“…The above factors all further influence the salt leaching effect in saline soil (Chaganti et al, ). Moreover, the different infiltration processes among treatments in the present study suggested changes in soil hydraulic conductivity, which is mainly affected by cation exchange capacity (Mandal et al, ), soil structure (Alrajhi et al, ), aggregate stability (Suarez et al, ), clay dispersion (Moreno et al, ) and so on. Further research is required to focus on the above factors in laboratory and field studies.…”

“…Elevated values of the sodium adsorption ratio (SAR) of the source water can lead to a reduction in hydraulic conductivity and rate of infiltration (Suarez, Wooda, & Lesch, 2006). In addition to the source water, initial soil properties such as the soil water content and degree of soil porosity, are important factors that influence saline water infiltration (Ahmed et al, 2012;Alrajhi, Beecham, & Hassanli, 2017;Chaganti, Crohn, & Simunek, 2015). Smaller initial soil water content and bulk density favour saline water infiltration and salt leaching from the soil (Chaganti et al, 2015).…”

Laboratory experiments were conducted to investigate the infiltration of melting saline ice water into coastal saline soil with different initial water contents and bulk densities, together with the redistribution of water, salt and salt leaching after infiltration. Three water contents (5, 10 and 15% at a soil bulk density of 1.3 g cm−3) and three bulk density levels (1.2, 1.3 and 1.4 g cm−3 of air‐dry soil) of saline soil were used, with salt‐free ice comprising the control treatment. The results showed that the depth of infiltration with treatment by saline ice was greater than that of salt‐free ice, and increased as the initial soil water content and bulk density decreased. After infiltration, the soil water content in the upper soil layers increased with increasing initial soil water contents and bulk densities. This trend was reversed in the deeper soil layers. After infiltration of the melting ice water, the saline ice treatment resulted in a smaller soil salt content than the salt‐free ice treatment. The salt contents in the upper soil layers decreased with decreasing initial soil water contents and bulk densities. The largest rate of desalting was observed following infiltration of the melting saline ice water into the coastal saline soil with the smallest soil water content and bulk density. These results indicate that although a similar infiltration process was observed when the melting saline ice water and direct saline water infiltrated the saline soil with different soil water contents and bulk densities, the desalting effect of infiltration of the melting saline ice water was greater than that of infiltration of direct saline water and melting salt‐free ice water. Smaller initial water content and bulk density favoured salt leaching under the infiltration of melting saline ice water. Highlights We evaluated infiltration and soil desalination under melting saline ice into saline soil Rate of infiltration and depth increased with decreasing initial soil water content and bulk density. Soil water content in the top soil layer increased with increasing initial water content and bulk density. Rate of desalting increased with decrease in initial water content and bulk density under infiltration of melting saline ice water.

“…Para a área irrigada, os valores de pH variaram entre 6,3 a 8,6 nas camadas estudadas, não apresentando enquadramento nas classes de elevada e média acidez. Segundo Alrajhi et al (2017), constataram que o acréscimo no pH em solos com textura arenosa e irrigação com aguas de reuso ou com presença de sais tende a elevar o pH do solo devido aos compostos minerais e substâncias disponibilizada pela solução. As classes de maior predominância na área de goiaba irrigada, também variaram entre fraca acidez e fraca alcalinidade, considerada uma faixa ideal para desenvolvimento das culturas.…”

“…The quality of water may be determined by several factors, including the level of metal contained in the water and clarity of water [2,3]. Therefore, it is necessary to take measures to improve the water quality by reducing the metal content until below the allowed threshold [4,5]. This usually requires filtering material as metal element absorber which can simultaneously reduce the color and odor of the water [6,7].…”

The aim of this research is to determine the effect of micro-sized carbon material mass variation from coconut shell leftovers or wastes reinforced with filter paper towards Fe filtration of Mataram canal water. Preparation and synthesis of the micro-sized carbon material are conducted via liquid sonication exfoliation (LSE) method using two main type of equipments, i.e.: a blender and a self-custom made piezoelectric-based ultrasonication apparatus, and then incorporated into a simple filtration apparatus. UV-Vis spectroscopy characterization is done on the micro-sized carbon material solution, while atomic absorption spectroscopy (AAS) is done on samples of Mataram canal water before and after Fe filtration with a mass variation of the micro-sized carbon material. The UV-Vis results show that increasing the mass of the micro-sized carbon material increases the absorbance values at the same wavelength. The AAS results confirm that the greater the mass of the micro-sized carbon material the smaller the Fe content inside the water samples after filtration. The lowest Fe content of 0.016 ppm is obtained for 3 grams of the micro-sized carbon material.
