2141-006-PL Water PetroChek PAH Fluorometer only to monitor real-time concentrations of PAH by Modern Water

PetroChek™ PAH enables in-situ, real-time, monitoring of crude and refined hydrocarbons within both fresh and marine water systems. The monitor detects fluorescent poly aromatic hydrocarbons (PAHs) that are inherent in crude oil and refined fuels and lubricants.

Accidental or deliberate spillage of crude or refined hydrocarbons can have catastrophic consequences to freshwater and marine environments. Impacts to fauna and flora can be devastating and in freshwater environments it can lead to significant damage and costs to drinking water treatment plants. In cases where there is historical contamination, PetroChek™ PAH can be effectively used as a portable or online monitor to identify and quantify the problem or help control the remediation process. Typical treatment technologies include aeration and activated carbon and big savings can be made through effective monitoring and control.

The system can combine a sensor with a depth rating of 600m with either a wireless roamer/battery that can connect to a tablet/PDA or laptop connectivity. It provides a low cost high performance sensor for marine, freshwater or process applications. PetroChek™ PAH can easily be adapted to operate inline/online with a specially designed flow cell and pumps requiring very little maintenance or calibration

Process explained

Fluorescence is the emission of light by a substance that has absorbed light. In most cases, the emitted light has a longer wavelength, and therefore lower energy, than the absorbed light. Fluorometry is the measurement of this fluorescence. Different molecules absorb and emit light at specific wavelengths. In order to effectively use Fluorometry as a tool for environmental analysis the specific wavelengths of the absorbed and emitted light for the target molecules/compounds needs to be known. Modern Water fluorometers use LED light source to excite the molecules and then measure the emittance at the desired wavelength. The intensity of the emitted light provides the concentration of the target compound.

2141-089-PL BODChek (as BOD) Fluorometer only to monitor BOD by Modern Water

BODChek enables in-situ, real-time, monitoring of Biological Oxygen Demand (BOD) within both natural water systems and water processing plants. The monitor detects fluorescent proteins that are inherent within sewage and slurry and provides an output in BOD equivalent units.

The principle behind the measurement is the excitation and fluorescence of tryptophan-like compounds in the UV wavelength band. Tryptophan is an essential amino acid in human and animal diets. It is associated with microbial activity i.e. sewage and faecal contamination of wastewaters and has been shown to correlate with both BOD and bacterial contamination.

An internal calibration factor is used to convert the Tryptophan-like fluorescence to the reported BOD equivalent value in units of mg/L. The use of fluorescence provides signal detection sensitivity far superior to optical absorption methods currently in use, while the real-time reporting of BOD equivalence enables the measurement to be used for process control, which is not possible with conventional 5 day BOD laboratory techniques. BODChek provides a cost effective solution to organic pollution monitoring.

The system can combine a sensor with a depth rating of 600m with either a wireless roamer and PDA or laptop connectivity. It provides a low cost, high performance sensor for marine, freshwater or process applications.

A Windows based interface is provided that allows the user to both plot and record time stamped data when operating the BODChek directly from a PC.
