The demand for a new treatment technology has emerged because the current methods suffer from issues with energy-consumption and disposal limitations. Is WEF capable of providing technology to solve these two issues?

For sludge that has already been generated, our established technologies, such as of α-Gaia and CLIRAC treatment method can solve these issues. However, we believe it will be more important to focus on reducing the amount of sludge that is initially generated. We have dealt with many cases for reducing sludge volume, with our SBC-Pro rapid organic decomposition process, which adopts Japan’s latest technologies, such as our UFB (Ultra Fine Bubble) generator, SBC contact material, and in some cases, BFC bacteria.



In this system, organic matter is processed as much as possible prior to the activated sludge treatment process (biological treatment). Large volume processing of organic matter and oil substance is possible. By using a UFB generator, which supplies highly concentrated oxygen in very fine bubble form, large amounts of active microbes are produced to consume organic substances in the treatment water. Moreover, SBC contact material helps produce anaerobes as well, so sludge production is minimized by this process (anaerobes eat weaker aerobes). This also allows reduction of biological treatment tank size.

We have an actual case in a meat-processing factory where, using our system which doesn’t rely on a pressurized flotation separation process, no sludge removal was necessary for five consecutive years, and the processed water is discharged to waterways. Beginning in 2018, we will launch a collaborative research project on this system with a major environmental company in China at their sewage treatment facility.

Petroleum sludge is known to be very difficult to treat, therefore, such sludge is normally left untreated. Is your technology able to treat and recycle this type of sludge?
The demand for a new treatment technology has emerged because the current methods suffer from issues with energy-consumption and disposal limitations. Is WEF capable of providing technology to solve these two issues?
Pressurized flotation separation process of oil requires a large amount of chemicals in addition to high maintenance and cost for disposing the separated oil substance as industrial waste. Does the SBC-Pro treatment system help solve these issues?
Waste disposal is broadly categorized as one of two types, industrial waste or general waste. For general waste disposal, unlike Japan, China and other Asian countries are lacking strict waste recycling regulations, even though their landfill capacities are getting smaller and smaller. We often see photos of children in such countries working and searching for valuables in the waste disposal sites (raw garbage). Do you have any solution to treat general waste without waste segregation?
