India Ganga River Project

Summary:

1. CPB gave approval for OSE II and requested a proposal for the scope of work as well as cost.
2. Trip to Varanasi was very helpful to determine who to handle solids, as well as where to take samples for baseline information as well as where to dose OSE II.
3. The trip revealed there will need to be a mechanism to mix OSE II with the large volume of water, and to inject aeration as well. O2 depletion was obvious from the green color of the water depicting eutrophication to some extent. The drains are not anaerobic, since algae blooms in the flowing drains was marginal.
4. The drains showed varying widths across, therefore OSE II injection will need to be through stabilized perforated PVC pipes across the width of the drain will be required to inject OSE II evenly across each body of flowing liquid. The injection point will need to be at the midpoint of the water column from the surface of the liquid, and from the bed of the flowing liquid.
5. Aeration will need to be placed in two locations if possible at the site of injection of OSE II, and 30 meters below or towards the Ganaga River down gradient from the first aeration injection.
6. Aeration injection through stabilized large perforated PVC pipes across the width of the drain will need to be at the midpoint of the water column from the surface of the liquid, and from the bed of the flowing liquid.
7. There will need to be a mixing pump to stir the entire area of liquid where the OSE II injection will occur to insure as much saturation of the liquid molecules with OSE II as possible.
8. Electrical power to operate OSE II injection, aeration and the mixing pump will need to be sourced and secured as well, may require generators.
