Disc Diffuser AS-DD215 Advantage
As a professional manufacturer of Disc Diffuser, our products are made of EPDM material with "bimodal" molecular weight distribution. This unique choice of material not only gives our products excellent strength and high elasticity but also provides good tear resistance. What's more, our products are designed with a unique anti-clogging concept that ensures that there is no risk of hole clogging for 8 years, which greatly enhances the product's service life and reliability. In addition, our oil-free formulation reduces the impact of sewage media on the rubber compound, further ensuring product stability and durability in a variety of environments. These features combine to make our disk aerators an efficient, reliable, and low-maintenance solution in wastewater treatment.
Disc Diffuser AS-DD215 Sea Water Desalination (As A Pre-Treatment Step) Application
1. Gas transfer: disc diffuser facilitates contact between gas and water by introducing gas (usually air) into the water. This contact creates bubbles in the water and transfers the gas to the water. During the pre-treatment stage, these bubbles can help increase the level of dissolved oxygen in the water, thus contributing to the biological reaction or oxidation process in subsequent treatment processes.
2. Mixing: By creating bubbles in the water and forming convection currents, disc diffuser helps in mixing the substances in the water. This mixing helps to evenly disperse the dissolved substances in the water, preventing uneven distribution of substances or precipitation during the treatment process.
3. Pre-treatment: In desalination, an important goal of the pre-treatment stage is to remove suspended solids, organic matter and other impurities from the seawater. By creating bubbles in the water and creating convection currents, the disc diffuser facilitates the separation of these impurities from the water, thus providing better conditions for subsequent filtration or precipitation steps.
4. Water Stirring: The operation of the disc diffuser promotes a slight stirring of the water column, which helps prevent the formation of localized dead zones in seawater. Dead zones can lead to retention of substances in the water, thus reducing the efficiency of subsequent treatment steps.The Recirculating Polygeyser
