“…The chloride and sulfate ions drastically reduce corrosion resistance (Vazdirvanidis et al, 2016;Yang et al, 2012). Steel is easily susceptible to pitting corrosion in solutions containing aerated chloride with pH in a wide range (4 -12.5) at room temperature (Wang et al, 2015).…”

“…The effect of the different water quality parameters including pH, residual chlorine, total organic carbon, conductivity, dissolved oxygen, hardness and alkalinity influences corrosion and the formation of scale inside the metallic pipe (Cui et al, 2016). Vazdirvanidis et al (2016) noted that the accelerated corrosion of parts of a water pump was probably caused by the presence of sulfates, sulfides and chlorides that caused a severe chemical attack on the various metallic components of the pump. Drinking water is commonly corrosive at a pH of 6.5 to 7.5 and with a low alkalinity.…”

“…Considering the economic cost and the health risks related to incrustation and corrosion; the corrosive or fouling tendency can be analyzed using the indirect methods shown in Table 1. The equations of this table have been used to calculate the LSI (Liang et al, 2013;Alsaqqar et al, 2014;Choi et al, 2015;Vazdirvanidis et al, 2016;Gholizadeh et al, 2017); the RSI (Alsaqqar et al, 2014;Vazdirvanidis et al, 2016;Achari et al, 2017); and the LRI (Mirzabeygi Rev. Ambient.…”

The quality of drinking water flowing in a distribution network can possess corrosive characteristics that may cause the material degradation of pipes and accessories. This problem can result in reduction of the service life of pipes and create a major public health problem. The agreement between the physical-chemical water quality analysis and national standards are not enough to confirm the balance of the water quality in terms of corrosion. In order to predict pipe corrosion in water distribution system networks, the corrosive trend was evaluated using the Langelier (LSI), Ryznar (RSI), and Larson-Skold (LRI) indexes based on measurements of pH, temperature, total dissolved solids, alkalinity, calcium hardness, sulfate and chloride. This study was setup with 180 samples collected in six zones of the distribution network, from July to December of 2017, according to the standard methods for the analysis of drinking water. The results indicate a variation of the LSI from -1.22 to -1.68; RSI from 9.75 to 10.52 and LRI from 0.46 to 0.77. A linear model was fitted for each index to predict the corrosion with the water quality conditions of this study case. Therefore, the drinking water of the city of Azogues, Ecuador has a corrosive tendency from significant to severe. Corrosion indices were calculated to provide useful information on the water's corrosiveness. These results indicate the need to constantly monitor the corrosion rate in the distribution network and conduct a laboratory study to adjust effective parameters such as pH, in order to control corrosion.

“…Many types of corrosion such as pitting corrosion is a material failure mechanism of a component that occurs due to an aggressive environmental influence, this is indicated by the presence of chloride and sulphide that accelerate the corrosion process above 50-55 O C [4]. Steel is a metal that is widely used in marine ship structures that are strongly influenced by moisture and atmospheric ocean temperatures resulting in extremely vulnerable corrosion.…”

Cowpea is a crop with great economic, social and food importance in semi-arid regions, but its production is drastically reduced by the water deficit in these regions, requiring better management strategies that allow the crop's production. This study therefore aimed to evaluate the photosynthetic efficiency and production of cowpea cultivars under deficit irrigation replacement levels. The experiment tested three cowpea genotypes (G1 = 'BRS Aracé', G2 = 'BR 17 Gurguéia' and G3 = 'BRS Marataoã') and four irrigation depths (40, 60, 80 and 100% of ETc), resulting in a 3 x 4 factorial scheme, arranged in randomized complete blocks design with four replicates. During the experiment, the gas exchanges, chlorophyll a fluorescence and production of the cowpea genotypes under deficit irrigation were evaluated. Carbon fixation in the photosynthetic metabolism of cowpea plants was reduced by accentuated water deficit, regardless of the genotype. The low stress severity was indicated by the lack of effects on chlorophyll fluorescence, indicating that the reduction in the rate of carbon assimilation was due to the stomatal effects. The irrigation with 80% of ETc can be used in the cultivation of the respective cultivars, but with small losses in the production. Among the genotypes, 'BRS Marataoã' stands out with respect to yield, with higher values for weight of pods and green beans.
