In the
zootechnical sector, it is important to
treat wastewater that corresponds to manure (sewage and manure) from animal farms in addition to the digestate produced by anaerobic plants fed with plant biomass and sewage/manure for the production of energy or biomethane
The rules relating to the sector are aimed at protecting ground and surface water from pollution caused by nitrogen produced and used in agricultural activities.
In the Zootechnical sector, therefore, the Agricultural Companies aim at solving different needs:
- Reduction of nitrogen in zootechnical effluents (as required by the EC Nitrates Directive 91/676) to allow the correct spread on the land, in relation to the available surfaces. It is also important to identify economically sustainable solutions through the analysis of a specific treatment chain for the needs of each individual case.
- Use of water intended for livestock with specific characteristics from a qualitative point of view
