The activated sludge process is commonly used for organic treatment around the world. However, some highly-concentrated wastewater cannot be treated through an activated sludge process, which is reliant on microorganisms. If wastewater cannot be treated, it ends up being discharged into rivers and oceans, even though it is understood to be illegal. In order to solve these problems, we needed to consider new treatment methods. Our CM system is a processing method that focuses on the low molecular weight of enzymes. This system decomposes organic matter into cell membranes, cutting it like a pair of scissors, and eventually converting it into CO2 and water. This scientific process differs from microbial treatment in that it is less susceptible to concentrations, which makes it possible to treat even highly-concentrated wastewater. In addition to breaking down and deodorizing odors, the CM system can also reduce sludge by 70% to 90% by decomposing microorganisms that have died out in the system. Most of the sludge discharged from the CM system is inorganic and can be dried in the sun or reused. If sludge is not incinerated with fossil fuels, no CO2 will be produced. This is a new treatment method that can simultaneously solve the issue of water contamination and treatment issues that cities face, such as water contamination and odors.




We are now facing disruptive changes that we have never experienced before, such as global warming, a declining birthrate and aging population resulting in the decrease of the working population in Japan, the exponential progression of digitization. In the midst of these great changes, Nippon Steel Engineering Group is committed to seriously considering what we can do and what kind of value we can create as an integrated provider of engineering and construction solutions. In addition to the SDGs and COP 21 (the Paris Agreement), our mission shall be to build social and industrial infrastructures that are safe, secure and sustainable. As an engineering company with roots in steelmaking technology development, we will keep on delivering optimal solutions for our clients with our three strategic business sectors: Environment & Energy Solution, Building & Infrastructure and Plant & Machinery.
