For urban applications the area requirement of a subsurface flow constructed wetland might be a limiting factor compared to conventional municipal wastewater treatment plants. High rate aerobic treatment processes like activated sludge plants, trickling filters, rotating discs, submerged aerated filters or membrane bioreactor plants require ...
A mechanised waste water plant opened in 1905 and five purification plants now filter the water before releasing it into the Rhine. [1] [3] By 1933 the length of the system measured 735 kilometres (457 mi), [3] and by 2011 it had expanded to 2,400 kilometres (1,500 mi). [4]
