As usual no reply from Mr.Cyril till now. I don't think they are in a position to cover up their faults. But I need 2 documents from Plworldways as asked vide my earlier mail to take up the matter with embassy and compensation from LVT on the work done by me so far. I am confident that you will get rid of yr problems encountered with the bag filters for both the projects if you implement the modufications as per my study reports. Better try my suggestions....
