A "Main procedure" move generally precedes secondary remedy, whereby physical phase separation is made use of to get rid of settleable solids. In the course of secondary therapy, biological processes are used to get rid of dissolved and suspended natural issue calculated as biochemical oxygen need (BOD).
It could be done in vegetation using mechanized therapy units similar to Those people useful for industrial wastewater. Where by land is available for ponds, settling basins and facultative lagoons may have decreased operational fees for seasonal use disorders from breeding or harvest cycles.[13]: 6–8 Animal slurries are frequently treated by containment in anaerobic lagoons prior to disposal by spray or trickle application to grassland.
