It might be done in crops utilizing mechanized remedy units much like All those useful for industrial wastewater. Where by land is available for ponds, settling basins and facultative lagoons may have lower operational costs for seasonal use circumstances from breeding or harvest cycles.[13]: six–8 Animal slurries are frequently taken care of by containment in anaerobic lagoons ahead of disposal by spray or trickle software to grassland.

Differing types of screens, which include coarse screens, fantastic screens, and micro screens, are made use of determined by the scale on the particles to be taken off. The removed solids will often be sent to landfills or even more processed for reuse, depending on their composition.
