Wastewater treatment device AT-BC device (special mesh rotary biological contact device)

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

**Device Overview** The core of the AT-BC system, the AT-BC device, was developed from an improved rotating body of the rotating disk method, which is a type of activated sludge. The rotating body, which serves as the heart of the rotating disk, had a structural flaw where the metal parts would corrode rapidly when immersed in wastewater for extended periods. Additionally, it also had the drawback of microorganisms adhering to the rotating body detaching all at once, leading to a decrease in processing capacity. To address these shortcomings of the rotating body, the AT-BC device was developed. The rotating body of the AT-BC device features a three-dimensional mesh structure made from a vinylidene chloride fiber, the same material used in Asahi Kasei's Saran Wrap, processed into a gourd shape. This design successfully eliminated the metal parts that cause corrosion from the rotating body. Furthermore, by allowing microorganisms to adhere within the three-dimensional mesh structure, it has become possible to prevent the simultaneous detachment of microorganisms.
