UV400 ONLINE WATER ANALYSER

The UV400, based on a modular concept, allows to monitor simultaneously many different parameters for waste water or drinking water treatment plants as well as river monitoring stations.

UV 400 ONLINE WATER ANALYSER
The UV400, based on a modular concept, allows to monitor simultaneously many different parameters for waste water or drinking water treatment plants as well as river monitoring stations. Each parameter corresponds to a specific optical module that can be selected by the user while ordering the analyser, depending on the application. Mainly based on UV spectroscopy, well known for its stability and low operating cost, the UV400 can measure parameters like organic matter, ammonia, nitrate, aromatics hydrocarbons (PAH), colour, hydrogen sulphide and chlorophyll A.
 
Complementary modules allows the measurement of phosphate by colorimetric method and turbidity by a visible or infra-red laser diode.External probes can be added for physicochemical parameters like pH, ORP, dissolved oxygen, conductivity and turbidity.Thanks to its automatic cleaning system and its extremely long life time lamp, the maintenance is roughly limited to the periodic refill of the inexpensive cleaning solution and eventually reagents depending on the parameters.
 
UV-VISIBLE SPECTROSCOPY
  • Most of the measurements (UV254, NH4, H2S, NO3, Colour, PO4, PAH, Chlorophyll A) are based on the UV-VIS spectroscopy that brings fast and stable measurements with a simple hydraulic circuit for a high reliability.
  •  
  • All the measurements are done within 5 seconds except PO4, NH4 and H2S that require about 3 minutes.
  •  
  • The patented flow cell allows very high level of suspended solid without clogging. The turbidity of the sample is automatically compensated by a dual-wavelength method as shown on the figure.
  •  
  • The UV source is a xenon flash lamp specified for 109 flashes that corresponds to more than 10 years of life time with one measurement every minute.
  •  
  • Physico-chemical measurements (pH, ORP, Dissolved oxygen, Conductivity) can be added to the internal measurements by using external probes. The dissolved oxygen probe is based on fluorescence method for a lower maintenance and higher stability.
  •  
  • Three external turbidity probes (high, medium and low range) are also available if the measurement need to be done in situ, for example before filtering.

AMMONIA AND HYDROGEN SULPHIDE: A UNIQUE METHOD

The ammonia and hydrogen sulphide measurement are based on the UV absorption of the ammonia gas or hydrogen sulphide gas after a stripping phase. Consequently, the turbidity or colour of the sample has absolutely no influence and measurements can even be carried on activated sludge. The ammonia gas has a typical periodic absorption spectrum that is analysed using a fast Fourier transform (FFT) that brings an exceptional selectivity. No interference has ever been reported after years of operation on many different applications. A small quantity of NaOH solution is added to the sample for ammonia, or hydrochloric acid for hydrogen sulphide.

MULTIPLEXING SYSTEM
When different streams need to be analysed, for example inlet and outlet of a plant, an optional multiplexing system delivers relay contacts to control external electric-valves or external pumps.
Up to 6 different streams can be selected
The measuring channels can be either duplicated (each one having its own 4-20mA output or MODBUS register), or measured sequentially to fit with the maximum of 16 measuring channels (a MODBUS register tells which stream is currently being measured).
ROBUST INDUSTRIAL PROBES

All the probes are specially designed for harsh environments with high level of suspended solid. More…

UV400 ATEX ONLINE WATER ANALYSER

The UV400 ATEX, based on a modular concept, allows to monitor one or several parameters for process water, cooling water or waste water. The special enclosure and air purge system allows to use it on hazardous areas classified “Ex” like refineries and chemical plants.

Thanks to its automatic cleaning system and its extremely long life time lamp, the maintenance is roughly limited to the periodic refill of the inexpensive cleaning solution and eventually reagents depending on the parameters. A web-based interface allows the control and the troubleshooting at distance though an ATEX Wi-Fi or Ethernet connection using a standard browser on a computer or tablet.

 

EX PZ PROTECTION ACCORDING TO EN94/9/EC
The UV400 ATEX has a IP 65 stainless steel enclosure with an air purge system Ex pz to work on hazardous areas classified “zone 2” where a risk of explosive atmosphere is present like refineries or chemical plants. Two alarm contacts are provided if the pressure inside the enclosure drops below the adjustable setting points. This alarm can be used to switch off the power of the enclosure. A thermostatic vortex cooler can be installed as an option to maintain a moderate temperature inside the enclosure for outside use with high ambient temperature. After certification, a marking plate can fixed on the enclosure with the specified marking, example :

LOW MAINTENANCE AND HIGH RELIABILITY
The design has been specially oriented for low maintenance and high reliability on the measurements. To avoid deposits on the optical windows and tubing, the UV400 ATEX has a built-in automatic cleaning system that injects a 5% sulphuric solution normally once day. An auto-zero is performed at the same time to avoid any drift of the measurement. The patented flow cell limit the risk of clogging inside the flow cell. The level of the cleaning solution as well as reagents for H2S, NH4 or PO4 can be controlled at distance to plan the refill. More…
