Testing Pipe Support Spacing

Aeration system pipe supports are typically spaced in the industry to provide long-term performance and service of aeration piping systems. In the spacing of these pipe supports, there are several variables that must be considered and evaluated to create a proper design. Clearly, there is a desire to have the pipe supports function properly while using the minimum number in order to control economics for the sys...

Retrievable Diffuser Aeration Systems

Below we evaluate retrievable diffuser systems by reviewing several common primary types of units. Simple drop-type assembly with a small diameter pipe and “T” section at the bottom. Diffusers are mounted at the “T” section and are installed near one wall of the aeration basin. This configuration creates a strong roll mix aeration pattern in the basin size fluid schematics shown in Figure 1.

Coarse Bubble Diffusers

Coarse Bubble Diffusers 103 Coarse bubble diffusers are suitable for almost any type of water and wastewater application. The primary application of coarse bubble diffuser systems today are as indicated below: Aerobic Digestion Applications Coarse bubble diffusers have been the traditional diffusers used in these applications. The standard design rate for this application is 30 scfm per 1000 ft of tank volume....

Fine Bubble Aeration

Fine bubble aeration systems are inherently more efficient in oxygen transfer than coarse bubble aeration systems. Overall, a fine bubble aeration system configured in a grid configuration will operate at approximately 50% the energy consumption of coarse bubble systems. Because of this high operating efficiency and corresponding reduction in energy consumption, fine bubble aeration systems have been and continu...
