Today, the livestock industry is considered to be one of the biggest emitters of ammonia in
the world. The nitrogen present in livestock manure has been linked to the contamination of …

Excessive livestock production in small areas poses a risk of nitrogen release to the
environment and thus air and water contamination. Recovery of ammonia is necessary to …

Gas-permeable membrane technology is useful to recover ammonia (NH 3) from liquid
manures. In this study, phosphorus (P) recovery via MgCl 2 precipitation was enhanced by …

Gas-permeable membranes coupled with low-rate aeration is useful to recover ammonia
(NH 4+) from livestock effluents. In this study, the role of inorganic carbon (bicarbonate, HCO …

Anaerobic digestion (AD) is the most adopted biotechnology for the valorization of

Two industrial-scale membrane filtration pilots were evaluated on their ability to separate
organic matter, nutrients and water from digestates. Both pilots were equipped with a screw …

Due to the pollution characteristics of the wastewater generated in piggeries, these waste
streams have to be treated before discharging into the environment. These wastes have a …

In the transition from a fossil to a bio-based economy, it has become an important challenge
to maximally recuperate and recycle valuable nutrients coming from manure and digestate …

The use of forced mechanical shear for both disc membranes (rotating and vibrating disc
