Diffuser disc is a device used in aeration systems usually is connected with blowers to disperse air oxygen into water, help the oxygenation process much better. People widely use it in applications like aquaculture, wastewater treatment, and pond aeration. The diffuser disc plays essential role in aeration system that helps in distributing fine air bubbles throughout the water, which increases the water's dissolved oxygen.
Material: Diffuser discs are made from EPDM (Ethylene Propylene Diene Monomer), Silicone rubber. These materials ensure durability and the ability to withstand chemical substances, abrasion, and ultraviolet radiation.
Porosity: The diffuser disc's surface is manufactured with micro-pores pores. These tiny pores release fine air bubbles into the water. The production of such fine bubbles is crucial as it maximizes the efficiency of oxygen transfer between the air and the water.
Size and Configuration: Diffuser discs are available in a wide range of sizes, range from small to large diameters. Their design also permits them to be configured to work effectively in both shallow and deep water setups. The flexibility in size and configuration make them can be used in various water bodies and systems.
Bubble Size Control: Diffuser discs possess the capacity to generate either fine or coarse bubbles. The selection between these two types of bubbles is determined by the specific purpose of their use and the degree of oxygenation that is needed. For instance, in applications where a high rate of oxygen transfer is required, fine bubbles are often preferred.
