SSI Retrievable Aerator - One to Four - Cross Type

  The 1-to-4 cross-type retrievable aeration disc is an important part of Shanghai Dubhe Environmental Protection's retrievable aeration system. It adopts a cross-shaped layout, with a single unit integrating 4 aeration discs, which is compatible with the system through connection methods such as QTS saddle. Its core design is a retrievable structure, using the branch air riser as a lifting device, which allows the aeration unit to be directly lifted out of the water without draining the tank, facilitating thorough cleaning, maintenance and replacement, and ensuring that the aeration system is always in optimal operating condition. All underwater components are made of stainless steel supports, which are highly durable and can stably meet the aeration needs of wastewater treatment scenarios for a long time.

1. No shutdown for maintenance：No need to drain water or stop operation during inspection or replacement, avoiding economic losses caused by shutdown and ensuring continuous wastewater treatment.

2. Easy installation：The installation process is simple, and it can be directly added to the existing fixed aeration system at the bottom of the tank without removing old equipment, greatly shortening the construction period.

3. Convenient maintenance：The aeration unit can be lifted out of the tank as a whole for maintenance operations, without affecting the normal operation of other wastewater treatment units in the tank.

4. Long service life：The underwater components adopt stainless steel supports, which have excellent corrosion resistance, adapt to complex sewage environments and prolong the service life of the equipment.

  It is suitable for new, retrofitted and standard-upgraded wastewater treatment projects, and is widely used in municipal wastewater treatment, industrial wastewater treatment and other scenarios. It is especially suitable for projects that require frequent replacement or maintenance of aerators, which can effectively improve the operation and maintenance efficiency and stability of wastewater treatment systems.
