These substances can pass through the treatment process and enter aquatic ecosystems, [33] which creates a challenge for water treatment technology and emphasizes the need for ongoing research and infrastructure improvement to address the removal of CEC from wastewater. Advances like tertiary treatment stages, which incorporate advanced ...
Polishing is also an example. The main by-product from wastewater treatment plants is a type of sludge that is usually treated in the same or another wastewater treatment plant. [2]: Ch.14 Biogas can be another by-product if the process uses anaerobic treatment. Treated wastewater can be reused as reclaimed water. [3]
