- In December 2022, Dynamized Technologies therefore had a Belgian independent accredited laboratory (Euraceta – Eurofins) analysis of 310 pollutants (heavy metals, pesticides, drugs, plasticizers, phthalates, chlorine etc.) in legally drinkable tap water in Belgium, i.e. significantly more than the number of parameters on which city water distribution companies provide information! This analysis confirms that tap water nevertheless contains several tens of residual pollutants (pesticides, heavy metals..) whose concentration rates are higher than the legal limits ! (according to the European Directive 2020/2184 on the Water Intended for Human Consumption) or exceed the accepted precautionary thresholds (maximum health values) because health caution makes us consider the pesticide metabolites as relevant. These pollutants could therefore not be filtered by city water treatment plants. This is worrying given that some of them are endocrine disruptors that may eventually cause (through chronic consumption) a sanitary risk.
- After the filtration & dynamization of the water by the Biofilter and Biodynamizer, several residual pollutants are neutralized (their concentration decreases below the legal concentration thresholds of the EU Drinking Water Directive or the health caution thresholds for these pollutants which can be considered relevant) which allows city water to become again, for parameters in excess, biocompatibel water!
- This analysis confirms that the combination of the Biofilter (filtration) + Biodynamizer (dynamization) clearly leads to a very broad spectrum of water purification.
The Biofilter retains PFAS:
- Activated carbon is considered the best media for filtering PFAS (> 80% efficiency) due to the specific properties of activated carbon: electrostatic & hydrophobic interactions and then adsorption (retention/capture) in its porous surface of PFAS (depending on the size of its micropores) . The adsorption surface of the Biofilter is 3,000 m2/g of activated carbon x 3 kg, i.e. an adsorption surface 33 times larger than that of standard filters, so it will be even more effective in filtering PFAS!
- Several international scientific analyzes confirm the superior effectiveness of activated carbon in retaining PFAS in water.
- The European Drinking Water Directive (Directive 2020/2184 of the European Parliament and of the Council of 16 December 2020 on the quality of water intended for human consumption) sets the limit for PFAS in water at 100 nanograms per liter (ng/l) for the sum of the concentrations of 20 PFAS and 500 ng/L for all PFAS.
