AmNiSys on test
South West Water in succesful AmNiSys trials

South West Water goes for simplicity and reliability

 Process investigations at South Moulton Sewage Works Devon, required continuous monitoring of inlet sewage for NH3-N. Experiences with other in-situ devices had proved troublesome, so Envitech offered a trial AmNiSys unit to test at this location. Considering the difficult nature of crude sewage, performance exceeded all expectations, with the air clean system keeping the unit reasonably clean, and the analytical comparisons being acceptable (9.0 mg/l vs 9.2 mg/l on the AmNiSys) even after 2 months unattended operation
Due to the success of this installation, ease of use, lack of maintenance or reagent requirement, further units have been purchased for use on works outfalls.

River abstraction protection with AmNiSys

Following the success on wastewater applications, SWW have trialled the Amnisys on a river abstraction application at Pynes on the River Culne.
The river is very flashy and runs through rich agricultural land used for dairy farming. This can allow ammonium compounds to get into the supply of the treatment works.
Low-level ammonium has historically been monitored using a colorimetric batch system.

However a more cost effective, continuous analysis instrument has been sought in order to reduce costs and manpower requirement and to avoid missing fast transient spikes.
An Amnisys was sited in the inlet analysis tank at the river intake, and a two-point calibration procedure, using the river water and a "1 mg/l spiked sample" was performed.

The results have been excellent with measurements well below 0.1mg/ltr, verified by independent analysis.
Two units are now installed, one at Pynes the other at Trenear in Cornwall.
