Eliopig S.r.l. products

Eliopig offers an innovative solution in the agricultural field with a consolidated technology for nitrates removal.

The plant for nitrates removal exclusively developed by our company, carries out “ammonia stripping” from digestate, which derives from the anaerobic treatment of biomasses and animal manure (biogas plants). The plant of nitrogen stripping allows to reduce more than 60% of the ammonia’s quantity found inside the digestate. This happens through the following steps: 

• The separation of the solid part of slurry (<0,1mm);
• Air/liquid stripping counter-current contact tower;
• Ammonia recovery through absorption of sulfuric acid solution in a scrubber with a production of ammonium sulfate.

The stripping plant for nitrates removal is composed of two columns: the first is dedicated to the ammonia stripping through warm air, while the second one deals with the absorption of stripped off ammonia.

Eliopig nitro-denitro plant is able to remove up to 70-80% of the total nitrogen, through a process of nitrification and subsequent denitrification. It can be applied both to the digestate and to the zootechnical slurry.

What makes our plant different from the rest is the innovative system of oxygenation, which is not based on discs/small plates and carpets located on the tank floor, since they are vulnerable to frequent obstructions because of the settlement of dry matter over the years. Our oxygenation system relies on external reactors where the liquid’s nebulization and the insufflation of microbubbles of compressed air take place. This solution allows the plant to have a more efficient oxygenation, and it makes the maintenance easier and faster through water cleaning.

Eliopig provides clients with ideal solutions to guarantee suitable air exchanges for animals, through natural, manual and fully automatic ventilation systems. Manual ventilation systems are controlled through a mechanization with steel or aluminum levers, and racks that control laminar or vasistas windows, according to the project’s requirements.

Stainless steel tubs and tanks: Eliopig proposes tanks for green maize made of stainless steel AISI304, complete with mixing groups and with an electric engine of 5,5 HP. Tanks have a capacity that varies from 100q to 500q. Eliopig also produces stainless steel tanks, both insulated and for the water and whey storage from 100q to 400q. Furthermore, there is the possibility to install cooling plate exchangers and a mixing group.
