(a) Yes Sir. The performance of Wind Augmentation Purifying Unit (WAYU) is evaluated for PM10 and PM2.5 monitoring at inlet and outlet of the device in the field. It is observed that device removes PM10 and PM2.5 by 28-49% and 9-25% respectively depending on amount of pollution load and device location. The device has potential applicability for limited area cleaning such as traffic intersections.
(b) Currently, there are no plans to have more WAYU units.
(c) Does not arise.
