a need to functionally mix liquids while incorporating air.
All this is achieved by means of a simple but extremely functional mechanism. Specifically, it is a self-priming aerator with a submersible motor that can be installed and operated at the bottom of a tank.
Operation is based on a star-shaped impeller coupled directly to the motor shaft without the need for any transmission components.
The other main components are a stator concentric to the impeller and an air intake pipe. The impeller rotates within the stator in such a way as to create the conditions needed to suck air from the atmosphere through the intake pipe.
At the same time, water flows into the impeller and thus comes into contact with the air. The channels in the stator then allow the resulting liquid and air mixture to be discharged radially. The end result is really important because these radial submersible aerators are designed and manufactured with the aid of the latest innovations in the sector to provide SAE and SOTR values that are 15 or 20% better thanks to the extended expulsion channels available on the SCL series.
Key benefits of SC-SCL radial submersible aerators
The SC-SCL models of radial submersible aerators made by this historic brand in the sector offer significant benefits that translate into great versatility. In fact, these products can be used in a wide variety of sectors, while ensuring excellent results.
The main benefit that submerged aerators offer is related to their ability to work on the bottom of a tank, and consequently prevent the formation of deposits and sedimentation that can lead to loss of efficiency in treatment processes.
The same principle also prevents the formation of aerosols, ensuring a better environment for operators and nearby residential areas.
Oxygen transfer efficiency, known by the abbreviations SOTR and SAE, is also favoured by the time the bubbles remain in the liquid, and this allows SC and SCL aerators to achieve significant levels for these parameters.
Aeration efficiency can reach even higher values when using the SCL series, which is designed with extended expulsion channels. Furthermore, these channels can be customised to meet specific needs, so they can be extended if necessary or shaped in such a way as to maximise contact time.
There are also indisputable benefits in terms of installation and fitting. Technicians will also have an easy time thanks to the compactness of the device. In this case, installation and maintenance work can be carried out without having to empty the tank or, worse still, having to shut down the purification plant. Furthermore, the materials and manufacturing techniques used ensure that these products provide good mixing, high transfer of oxygen and more generally of air into the liquid, as well as a long service life as they are very reliable. Finally, the fact that they require infrequent maintenance is not to be overlooked and is important in reducing plant running costs.
Application fields
The versatility of SC-SCL radial submersible aerators is among their main strengths. Specifically, they prove effective in basins for equalising and homogenising wastewater at variable load or flow rates, as well as for preventing odour formation.
They are also used in activated sludge basins and SBR processes to biologically break down organic substances, and are equally useful for stabilising sludge, preventing odour formation and helping to complete biological oxidation.
They can also be applied in oil and fat floatation or in lagoons to further improve the existing natural aeration. Radial submersible aerators can also serve the needs of those with alkaline waste water neutralisation tanks, where they can make the best use of carbon dioxide and other combustion gases.
Construction and installation of aerators
These devices are very simple to install precisely because of their distinguishing characteristics. Since they are submerged aerators, they must necessarily be placed at the bottom of a tank. No anchoring is required, and they can be removed using a mobile crane for maintenance purposes or simple inspection to assess their functional status.
These machines are suitable for all kinds of civil or industrial liquids, and can be fed with carbon dioxide and various types of combustion gases.
Finally, they can be removed from the tank without problems and without the need to empty it.
There are many good reasons to rely on SC and SCL series radial submersible aerators from SCM Tecnologie.
S.C.M. Tecnologie is available to analyse liquid properties, design data and tank geometries, and guide the customer through dimensioning the units needed and positioning them in the tank for effective and efficient aeration at all times.
