Joint research between the Japan Sewage Works Agency and Toshiba at the sewage treatment plant in Sakura City, Tochigi Prefecture.

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.

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.

【Expansion】 The issues of "insufficient capacity of treatment facilities" and "difficulty in expansion due to lack of installation space" can be resolved in one go by simply placing the AT-BC device on top of the existing tank! It significantly enhances wastewater treatment capacity at a low cost. This is a wastewater treatment system that evolves two treatment methods: the activated sludge method and the rotating biological contactor method. 【Features】 ■ Expansion possible without stopping wastewater ■ Construction period is about 2 weeks ■ Capacity more than doubles just by placing the AT device on the existing tank ■ Capital investment costs can be about 2/3 ■ Even with more than double the treatment capacity, electricity costs remain unchanged ■ Excess sludge is reduced to less than half ■ Suitable for nitrogen and phosphorus removal and deodorization effects 【New Installation】 This is a wastewater treatment system that evolves the activated sludge method and the rotating biological contactor method, efficiently removing BOD, COD, SS, N-Hex, T-N, T-P, etc., by proliferating Bacillus bacteria in the AT-BC device (three-dimensional rotating device) and aeration tank, and furthermore, it is a groundbreaking system that also eliminates unpleasant odors. 【Features】 ■ Installation area is about 2/3 ■ Power consumption is about 2/3 ■ Excess sludge is about 2/3 ■ Odor is significantly reduced ■ Suitable for nitrogen and phosphorus removal and deodorization effects *For details, please request materials or view the PDF data from the download.

The "Mechanical Stitch Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
