Pretreated palm oil clinker as an attached growth media for organic matter removal from synthetic domestic wastewater in a sequencing batch reactor
Attached-growth systems are biological wastewater treatment processes with biomass attached to a media for organic matter and nutrient removal from wastewater. In this regard, bioreactors containing biocarriers have been successful by far with few limitations. The impact of bio-carrier materials typ...

Attached-growth systems are biological wastewater treatment processes with biomass attached to a media for organic matter and nutrient removal from wastewater. In this regard, bioreactors containing biocarriers have been successful by far with few limitations.
