Abstract
The ammonium elimination in continental waters is a problem solved by the action
of zeolites, through cation interexchange. Thls is used, for example in factories in
which the water reuse is a necessary process, or to avoid the increase of
contamination due to wastes. In saline waters or in seawaters, the problem increases
due to the saline cations inhbiting the interchange. So, it is necessary .to improve
the capacity of zeolites by the preparation of new varieties, named products of
zeolitic nature (PZNs) with better yields, which have been obtained with th~s aim.
Good results have been reached. By preparation of new PZNs, elimination of 20%
of initial ammonium are reached. These are the best results referenced in the
bibliography up to
