TLDR
Compared to conventional breakpoint chlorination, the PEC-chlorine system is a more economical and efficient means for ammonia nitrogen degradation because of the fast removal rate, no additional chlorine cost, and its use of clean energy (since it is solar-driven).About:

Nanostructured WO3/BiVO4 Heterojunction Films for Efficient Photoelectrochemical Water Splitting
TL;DR: Compared to planar WO(3)/BiVO(4) heterojunction films, the nanorod-array films show significantly improved photoelectrochemical properties due, it is believed, to the high surface area and improved separation of the photogenerated charge at the WO (3)/BiVO (4) interface.

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.
