Possible applications

JTOP Co., Ltd. is a manufacturer of on-site regenerating activated carbon devices that do not require replacement of activated carbon.
There is a possibility that the dyed drainage can be treated to be colorless and transparent. The treated water can be reused as washing water in the manufacturing process. (Drainage recycling technology, system that does not discharge drainage into the river)
Our company has already sold and delivered as a wastewater recycling equipment that purifies and processes dyed wastewater discharged from textile factories to colorless and odorless water, through the JICA project in Indonesia. We have experience of SDGs business there.

Competitive advantage

Comparison with the conventional method
The conventional method picks up used activated carbon from a tank and it is regenerated by using a kiln furnace which causes more than 30% weight reduction and 20% performance degradation, reflecting costs of activated carbon for replacement, waste transportation and waste treatment.
By contrast, our automatic reproduction technology is able to regenerate saturated activated carbon by superheated steam without taking out the active carbon from the equipment.

JTOP method is less than 0.1% weight reduction, less than 1% performance degradation. It is not necessary expense and waste logistics cost, also new activated carbon purchase cost.
This system is superior in its easier maintenance of performance.
In the conventional method, if it is necessary to replace the activated carbon four times a year with a 10m³ activated carbon, the cost for one year is about 10 million JPY, but in the case of JTOP on-site regeneration activated carbon system, the regeneration cost can be annually less than 200,000 JPY.
Compared to the conventional method, the running cost is about less than 1/50.

Performance

JTOP Co.,Ltd. has installed the active carbon filtration devices with the regeneration system to wastewater treatment plants, for various applications (see Fig. 3 and 4).

In addition, filtration performance (adsorption rate) of the activated carbon does not change throughout of the 10 times cycle (see table 1), as well as physical and chemical properties (see table 2).

Technical maturity / Past record of introduction

1) Domestic sales of machines: 79
Application: wastewater treatment in a manufacturer of automobile parts, Chemical plant, warm bath facility

2) Overseas sales of machines: 9
・China 4
・Taiwan 2
・Indonesia 2
・Bangladesh 1
Application: wastewater treatment in a textile mill (Indonesia, Bangladesh), Chemical plant (China, Taiwan)

From now on, we are examining and promoting the same drainage recycling business as Indonesia through the JICA project in Bangladesh. In March 2019, we visited two local fiber manufacturers in Bangladesh, confirming that there was a large need for wastewater treatment from local companies.

We also visited the Ministry of the Environment (MOE), the Dhaka Water Supply & Sewerage Authority (DWASA), the Bangladesh University of Eng and Tech (BUET), a local water treatment engineering company, etc. with local JICA staff. We confirmed the magnitude of needs for local development issues and drainage measures.
