“…Application of magnetic treatment to water still remains a controversial topic 49,50 and the various effects and mechanisms are still obscure -at the very best, not fully understood. At the moment, there is no unified verdict on the mechanism under which this method of water treatment is executed.…”

Scaling produces devastating effects to both households and industries. It causes pipe blockages, damage to desalination membranes, and reduction in efficiency of heat exchangers and boilers.Chemical treatment of scale is effective but renders water unfit for human use and potentially alters the ecological balance with release of substances capable of promoting eutrophication and algal blooms.'Greener' means of addressing this issue must be brought forward.Anti-scaling magnetic units could be a potent alternative, because they cost less and are easy to install.The benefits are both economic and ecological -reduced expenditure on scale remediation, improved water conditions for human use and reduction in release of harmful substances to the environment.Scaling is the bane of households and industries that make use of water frequently. The consequences are so egregious that harmful chemicals have been sort after to remedy the situation. These chemicals, though efficacious, do more harm than good because they render water unsuitable for human consumption and cause ecological imbalance. Anti-scale magnetic water devices offer a cleaner solution to handling the scaling dilemma. This method of water treatment has been in existence for more than a century and is still the subject of much debate today, with the method being viewed with much skepticism, although evidence of its efficacy has been provided on countless occasions. Reports are given on several effects associated with magnetic water treatment, as well as proposed mechanisms. Yet no general consensus has been reached regarding the treatment method's mode of operation, which could explain the cynical reception magnetic water devices often receive. Insights into the enigmatic technique of magnetic water treatment attempt to explain magnetic effects on water and its constituents, citing explanations, which are unrelated with the current principles of magnetism. The several reports and accounts that involve the use and application of anti-scale magnetic water treatment are elucidated with special focus on calcium carbonate scale and its transformation.

“…Figure 9.5(a) shows the clamp-on type magnet with four permanent magnets attached to a nonmagnetic pipe, an arrangement for easy installation and the maximum performance of the magnetic treatment of water. More recently, Gilart et al [44] proposed a clamp-on permanent magnet system for high flow capacity applications, where the water flow rate is at the order of several hundred cubic meters per hour (see Figure 9.6). In this case, water flows through the annulus gap between the magnet and pipe wall with minimum pressure loss.…”

“…The reduction of honey's viscosity might not be sufficient to effectively improve the flowability of the honey. Moreover, application of magnetic treatment had merits of operation costs after initial installation (Gilart et al, 2013). Therefore, this research was aimed at applying a newly designed magnetic field apparatus, which could generate higher effective magnetic field strengths and investigate the effects of magnetic field on rheological and physicochemical properties of honey at ambient and low temperatures.…”

Summary A non‐thermal technology using magnetic field (MF) can improve flowability of honey while maintaining its physicochemical quality. Effects of MF treatment on rheological and physicochemical properties of longan honey exposed to MF for 2 h at 15 °C and 28 °C were investigated and compared with those of non‐MF samples. Increasing MF strength at 28 °C caused a reduction in firmness (P ≤ 0.05), but not in consistency, index of viscosity and cohesiveness. The effects at 15 °C were greater. Newtonian behaviour was observed for all samples. Shear stress and viscosity were significantly reduced with increasing MF strength at 15 °C (P ≤ 0.05), but less at 28 °C. pH was also decreased. Total soluble solids content was increased at both temperatures (P ≤ 0.05). Colour index was not significantly affected by MF, whereas optical density was slightly increased at high MF strengths (P > 0.05). L* values for the MF treated samples were increased (P ≤ 0.05), giving lighter and more pleasant colour to the honey. MF treatment improved overall qualities of honey.
