  • The mystery of electronic water treatment unveiled

    The problems of scale are well known to those living and working in "hard" water areas. Scale is the undesirable consequence of water supplies becoming super-saturated with dissolved minerals.  These problems are of greater significance if found in industrial water systems and commercial buildings. Scaling problems commonly occur, even in "soft" water areas, when a fluid stream is ...

  • What is zeta potential?

    Zeta potential is a measure of charges carried by particles suspended in a liquid (mostly water). Most particles suspended in water and wastewater, e.g. clays, silica, hydrated metal oxides, paper fibers, biological cells, etc., possess negative surface charges in the neutral pH range as shown in Fig. 1 (a simplified view of a particle in a suspension). The particle is said to carry a negative ...
