Nitrogen management in wastewater industry from circular economy perspective

The municipal wastewater industry is known as a resourceful hub as it contains large amount of valuable nitrogen that can be recovered. However, the operation of conventional nitrogen management in the municipal wastewater industry is by nitrogen removal, mainly through biological nitrogen removal (...
