The Impact of Filter Membranes to Structural Changes in Low Mineral Water

Abstract

This paper presents the structural changes that can be identified in low-mineral Aqua Viva water using four separate samples corresponding to different stages of its filling, 1. The stage before final treatment (inlet pipework) 2. After the first treatment phase using polypropylene membrane surface porosity 2.5 μm. 3. After the second treatment phase using polypropylene / glassfibre membrane porosity 0.45 μm. 4. After the final treatment phase using the double polyethersulfone membrane porosity of 0.2 μm. As a comparative parameter is used demineralized water Aqua Purificata with conductivity of 0,055μS/cm. Characterization of water was done by two methods, Opto-Magnetic and NIR Spectroscopy with Aquaphotomics approach, based on the interaction of light and water. Aqua Viva manifests itself as a strong pair - diamagnetic and its clear structuring occurs only after treatment at the level of 0.2 μm. Resulting Aquagrams suggest that only the 0.2 μm filter leads to the appear- ance of an increased number of water dimer and its major reorganization.
