Paddle-Type Fine Bubble Diffuser
A paddle-shaped fine bubble diffuser designed to provide uniform oxygen transfer and reliable aeration for biological wastewater treatment systems.
A paddle-shaped fine bubble diffuser designed to provide uniform oxygen transfer and reliable aeration for biological wastewater treatment systems.
Product Overview
The Paddle-Type Fine Bubble Diffuser is a submerged microporous aeration device installed on the air distribution piping at the bottom of an aeration tank.
Compressed air supplied by an external blower enters the flat-oval support tube and passes through the perforated membrane, forming fine bubbles in the wastewater. As the bubbles rise, oxygen is transferred into the water to support aerobic microorganisms and biological treatment.
Its paddle-shaped profile provides a broad aeration surface while retaining the convenient installation structure of a tube diffuser. It is a stationary fine bubble diffuser rather than a mechanically driven paddlewheel aerator.
The diffuser can be configured in fixed-bottom or liftable aeration systems according to the tank structure and maintenance requirements.
Process Flow:
Air Blower → Main Air Pipe → Air Distribution Pipe → Paddle-Type Fine Bubble Diffuser → Fine Bubble Release → Oxygen Transfer → Biological Treatment
This product is a professional sewage treatment solution developed for [target sewage types such as municipal domestic sewage/industrial organic wastewater/breeding wastewater/medical wastewater]. Integrating [core technologies such as biological treatment/membrane separation/advanced oxidation/intelligent control], it can efficiently remove pollutants including COD, BOD, ammonia nitrogen, total phosphorus, suspended solids, and toxic and harmful substances from sewage. With core advantages of [small footprint/low operating cost/high treatment efficiency/easy operation and maintenance], the product is widely applicable to [application scenarios such as urban communities, industrial parks, livestock and poultry farms, medical institutions, scenic spots]. The treated effluent can meet [specific standards such as GB18918-2002 Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (Grade 1A) / local customized discharge standards], realizing harmless discharge or resource recycling of sewage
Core Advantages
- Uniform Fine Bubble Aeration: The flat paddle-shaped membrane surface helps distribute fine bubbles evenly across the aeration area.
- Flat-Oval Support Structure: The support tube combines a broad aeration surface with the installation convenience of a tube diffuser.
- Continued Aeration After Local Membrane Damage: The internal support-tube structure helps maintain air distribution if a local section of the membrane is damaged, reducing the impact on the overall aeration system.
- Condensate Drainage Design: The structural design helps accumulated condensate drain from the aeration piping and supports stable airflow.
- Multiple Membrane Options: PU, EPDM and silicone membranes can be selected according to wastewater characteristics and operating conditions.
- Flexible Installation: Suitable for fixed-bottom, liftable and retrofit aeration system configurations.
- Efficient Purification & Compliance Assurance
Adopting [core technology name], it can rapidly decompose complex pollutants in sewage with a pollutant removal rate of up to [specific percentage, e.g., over 95%], ensuring stable compliance of effluent quality and strong adaptability to fluctuations in water quality. - Energy Conservation, Environmental Protection & Cost Control
Designed in line with energy-saving concepts, the equipment/agent [e.g., uses low-power motors/zero chemical addition with biological strains/circulating treatment process], significantly reducing energy consumption and chemical costs during operation. It also minimizes sludge production and lowers solid waste disposal expenses. - Flexible Adaptation & Easy Installation
To meet diverse scenario requirements, it offers [modular assembly/mobile deployment/customized configuration] solutions, occupying only [specific ratio, e.g., 60%] of the area of traditional processes. Whether for new projects or renovation of old facilities, installation and commissioning can be completed quickly. - Intelligent Management & Hassle-Free Operation
Equipped with [intelligent sensors/Internet of Things (IoT) monitoring platform/automatic dosing system], it can real-time monitor water quality indicators and equipment operating status, supporting remote control and fault early warning. No on-site personnel are required, reducing the threshold for manual operation and maintenance. - Green Sustainability & Resource Recycling
The treated effluent can be used for [farmland irrigation/landscaping irrigation/industrial cooling water/municipal miscellaneous use] as needed, realizing water resource recycling. Sludge can be converted into [organic fertilizer raw materials/biomass fuel] after further treatment, aligning with green development concepts.
