solid mass which can be easily separated later on.) Restoration of wetlands is one of the important means of treating sewage water. Wetlands allow to process sewage water naturally, without the use of any artificial method/technique. The idea behind restoring wetlands is that bacteria present in them would dilute the nitrates and phosphates. The same process takes place in sewage water treatment plants except that, here (in wetlands) it is carried out naturally.
Sewage treatment is the important thing, because 30 per cent of all pollution is comes from wastewater of sewages. It is very difficult to solve this problem in one day, we should spend a lot of time to find a solution by discovering and experiments. p align="justify"> pollution lake transboundary
