Secondary treatment is extensively used in sewage treatment and can also be relevant to lots of agricultural and industrial wastewaters.
Therefore, land disposal and subsurface disposal of sewage started to get amplified focus where by feasible. These kinds of “small-tech” air pollution Management methods not just may well enable to preserve Electrical power but also may possibly serve to recycle nutrients and replenish groundwater provides.
