Biological wastewater treatment: comparative method / Nurul Syairah Mohd Fadzil

Water is a natural resource that is essential for all living things. However, owing to the growth of the human population and eco-unfriendly practices, fresh water has been enormously polluted over the past century and form a low-quality water called wastewater. As mentioned, wastewater may come fro...

However, owing to the growth of the human population and eco-unfriendly practices, fresh water has been enormously polluted over the past century and form a low-quality water called wastewater.
