The role of surface aeration in wastewater treatment

Wastewater Treatment Company Malaysia

Wastewater treatment has become an important step to save water and to treat the wastewater so that it could be taken into use for further applications. Wastewater treatment in Malaysia has also been recognized by the locals as well as authorities of Malaysia so as to treat and conserve the water and to save the country from drought. The technique of surface aerator in Malaysia is used in order to treat the wastewater. This process of aeration is taken into use to mix, dissolve or circulate air into liquid, or in this particular case, water.

Mechanical aeration is believed to be reducing the amount of chemicals that are required to treat any water body by the way of providing oxygen which bacteria needs to function well. The process of surface aerator in Malaysia relies on two different types of water aeration namely, subsurface and surface. Both these kinds play an important role in oxygenating the liquids.

The working of surface aeration:

Surface aerators in Malaysia push the water present under the surface into the air where the droplets fall back into the water, thereby mixing in oxygen. The jets of water then break the surface with various degrees of force.

A number of surface aeration devices are used to serve the purpose. The high pumping rate of these devices mix liquids into the water tanks effectively. These devices have low trajectory sprays which produces high oxygen transfer rates. Other devices of surface aeration include bubblers, agitator and fountains. Floating aerators can be taken into use in application like leachate treatment, wastewater treatment, supplemental aeration as well as sequencing batch reactors in order to release unwanted gases from water.

Another device of surface aeration so used is the floating paddle wheel aerators. The rotating blade produce horizontal and strong mixing action which create an oxygen transfer of high rate by the way of mist created by the paddle. These can also be used in groups, thereby creating flow patterns in the tanks and lagoons.

Application of surface aerators in Malaysia:

Aeration is required across a wide range of industrial application in Malaysia including the food processing as well as petrochemical industries and pulp and paper mills. The same use is also taken into application in order to treat agricultural wastes.

Surface aerators can also be taken into use in order to keep the still bodies of water in circulation so that the water remains healthy and free from odor. The same process is also taken into use in the public parks as well as golf course where the decorative water in the appearance comes with special and specific needs to keep the plants and fish healthy.

Factors like heat can prove to be little challenging to the process of surface aeration because of the higher rates of evaporation that has negative effects on some of the applications. A number of aeration technologies are currently available to treat all kinds of water as well as wastewater treatment in Malaysia.
