IMA-Met is a granular filtering product mainly used for the removal of dissolved heavy metals in water, whether from wells, mains or irrigation, from natural or industrial discharges. The application of this specific filter bed reduces the values below the limits set by the World Health Organization.

IMA Water Technology ships IMA-Met bags in 25kg units for insertion into filters or for replacement once the previous bed has saturated its heavy metal absorption limit.

If a fully assembled, ready-to-connect heavy metal removal system is required, please contact our technical department. As experts in water treatment, with more than 30 years of experience in the sector, we will advise you to optimize your specific case.

Technical characteristics of IMA-Met filter media for heavy metal removal from water

The IMA-Met bed is obtained from highly pure products, being specially designed for its integration in drinking and industrial water treatment lines. It has, therefore, the necessary safety parameters for its use in water for human consumption.

IMA-Met has a high performance in the elimination of:

▸Antimony ▸Phosphates ▸Cadmium

▸Chromium ▸Vanadium ▸Molybdenum ▸Molybdenum

▸Nickel ▸Lead ▸Silicates

▸Uranium ▸Copper ▸Fluorine ▸Fluorine

▸Arsenic ▸Selenium ▸Zinc ▸Zinc ▸Selenium ▸Zinc ▸Selenium ▸Zinc

• Bulk density: 700 g/m3
• Absorption surface: 330 m2/g
• Particle size: 1 - 1.8 mm

IMA-Met Operational Specifications

It is recommended to follow the following indications regarding the use of IMA-Met in order to optimize its adsorption and metal removal capacity:

□ Installation of antibacterial equipment to slow down the biological development inside the filters.

□ Oxygenation of the water prior to absorption to improve the assimilation of contaminants.

□ Depending on the application, a minimum contact time of 3 to 5 minutes of the specific flow rate inside the filtration equipment must be guaranteed.

□ As far as possible, the raw water should be free of turbidity, non-calcareous and with a positive redox potential.

□ The maximum capacity for specific adsorption will ultimately depend on the parameters of the inlet water. Therefore, the extent of the output water will be influenced by hydrochemical composition, molecular ionic strength, pH value, reactive time and temperature.

Therefore, from IMA Water Technology we always request an analysis of the raw water for the specific adjustment of the treatment system, achieving an optimal performance of both the equipment and the filter bed.
