Gas permeable membranes at atmospheric pressure
High production of livestock effluents.
It reduces the ammonia load in livestock effluents, recovering nitrogen in the form of an ammonium salt, with high fertiliser value.
It is a physico-chemical process that, by increasing the pH of the effluent to be treated, favours the transformation of ammonium to ammonia. This ammonia is recovered by contact with an acid solution, producing an ammonium salt solution. The result is the reduction of the nitrogen load in the livestock effluent and the recovery and concentration of that nitrogen in the form of an inorganic fertiliser product.
