Japan introduces advanced wastewater treatment technology.
The International Exhibition on Wastewater Treatment Technology, recently held in Tokyo, showcased the latest achievements of Japanese companies in this highly sought-after field.
The exhibition was organized in collaboration between the Japan Business Association and 61 related companies, attracting the participation of 329 companies operating in the wastewater treatment and water engineering sectors.
Wastewater treatment is an essential societal activity, helping to improve the living environment and water quality in public water supply systems. Not to mention that in recent years, urban areas have experienced frequent flooding, and the trend of wastewater reprocessing is also increasing.
Many modern wastewater treatment designs and models were showcased at the exhibition; alongside them were technologies for constructing, materials, and equipment for installing wastewater channels and reservoirs; and aspects of maintenance and measurement.
The exhibition not only showcased the most advanced solutions but also focused on bringing leading Japanese technologies to the international market, targeting local governments and wastewater treatment companies worldwide. Therefore, the organizers held numerous seminars where Japanese companies shared their experiences with foreign customers, including the Asia Session, which attracted attendees from Vietnam.
At the exhibition, PASCO proposed a wastewater management solution using geostationary information and information technology, based on recent advancements in Japan.
Pasco showcased its survey vehicle, named “Real Petit,” equipped with a CCD camera and a GPS (Global Positioning System). It can conduct surveys up to 30 km per day. PASCO also has vehicles equipped with an MMS (Mobile Mapping System) with multiple CCD and 3D laser-based measuring devices. The “Real Petit” vehicle can conduct surveys on narrow streets that are difficult for other vehicles to access.
Thanks to these cutting-edge technologies, it is possible to accurately assess the condition of sewage wells and manage them effectively by analyzing damage and determining their location relative to the road surface based on survey photos accompanied by GPS information. The data obtained is connected to a monitoring system installed on tablets used by engineers conducting field inspections.
Another advanced technology introduced by PASCO is “Pas CAL” – a wastewater system planning support system. Much information related to wastewater sewers can be collected through linking to data maps. Damage and the condition of wastewater sewers can be analyzed at three levels, depending on their deterioration trends.
Meanwhile, EBARA Corporation showcased several multi-purpose wastewater pumping vehicles. These vehicles were equipped with compact, high-capacity pumping systems designed for manual installation. EBARA also developed lightweight water pumps, weighing only 20kg.
In addition, the corporation also introduced multi-purpose pump trucks, designed to assist in various water-related disaster situations such as damaged water supply systems, localized flooding due to sudden heavy rains or widespread flooding due to prolonged rainfall, and even tsunamis.
EBARA's vacuum wastewater pump system is designed for installation in water supply and pumping systems located in challenging terrains, such as soft ground, rocky areas, or areas with water at high elevations.
MGT is a small gas turbine that utilizes effluent from wastewater systems, such as methane. This turbine generates electricity by burning methane gas. It helps improve environmental quality due to its clean emissions and low noise and vibration during operation.
Currently, PASCO, EBARA, and many other Japanese companies operating in the wastewater treatment sector have representative offices, and some have even built factories in Vietnam. With the rapid development of industrial zones and urban areas, wastewater treatment is a key factor in achieving sustainable and environmentally friendly development.
Japanese businesses are committed to bringing the most advanced solutions and technologies to Vietnam, not only to contribute to economic development but also to improve the quality of life for the community.
