Ammonia removal from wastewater by ion exchange in the presence of organic contaminants.
TL;DR: The results show that in most of the cases studied, the presence of organic compounds enhances the uptake of ammonium ion onto the ion exchangers, and ion exchange offers a number of advantages including the able to handle shock loadings and the ability to operate over a wider range of temperatures.

Polyvinylidene fluoride (PVDF) hollow fibre membranes for ammonia removal from water
TL;DR: In this article, a mathematical model was presented to simulate the ammonia removal in PVDF hollow fiber modules, and the experimental results indicated that the post-treatment with ethanol is useful to improve both the hydrophobility and the effective surface porosity of the resulting polyvinylidene fluoride (PVDF) hollow fibre membranes, and thus favors the ammonia stripping.
