What are the suitable technique and material for the control of ambient air fine dust particles and gases.
Any one help me.
Dear Navneet Kumar,
Some kind of dust collection system to control particulate emissions.[These systems include
1. Inertial collectors (cyclonic separators),
2. fabric filter collectors (bag houses),
3. Wet scrubbers, and electrostatic precipitators.
Cyclonic separators are useful for removing large, coarse particles and are often employed as a first step or "pre-cleaner" to other more efficient collectors. Well-designed cyclonic separators can be very efficient in removing even fine particulates, and may be operated continuously without requiring frequent shutdowns for maintenance.
Fabric filters bughouses are the most commonly employed in general industry.[They work by forcing dust laden air through a bag shaped fabric filter leaving the particulate to collect on the outer surface of the bag and allowing the now clean air to pass through to either be exhausted into the atmosphere or in some cases recirculated into the facility. Common fabrics include polyester and fiberglass and common fabric coatings include PTF (commonly known as Teflon). The excess dust build up is then cleaned from the bags and removed from the collector.
Wet scrubbers pass the dirty air through a scrubbing solution (usually a mixture of water and other compounds) allowing the particulate to attach to the liquid molecules. Electrostatic precipitators electrically charge the dirty air as it passes through. The now charged air then passes by large electrostatic plates which attract the charged particle in the airstream collecting them and leaving the now clean air to be exhausted or recirculated.First of all control the dust from source then contro by spraying the water on road as shown in the figure.

Thanks Sir for answer.
But, this system has industrial dust control. I have wanted ambient air (traffic intersection, residential area and commercial area) dust control.
Dear Navneet Kumar,
A vehicle-mounted dust collector was selected to monitor dust levels because of its ease of operation, ruggedness and consistent field measurements. The collector was attached to the rear bumper of a Dodge 1500 pickup. While the vehicle travelling down the road at 60 KM/hr, dust collected on a preweighed glass microfiber filter.
In Residential area
1. Vacuum cleaner to be used in residential area.
2. When planning the site layout,
3. Building location and earthworks you should take into account the following:
4. The soil erosion and drainage management plan.
5. The stabilized entry/exit point.

6. The location of stockpiles and storage materials.
7. The location of waste management facilities.
8. An area for brick cutting and concrete works.
9. A contained area for paint and plastering waste and wash waters a wash down area for vehicles and equipment . the location of noisy equipment so as to avoid annoying the neighbors.
Dear Prem Baboo Sir,
I have want the details of the DC Enclosure Control System. What are efficiency and Capacity of the blower. want the details of design system.
There different passive and active methods:
1-urban areas should be desinged to shift dust aerodynamically away as kind of adaptation, or
2-using green belts and naive plants as control measures
