A wastewater treatment device that can significantly reduce power consumption. It can enhance capacity at minimal cost while utilizing existing equipment.

**Product Description** The AT-BC device rotates several gourd-shaped contact bodies with a thickness of 50mm and a diameter of 2000mm to come into contact with wastewater, allowing the microorganisms that adhere to them to remove 60-70% of BOD and other substances. By installing it in the front section of the aeration tank, it significantly reduces the BOD load, resulting in a smaller aeration tank in the later stage. Additionally, since less air is required for the aeration tank, power costs can be greatly reduced. The amount of excess sludge is also less than half compared to conventional methods. It is ideal not only for new installations but also for expansions and modifications; simply adding the AT-BC device in front of the aeration tank can more than double the capacity of the aeration tank, and there is no need to increase the number of blowers for the aeration tank. It can be placed on top of existing tanks, so no new space is required. Moreover, it allows for easy capacity upgrades without stopping existing equipment.

Significantly improve wastewater treatment capacity at low cost! It can be expanded without stopping the wastewater treatment facility, and even with more than double the treatment capacity, the electricity costs remain the same! New installations are also supported.
