What are the cheapest wastewater treatment technologies?

There are many wastewater management technologies that are cheaper than traditional wastewater treatment, like biosolids on land applications. In terms of biological processes, screening is one of the most affordable options.

Membrane bioreactors and activated sludge treatments require a smaller area (an important factor in densely populated areas) and can then be appropriate alternatives for many municipalities that currently discharge untreated wastewater into surface waters.
