“…Deposition of scale due to entrapped oxygen increases corrosion. When the surface of any pipeline or water-using systems becomes scaled, this insulating scale reduces the efficiency of the system, increases fuel requirements and maintenance [58][59][60][61] . Therefore, there is an ever increasing demand for effectively scale prevention/elimination technique, not only economically, but to insure the minimum environmental pollution attainable.…”

Magnetic water treatment (MWT) techniques have shown promising potentials in different areas specially agriculture. Safety, compatibility and simplicity, environmentally friendliness, low operating cost and not proven harmful effects are the main advantages of electromagnetic field (EMF) over conventional methods for water treatment. Magnetized or magnetic water (MW) possesses unique physical and chemical characteristics making it a multi-purpose compound with potential benefits in medical treatment, industrial as well as environmental applications. The unique physical and electrochemical characteristics of MW have attracted research interests to develop different devices and techniques in agricultural and environmental applications. Improvements of irrigation water quality and quantity, crop yields and quality, soil improvement and water saving are some of the reported benefits of MWT in agriculture. In addition, magnetic field treatments have shown beneficial effects on the germination of seeds, plant growth and development, the ripening and yield of field crops. The main challenge in applications of MW in agriculture is efficient integrating of irrigation components, designing suitable pumps compatible with technical and field requirements of magnetic MWT systems. The present study reviews the applications of MW in agricultures. The practical challenges in using MW as well as future perspective are discussed.

“…If the scale is patchy, the differential aeration between the clean and scaled surface facilitates the built up of a corrosion cell. To prevent scale formation several nonchemical methods of water treatment that are based on permanent magnetic, electromagnetic, electric, electrostatic, ultra-sonic, radiation have been introduced [54][55][56][57]. One of the promising applications of MWT is to suppress water-scale deposition on the inner surface of boilers, heat exchangers and pipelines.…”

“…MFs in appropriate spatial and intensity conditions can modulate the turbulence in the fluid. Magnetically structured water can remove scaling from water distribution system and also prevents new scaling [54][55][56][57]. In agriculture and farming, magnetized water for irrigation can save irrigation water [58].…”

Magnetic water treatment (MWT) is a relatively new technique in environmental management. Magnetic field exposure alters physical and chemical properties of water molecules resulting in unique characteristics.Magnetized water has shown various properties with possible applications in different fields of environmental management. Scale prevention/elimination, soil enhancement, plant growth, crop yield, water saving, and wastewater treatment are some of these applications. Magnetic treatment of water restructures the water molecules into tiny, uniform and hexagonally structured cluster easing their travel through the passageways in plant and animal cell membranes. In addition, toxic agents cannot enter the MW structure. These features make MW a bio-friendly compound for plant and animal cells. The present study reviews the applications of MWT in environmental management. The recent advances of MWT in different fields of environment management are discussed. In addition, the mechanism of action of MWT in different applications and future perspectives are discussed.

Abstract. Porous Silicon (PSi) is synthesized by Ag assisted electroless etching and characterized by Scanning electron microscopy (SEM). The effect of etching time on the optical reflectivity, optical absorbance of PSi is investigated. Reflectivity measurements showed gradual decrease in the reflectivity with respect to etching time. 45% reflectivity of bare silicon drops to 10% for 2 hours etching and to 6% for 3 hours etching. The decrease in the reflectivity shows that the PSi can be employed as an anti reflecting substrate in optoelectronic devices. The absorbance measurements revealed that the average absorbance of PSi is 0.60 in the wavelength range 300-800 nm after 2 hours etching. From the photoluminescence spectra it was found that PL intensity of PSi is high compared to bare silicon wafer. Static water contact angle measurements were performed to examine the hydrophobic properties of the PSi prepared under different conditions. The porous silicon surface after etching has been demonstrated to be suitable for self cleaning applications.
