Effect of Magnetizm on Saline Irrigation Water Properties

Abstract

Egypt government's strategy for horizontal expansion and overcoming difficulties in the agriculture sector, the salinity of irrigation water and soil are the major challenge factors. Moreover, salt concentrations cause the clustering of soil aggregates. As a result, this leads the soil to form a thin, surface layer that prevents the growth of seedlings and affects the soil's hydrological characteristics. However, researchers demonstrated that there is debate about the usage of magnetic water treatment. A magnetic device was used to treat saline water to answer these questions. This consideration was made to study the effect of magnetization on saline water, as well as to study the re-magnetization effect 'bypass' on saline water. Additionally, different levels of re-magnetization were applied up to five times, with saline water and standard water treatments as a reference. It was found that magnetization affects dynamic viscosity, dissolved oxygen and pH. Also found a positive effect of magnetization under transmission electron microscopy, and on the formation of fungi. On the other hand, magnetization does not affect electrical conductivity. Besides that, laboratory experiments on the stability of magnetization show that it lasts for 48 hours. For the germination and growth rates on maize and pumpkin, results were 85% for treated saline water instead of 48.86%, and 57.14% for saline water without treatment, i.e., the magnetization of saline water showed a significant effect. Lastly, there is no significant effect between the levels of re-magnetization of saline water. Therefore, it was recommended using the magnetic treatment once for saline water.

Evaluation of saline and magnetized water on emitter hydraulic performance and clogging in drip irrigation

“…Eu improved by approximately 0.2, 0.6, 1.1 and 1.8% at 1000 ppm, and by approximately 0.8, 0.9, 1, and 2% at 2000 ppm, as compared to non-magnetic treatments at 75, 100, 125, and 150 kPa respectively. It should be mentioned that the classification went from “good” to “excellent” that in agreement with 30 who indicated magnetic increased emission uniformity and Christiansen’s Uniformity coefficient.…”

“…Moreover, salinized water re-magnetization levels have no significant impact. The magnetic treatment for saline water was therefore advised to be used just once (single bypass) (Zeineldin et al, 2023).…”
