One of the initial and most critical stages of water treatment is to aerate large volumes of water in treatment plants. Aeration is the process whereby water is enriched with oxygen through a continuous rotation and churning process. This enables the release of harmful gases from the water, kills certain bacteria and also hastens the breakdown of organic matter.
Aeration is usually achieved by rotating a large propeller through the water volume, thereby mixing air into the water. This propeller is exposed to large radial and axial forces, and if the drive gear is incorrectly installed, it can lead to failure and damage to the propeller and the gearbox driving it.
SEW-Eurodrive Cape Town branch manager Byron Griffiths notes that the company’s extended bearing distance (EBD) configuration and drywell bearing housing is ideally-suited for the aeration process. “It allows for much higher radial and axial forces to be absorbed by the gearbox, while the drywell bearing housing ensures no oil can leak into the sensitive water treatment process.”
Inenzo Water projects manager Chris Erasmus adds, “In our industry, we must ensure that we offer clients top solutions at competitive prices. Over the years, we have found that the pricing, quality and service offered by SEW-Eurodrive played a decisive role in our procurement for this project.”
Griffiths indicates that the company has extensive application knowledge with regards to gearboxes driving aeration equipment. “By listening to the client’s requirement and understanding the unique problems faced on this project, we were able to marry our own extensive product range and knowledge with the expectations of the client.”
SEW-Eurodrive strives to ensure that every application requirement is fully understood and that each product delivered meets with the high standard of service and quality that its clients have come to expect over the decades. Griffiths reveals that the compact range of IG units is becoming increasingly popular in South Africa.
One of the key advantages in selecting the MC series of IG units is that they are assembled in Nelspruit. Griffiths points out that local assembly cuts down on international shipping costs, which results in savings for the client.
“The units can also be produced faster, which reduces project lead times. Availability of spares and turnaround time on repairs is also minimised to ensure high levels of availability. Due to our having the expertise to assemble these units in South Africa, extra degrees of customising and order flexibility are also axailable to our customers,” he concludes.
