Japan introduces advanced wastewater treatment technology
The International Exhibition on Wastewater Treatment Technology recently held in Tokyo introduced the latest achievements of Japanese enterprises in this highly interested field.
The exhibition was organized in cooperation between the Japan Business Association and 61 related companies, attracting the participation of 329 companies operating in the field of wastewater treatment and water works.
Wastewater treatment is an essential activity of society, helping to improve the living environment and water quality in the public water supply system. Not to mention that in recent years, urban areas have been frequently flooded and the trend of wastewater re-treatment has also increased.
Many modern wastewater treatment designs and models were introduced at the exhibition; in addition, construction technology, materials, equipment for installing wastewater channels and wastewater reservoirs; maintenance and measurement work, etc.
The exhibition not only introduces the most advanced solutions, but also focuses on bringing Japan's leading technologies abroad, focusing on customers such as local governments or companies specializing in wastewater treatment systems in localities around the world. Therefore, the organizers have organized many seminars for Japanese enterprises to share their experiences with foreign customers, including the Asia Session seminar, attracting visitors from Vietnam.
At the exhibition, PASCO proposed a wastewater management solution using geostationary information and information technology based on recent advances in Japan.
Pasco exhibited a survey vehicle called “Real Petit” equipped with a CCD camera and a GPS (Global Positioning System). It can survey up to 30km/day. PASCO also has a vehicle equipped with an MMS (Mobile Mapping System) system with multiple CCD and 3D laser measuring devices. The “Real Petit” can survey narrow streets that are difficult for other vehicles to access.
Thanks to these cutting-edge technologies, people can accurately check the condition of the drainage wells, effectively manage them through damage analysis, determine their location relative to the road surface based on the survey photos taken with GPS information. The collected data will be connected to a monitoring system installed on a tablet for field inspection engineers.
Another innovative technology introduced by PASCO is “Pas CAL” – a system to support the planning of wastewater systems. A lot of information related to wastewater sewers can be collected through linking with data maps. The damage and condition of wastewater sewers can be analyzed at 3 levels, depending on their deterioration trends.
Meanwhile, EBARA Corporation exhibited a variety of multi-purpose sewage pump trucks. These trucks were equipped with compact, high-capacity water pumping systems and were designed to be installed manually. EBARA also developed lightweight water pumps weighing only 20kg.
In addition, the group also introduced multi-purpose pump trucks, which can support many water-related disaster situations such as water system failure, localized flooding due to sudden heavy rain or widespread flooding due to prolonged rain, and even tsunami disasters.
EBARA's vacuum sewage pump systems are designed to be installed in water supply systems and pump systems located in difficult terrain, such as soft ground, rocky ground or water bodies located at high altitudes.
MGT is a small gas turbine that uses waste gas from wastewater systems such as methane. This turbine will generate electricity by burning methane gas. It helps improve environmental quality due to clean emissions, low noise and vibration during operation.
Currently, PASCO, EBARA as well as many other Japanese enterprises operating in the field of wastewater treatment have representative offices and even built factories in Vietnam. With the rapid development of industrial zones and urban areas, wastewater treatment is one of the key steps, aiming at the goal of sustainable development and environmental friendliness.
Japanese enterprises 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./.
