1.What is an Membrane Disc Diffuser?
Membrane Disc Diffuser is an ideal addition to oxygenate and circulate the water in your pond or water garden. An air stone in the bottom of a pond will not add any oxygen into the pond until the bubbles reach the surface and break. As the bubbles float to the surface of the pond they bring along the water from the bottom of the pond which is usually low in oxygen. This creates a constant current of water moving from the bottom of the pond, where the oxygen level is low, to the surface where it can pick up oxygen.Membrane Disc Diffuser
Our Membrane Disc Diffuser are available in 9 inch or 12 inch diameter and are designed for the wastewater treatment industry to very high standards. The air pore size in the rubber membrane is designed to give a medium size bubble which will not put any significant back pressure on the system. In fact this special air disc only adds less than 6 inches of water depth back pressure. The 3/4" male thread makes it easy to attach to your feed line. The 9 inch disc is capable of handling air flows of 25lpm to 100 lpm. The 12 inch disc is capable of handling air flows up to 150 lpm.Membrane Disc Diffuser
The disc is very low maintenance and in some cases NO maintenance. Simply wash the disc with clean water and bleach if it ever needs cleaning. We have some of these air discs in systems now for over 3 years with out trouble or maintenance.
2.Some of the advantages of Disc Type Air Diffuser include the following:
-
Improved design: Because they are so slender, many Disc Type Air Diffuser can fit into a tank with a relatively modest footprint.
-
Increased mixing capabilities: Many tube diffusers tend to produce relatively large bubbles. The large bubbles often produced with tube diffusers offer superior mixing capabilities.
-
Lower cost: Tube diffusers are an excellent option for cost-conscious consumers. Reduced stainless steel use is a large part of the reason - stainless steel is expensive, whereas plastic and rubber are more economical.
-
Neutral buoyancy: Tube diffusers are neutrally buoyant. This characteristic gives them an advantage in certain aerator layouts.
-
The fine bubble air diffuser spreads bubbles over the entire surface of the membrane in order to increase air/liquid transfer and prevent any coalescence. It is mainly used for the aeration and oxygenation of activated sludge tanks in urban or industrial treatment plants.
