On the morning of December 8, Ho Chi Minh City was covered by a thick haze that significantly reduced visibility. Roads appeared gloomy, sunlight was weak, and buildings were obscured across many districts. According to experts, this was a mixed haze consisting of both fog and airborne pollutants such as smoke and dust, which can seriously affect public health .
Fine dust pollution has become one of the most serious environmental challenges in modern cities, affecting both quality of life and long-term urban sustainability.
Fine dust – a global issue
Air pollution has become a major global concern. The cost of polluted air is extremely high for every country, as it affects economic development, living standards, and public health. It contributes to chronic disease and even premature death.
Every year, around three million people worldwide die from outdoor air pollution. According to the World Health Organization, more than 80% of people living in urban areas are exposed to air quality levels that exceed recommended limits. In many countries, the reality may be even worse because air monitoring systems remain incomplete or inconsistent.
The current air pollution situation in Vietnam
In Vietnam’s urban areas, the main sources of air pollution are transportation, industrial emissions, and daily residential activities. In Ho Chi Minh City alone, there are more than 9 million vehicles in circulation, including over 600,000 cars and nearly 7.5 million motorbikes.
Air monitoring data has shown that levels of PM10 and PM2.5 in the city often exceed permitted standards. In addition, other indicators such as total suspended particles, nitrogen dioxide, and urban noise also fail to meet environmental requirements.
Fine dust pollution in Ho Chi Minh City
Traffic activity accounts for the vast majority of carbon monoxide emissions in Ho Chi Minh City, with motorcycles contributing the largest share. Carbon monoxide is highly toxic, and excessive exposure may lead to oxygen deficiency, neurological damage, or even death.
Fine dust pollution is also strongly linked to rapid urbanization. Alongside urban growth comes the expansion of construction, logistics, transport, and manufacturing. Dust from building sites, industrial workshops, and vehicle exhaust becomes a constant source of urban air contamination.
In some cases, even modern street cleaning methods are not fully optimized. Certain road sweepers may release dust back into the air during operation, which worsens pollution instead of reducing it.
Dulevo urban sweepers – a long-term and comprehensive solution for fine dust control
1. Collection of both large debris and fine dust
Dulevo urban sweepers represent a major improvement in street cleaning technology. They combine:
-
70% mechanical sweeping with conveyor collection
-
30% vacuum suction technology
This combination allows the machine to collect both large waste and fine airborne particles efficiently in a compact design.
Mechanical sweeping technology helps collect larger debris, including heavier waste that many vacuum-only sweepers cannot handle. At the same time, vacuum sweeping technology allows the system to capture fine dust particles effectively.
2. Powerful filtration system to prevent secondary pollution
One of the most important concerns in urban cleaning is preventing dust from being re-released into the environment. Dulevo sweepers are equipped with advanced dust filtration systems similar to industrial vacuum cleaners.
Standard Dulevo filtration systems can capture up to 99.9% of fine particles down to PM10, with strong performance even for PM2.5. For more demanding industries such as cement or oil and gas, Dulevo also offers an exclusive Gore-Tex filtration option capable of collecting particles as small as PM1.
This ensures that air released from the machine remains clean and does not contribute to secondary pollution.
3. Single-engine design for lower emissions and fuel use
Dulevo urban sweepers are designed with a single powerful diesel engine that can operate continuously for 8 to 16 hours per day, seven days a week.
Because the machine only uses one engine, it consumes less fuel than many competing models that require at least two engines. This design also helps reduce exhaust emissions significantly, supporting greener and more sustainable urban cleaning operations.
Conclusion
Controlling fine dust pollution in urban areas requires coordinated action from authorities, operators, and technology providers. Street sweepers alone cannot solve the entire problem, but they are an important part of a broader environmental strategy.
With advanced sweeping technology, high-performance filtration, and reduced emissions, Dulevo urban sweepers provide a long-term and comprehensive solution for managing fine dust in cities more effectively.
