A wastewater treatment device that recovers methane gas from wastewater (creating energy), requires little power (saving energy), and generates a small amount of sludge. It achieves decarbonization.
In 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.

basic information
**Principle of High Performance** ○ Turbulent → Raw water with high BOD concentration flows in, generating a large amount of gas through methane fermentation. → Gas lift creates a vertical circulation flow, stirring the tank and promoting reactions. ○ Laminar → In the upper laminar zone, the BOD concentration of the raw water decreases, and gas generation reduces. → Vertical stirring weakens, resulting in clear treated water. ○ Pulsation → Intermittently supplying raw water creates pulsation in the lower part of the reactor. → Promotes reactions by efficiently contacting raw water with granules. ● For more details, please contact us or download the catalog.
