Example of Management of Nitrogen Removal in a Night Soil Treatment Plant, using the On-Line Total Nitrogen Analyzer TN-4100

Introduction

To prevent eutrophication of closed water areas, agreements with industry have been established which regulate environmental standards, discharged water standards, and type of water area specifications with respect to nitrogen. In addition, it is expected that water discharge controls with respect to total nitrogen (TN) will be reinforced. Devices for measuring TN has been developed, the Shimadzu On-Line Total Nitrogen Analyzer TN-4100 and Total Organic Carbon/Nitrogen Analyzer TOCN-4100. Here we would like to introduce the features of the TN-4100, and the results achieved when this is used to manage nitrogen removal at a night soil treatment plant.
