Title:
PROCESS AND DEVICE FOR REDUCING THE NITRATE CONTENT OF WATER
Document Type and Number:
WIPO Patent Application WO1996020136
Kind Code:
A3
Abstract:
To decrease the nitrate content of water, it is proposed to reduce nitrate to nitrogen in two stages. The first of these stages is a photochemical reduction to nitrite, and the second stage is a reduction of nitrite to nitrogen using amidosulphuric acid.
