BIOAqua Online Ammonia Water Analyser



Ammonium in spring water is usually found at very low concentrations, with levels below 0.1 mg of NH4+/l. Basically, its presence is due to excretions from fluvial fauna or as a product of decomposition. Plants take it up as a source of nitrogen during their natural cycle.

The presence of ammonium at higher concentration is usually an indicative of urban or livestock sewage contamination. It could also come from seepage from fertilized soil or have an industrial origin from the rubber, food, textile or other industries, or from cooling processes

Measuring ammonium in water is an efficient warning method to prevent toxic effects on the environment given that changes in pH and temperature can turn it into its gaseous form (NH3), which is much more toxic than the dissolved ion (NH4+)

The BIOAqua series On Line Ammonia Water analysers covers the whole range and provides all the tools for measuring this parameter.

  • BIOAqua Silver series Online Ammonia Water analyser is for detecting incidents in surface waters with low levels of ammonium.
  • BIOAqua Gold series Online Ammonia Water analyser is a low maintenance analyser for mid-range measurements.
  • BIOAqua Platinum series On Line Ammonia Water analyser is designed especially for measuring ammonium in sewage in general, capable of withstanding high levels of turbidity.

The choice of model will be determined by the user’s needs and requirements.

 


BIOAqua Online Ammonia Water Analyser – Operation

 

All BIOAqua series Online Ammonia Water analysers can operate in:

 

Automatic mode:

 

The equipment takes readings automatically.
It includes a self-calibration system that prolongs the system’s autonomy.
Data collected is sent in real time to a local or remote control centre for analysis and use.

BIOAqua series Online Ammonia Water analysers carry out ongoing treatment of the measures that enables them to generate and send out alerts to other equipment (BIOAqua Online Auto Sampler sample takers) or systems (monitoring networks).

Manual mode:

The measurement process can also be carried out locally by sending commands from the equipment keyboard, or by remote control from the control centre.

BIOAqua Online Ammonia Water Analyser - System Components

  • Capture system that maintains the sample unchanged, for which there are two options:
    • Peristaltic pump – Takes samples by water suction.
    • Vacuum pump – Takes samples without coming into contact with the pump elements.
  • Cooling system for preserving the samples at 4°C.
  • Data monitoring, acquisition, storage and transmission system.

 

Unique Characteristics of BIOAqua Online Ammonia Water Analyser

The BIOAqua series On Line Ammonia Water analysers is an Analyser that is optimum for determining the concentration of ammonium in levels below 0.1 ppm with a high level of accuracy, ensuring a perfect characterisation of the water mass.

Its application is mainly centred in the control of surface waters, rivers, fish farms, wells, etc., which generally have a low degree of turbidity. Particularly useful for monitoring intakes of water to be used for the production of drinking water. Its use extends to any type of water where controlling low levels of ammonium is necessary, for example in fish farms.

Based on the FIA system with potentiometric measurements, The BIOAqua series On Line Ammonia Water analysers combines a selective electrode of NH4+, with a semi-permeable membrane that prevents the sample from coming into direct contact with the electrode, thus eliminating any type of interference

 

Benefits of BIOAqua Online Ammonia Water Analyser

 

  • This system can help identify the pollution issues relating to presence of ammonia in the waste water stream as presence of ammonia in waste water will aid biological growth as plants take up nitrogen as their source

  • Many plants who produce and use ammonia can use to monitor their outlet for presence of ammonia before they could let the effluent out of their plant

  • In Aqua culture measurement and control of levels of ammonia in water is vital for aquatic spices survival

 

BIOAqua Online Ammonia Water Analyser - Specifications
BIOAqua Silver series On Line Ammonia Water analyser (Silver Analyser - 0,01 to 4 ppm NH4+)

BIOAqua Silver series On Line Ammonia Water analyser is the ideal analyser for determining ammonium concentration with great accuracy, ensuring perfect characterisation of the water mass.

Its application is centred mainly on monitoring surface waters, rivers, wells, etc. generally with low turbidity. Particularly useful for monitoring intakes of water to be used for the production of drinking water.

Based on the FIA (Flow Injection Analysis) system with potentiometric measurements, BIOAqua Silver series On Line Ammonia Water analyser combines a selective electrode with a semi-permeable membrane that stops the sample coming into direct contact with the electrode, thus eliminating all types of interference.

BIOAqua Gold series Online Ammonia Water analyser (Gold Analyser - 0,1 to 10 ppm NH4+)

BIOAqua Gold series Online Ammonia Water analyser is characterised by its low maintenance and offers the ideal solution for environments that do not need a low detection limit.

Based on an FIA system and ISE selective electrode, BIOAqua Gold series On Line Ammonia Water analyser features low consumption of reagents.

 

 

 

 

 

BIOAqua Platinum series On Line Ammonia Water analyser (Platinum Analyser - 1 to 100 ppm NH4+)
BIOAqua Platinum series On Line Ammonia Water analyser is the analyser best suited for applications with high levels of turbidity and/or where ammonium levels are high, such as highly polluted rivers, sewage collectors, treatment intakes, etc. Designed to measure values of up to 100 ppm of ammonium, it has an effective cleaning system with low reagent consumption to guarantee very low maintenance levels.
