Technologies in Sewage Treatment: Activated Sludge Process (ASP) & Conventional Type
An Activated Sludge Process (ASP) system commonly includes an aeration tank and a secondary clarifier. The first is used for biological degradation and the other is used to separate sludge from
Survey Through LIDAR Technology Using UAV (Drones)
Survey of India is established in 1767 which is 252 years ago. In this long period survey has achieved advance technology. In the initial period dumpy levels, theodolites and chain were used. Dedication and hard work surveyors and engineers have achieved a lot through these instruments. Pune-Mumbai Railway line has several tunnels and these are completed with survey instruments like theodolite and dumpy levels. Over period of time, technology evolved to find out distometer launched on theodolite and auto level. It was joyful for engineers and surveyors to complete survey work without tape. Further to that total station instrument and digital level made atomization in the instrument. For global location DGPS (Differential Global Positioning System) was used. DGPS : Differential Global Positioning Systems (DGPS) are enhancements to the Global Positioning System(GPS) which provide improved location accuracy, in the range of operations of each system, from the 15-meter nominal GPS accuracy to about 10 cm in case of the best implementations. The DGPS Survey main features are: ● Position is determined by distance from at least 4 satellites. ● Time taken by signal to travel from satellite to antenna used to determine the distance. ●
