Various aerated diffusers
The aeration types used to treat sewage in sewage treatment units are divided into two broad categories of porous and non-porous spreaders. The most common type of player is the player’s plates, domes, discs and tubes. The diaphragm panel is placed on concrete or aluminum foundations, and each frame can have 6 or more plates. Each base group is connected to the air pipe at appropriate intervals throughout the reservoir and controlled by the valve.
Different types of diffusers in terms of manufacturing bubbles
The diffusers are classified into three types of fine bubbles, medium bubbles and coarse bubbles in terms of production bubbles. The small bubble diffusers, due to their small size and the higher production bubbles, have a higher contact surface with sewage and have higher oxygen transfer capacity to organic sewage. Coarse bubble diffusers create a stream of uniformity in the sewage.
Various kinds of porous diffusers:
- Page: air Transfer Efficiency There are many types of diffusers that are shaped like square plates mounted on fixed supports in the bottom of the tank.
- Dome: air Transfer Efficiency There are many types of diffusers that are installed close to the tank floor on air distribution pipes.
- Disc: rigid ceramic discs or flexible fluid movements are installed close to the bottom of the tank on air pipes.
- piepd: tubular shaped runners made of rigid or soft plastic ceramics or synthetic rubber parts are installed on air distribution tubes.
in the aeration section, the sewage is selected according to the design parameters as well as the quality of the wastewater and the amount of air required for the aeration blender type. Then, depending on the amount of air injected into the sewage, the type and number of diffusers are specified. For smoothing and milling sections, large bubble diffusers are used.
In the manufacture of various aeration diffusers, various materials are used such as ceramics, rigid plastics, flexible plastics and rubber sheeting, plastic or flexible fabric. Ceramic materials consist of particles of unidimensional, bullet-shaped, or irregularly shaped minerals that provide a network of interconnected pores for compressed air flow.
the air forms, when passing through the surface holes, depending on the size of the hole, the surface tension, the air passage of the air bubbles of a given size. Plastics, like ceramics, have cavities that have compressed air from inside them, thin pillows and flexible plastic or synthetic rubber are also invented that can be used with discus and tube.
