Methane fermentation wastewater treatment is a method of wastewater treatment that utilizes microorganisms (anaerobic bacteria) that thrive in environments with little to no oxygen. Since aeration, which supplies air to the treatment tank, is unnecessary, it can significantly reduce power consumption. Additionally, this process converts the pollutants (organic matter) in the wastewater into methane gas. The generated methane gas has the same components as city gas and can be used as fuel for boilers and generators, thereby reducing the use of conventional fuels (fossil fuels). Furthermore, due to the slow growth of the microorganisms, the amount of excess sludge generated is also low, allowing for simultaneous waste reduction. These features not only reduce the running costs associated with wastewater treatment but also contribute to CO2 reduction. The reduction of fuel corresponds to Scope 1, the reduction of electricity corresponds to Scope 2, and the reduction of waste corresponds to Scope 3, making it a rapidly spreading technology for achieving decarbonization in factories. We will be exhibiting at the 5th Food Tech Japan Tokyo (to be held from November 20 to 22, 2024, at Makuhari Messe) at booth 2 Hall 7-54. We will also be showcasing this product, so please come and visit us.

Free membership registrationIn conventional wastewater biological treatment (such as activated sludge method), treatment is carried out by utilizing oxygen supplied by blowers, where microorganisms oxidize and decompose pollutants in water into water and carbon dioxide (aerobic treatment). In contrast, anaerobic treatment (methane fermentation) is a method that converts pollutants primarily into methane gas through the action of anaerobic (oxygen-unfriendly) microorganisms under oxygen-deprived conditions. It has recently gained attention due to the various advantages it offers that are not present in aerobic treatment. 【Features】 - Recovery of methane gas from wastewater, contributing to CO2 reduction with low energy consumption. - Sludge generation is 1/5 to 1/10 of that in aerobic treatment. - In the case of sewage discharge, sufficient water quality can be achieved with "UASB-TLP" alone. - High-load operation with CODcr load of 40-50 kg/m³ per day is possible. For more details, please contact us or download the catalog.

Free membership registrationThe "Rotating Child Raia" is a fixed bed (contact aeration type) wastewater treatment device. It fills the tank with a carrier that retains microorganisms, purifying the water quality through the activity of microorganisms on the carrier's surface. There is no need to manage sludge concentration like in the activated sludge method, and there is no return sludge. Strict management of dissolved oxygen concentration is also unnecessary, allowing for stable operation without specialized knowledge. Thanks to the high-performance carrier with a large surface area and a continuous cleaning mechanism, it completely prevents the major drawback of fixed beds, which is tank clogging, enabling high-load operation of 5 to 15 kg-BOD/m³·D. 【Features】 ○ Enhancement of existing equipment capacity ○ Reduction of running costs ○ Easy operation management For more details, please contact us or download the catalog.

Free membership registrationThe solid-liquid separation of the "Super Pressurized Floating Device SUPER-DAF" uses a technology that attaches fine bubbles to particles in water, allowing for their flotation and removal. It is widely used alongside sedimentation methods for the removal of suspended solids (SS). The rapid separation speed of particles results in a compact device, and the high concentration of the resulting sludge makes subsequent treatments, such as dewatering, easier. 【Features】 ○ Achieves over 20 times the solid-liquid separation speed compared to sedimentation methods ○ The device is extremely compact ○ Very little outflow of SS ○ Produces high-quality treated water For more details, please contact us or download the catalog.
