Today’s challenge for efficient road and area cleaning and to curb city air pollution:
Road traffic permanently generates fine but hazardous particles (PM10 & PM2,5) deteriorating city air quality, causing health problems world-wide.
Dust and fine particles are also a major problem in many industrial sites (ports, industries, mines etc.), causing health and safety problems.
Traditional road sweeping is efficient to take away waste and debris, but normally
generates dust swirling around brushes and into the outgoing air from the machine
removes little of the hazardous fine dust & particles
As water or liquid often is sprinkled to prevent dust from swirling into the air when brushing,
the finest dust stay on the ground as a slurry – the particles stay on the surfaces and start to swirl up in the air once the water has dried up
some of the hazardous dust and particles are flushed down the water drains into sewage or water ways, sending the problem down-stream
