What is a bubble diffuser?

Bubble diffuser is a device that uses bubble mass to aerate the sewage water to help in the production of beneficial bacterial enzymes. These enzymes help break down waste solids in water that facilitate filtering or clarification. Bubble diffusers usually consist of pipes, boards or discs perforated by a large number of regularly placed holes. The air is pumped over the head of the diffuser, generating bubbles that facilitate the process. The size of the bubbles plays an important role in the efficiency of the bubble diffuser. This allows effective removal of solids and the highest quality of secondary waste water or drain water. One of the best ways to achieve this is to allow bacterial enzymes to naturally decompose material. The healthy spread of these enzymes relies on the source of food and the abundant oxygen source. Suspended solids supply the source of food, while aeration of water ensures the corresponding oxygen supply.

Waste waters are a significant percentage of energy use of any treatment plant. This is especially true for plants that use aeration methods such as mechanical agitators. The bubble diffuser offers low maintenance and cost -effective possibility for oxygen infusion. These mechanisms usually have only the heads of the diffuser submerged in waste water; The air pumps located above the water create simple maintenance of the system. The lack of submerged moving parts also causes lower running and maintenance costs.

The diffuser of the bubble consists of a submerged diffuser head located on the floor of the separation tank. The diffuser heads can be made of tubular, flat plate, disk or dome. The head is perforated by a regularly distributed formula of HSKRze which is drawn from the surface compressed air. The resulting mass of bubbles slowly rises over the waste water and fills it with oxygen. This oxygenation then creates a suitable environment for the production of bacterialCh enzymes.

The size of the bubbles is an important variable in the effectiveness of the diffuser system of the bubbles. In the past, relatively coarse diffuser holes were used; It was assumed that the larger size of the bubbles ensured a faster increase in increase and better "drawing" or distribution of oxygen. Current trends tend to use smaller holes because the research has shown that a finer bubble mass is more effective in oxygenation in most applications. The average size of the diffuser opening in most of the waste water plants is approximately 0.08 inches or 2 mm with a small size as small as 0.04 inches or 0.9 mm used in some cases.
