What makes our technology so unique?

  1. With iFLUX samplers we simultaneously monitor the water flow velocity (‘waterflux’) and the contaminant spreading (‘Compound flux’) in groundwater.

    The key innovation of iFLUX is situated in the self-developed, validated and patented cartridges. iFLUX delivers several types of cartridges:

    Water flux cartridges
    contain a set of water soluble resident tracers that independently leach into the groundwater according to the flow conditions.

    Compound cartridges
    contain pre-processed sorbents that capture the pollutants of interest. The contaminant fluxes in the groundwater are being determined through adsorption and recovery processes.

    Each type of cartridge contains a different type of sorbent. The following compound cartridges are commercially available at the moment:
    • (Volatile) Organic Compounds (VOCs, BTEX, PAHs,...)
    • Nutrients (nitrate, phosphate, ammonium,...)
    • Heavy metals (nickel, zinc, copper,...)

    Our current offer is able to capture 90% of the most common contaminations. New cartridges to add missing parameters will be worked on for future improvements.

  2. Depending on site specifications, different cartridges are combined into our modular and expandable iFLUX sampler system, which perfectly fits into existing monitoring wells and is able to sample several types of pollution at the same time. Each iFLUX sampler is exposed to the groundwater ranging from 1 week to up to 6 months.
  3. The iFLUX sampler has been designed to tightly fit in the monitoring well. The permeable cartridge wall brings the contaminated groundwater in direct contact with the sorbents. By performing targeted flux measurements in different monitoring wells, you are able to get an accurate image of the discharge over a complete area.
  4. After a certain period the iFLUX samplers will be retrieved and analyzed by a certified laboratory. Our validated and certified analyses deliver reliable flux data.

    The raw flux data are being converted by iFLUX into representative information, depending on different environmental parameters (geology, monitoring well characteristics...). The interpreted data deliver a clear image of the spreading risks of the examined compounds. Through clear and visual representation, you will know the direction, the spreading and the concentration of the pollution.

Traditional measuring techniques?

Traditional concentration measurements only take a snapshot of the underground situation. This measurement solely represents the concentration of a pollutant at a certain time at a specific place.

Based on measurements of the groundwater level, simulations are being executed to estimate the expected groundwater flow. There is no direct measurement of the water or pollutant flux. This method is far from precise and secure.

Flux measurements, on the other hand, deliver more accuracy. Flux samples give more certainty about which contaminants are present in the soil, how they move and at what speed.
