Ammonia Stripping
Ammonia Stripping
(OP)
I work in a NH3 and urea producing plant.
We a a very important quantity of effluent water that is normally contaminated with ammonia and carbamate that exceeds the ammonia regulations for the effluent of the plant.
We do not have any effluent treatment plant. We only have several ponds to receive de water and then, after controlling the ammonia content we dilute with raw water to meet the limit value.
We are thinking to make a stripping of that water either with steam or air.
1) Any other ideas ?
2) I will appreciate comments (pros and cons) on both stripping methods.
3) How to calculate the required installations and make a budget.
4) Technologies or recommended vendors
5) Any other helpful information to start the evaluation will be very much appreciated.
Best regards to you all.

RE: Ammonia Stripping
In case of air stripping, the installation could be made in plastics, but the gaseous effluent must be postreated,with an adsober bed or sending to flare,
In case of steam stripping, the ammonia could be recovery as ammonia solution.
See my paper "Air Stripping or Steam Stripping?" in the web page www.sitingenieria.com.
For more, just ask.

There are biological/ecological systems available as retrofits to lagoons for nitrification and denitrification.
