Ammonia Monitoring Is Simple With The Q45N From ATI

Date Added: 10th April 2012

Both in wastewater treatment applications as well as processes which involve fresh water, ammonia monitoring is a vital part of quality control as well as process control. Most in-line systems used to monitor the levels of dissolved ammonia in water tend to be quite expensive and could hardly be accused of being user-friendly. However, ATI’s Q45N dissolved ammonia monitor presents a high performance, lower cost and easier to use alternative to the selective ion electrode or colorimetric based instruments which are the standard in many plants.

Rather than using SIE or colorimetry methods, the ATI Q45N is an ammonia monitoring system which takes an effective and very simple approach to this task, instead using reaction chemistry to determine the ammonia concentration in water. The ammonia in the sample is converted to a monochloramine compound which contains the same concentration of ammonia as the original sample – the Q45N’s ampermetric sensor measures the chloramine concentration of this compound to provide an accurate reading of ammonia levels without interference from free chlorine dissolved in the sample.

Analytical Technology offers two models of Q45N dissolved ammonia monitor: a fiberglass Nema 4X enclosed version for easy mounting as a single unit and another which is composed of a separate monitor and reaction chemistry module, which is better suited for applications where in-line ammonia monitoring is inconvenient or otherwise undesirable. Samples may be drawn in via a inlet filter on the side of the enclosure for quick and easy monitoring, with excess sample volumes being simply bypassed to any drainage which happens to be near at hand.

The Q45N offers not only the reliable and accurate measurements of dissolved ammonia which is mission critical for many processes, but it does so without needing the frequent and complex calibration to correct the drift to which SIE sensors are typically prone. It’s simply a better choice for any application where constant ammonia monitoring is important to the outcome of processes; and at a cost which is significantly lower than other types of dissolved ammonia monitors, it’s one which is well on its way to becoming the industry standard.
