Risk assessment of ice dams for water diversion projects based on fuzzy fault trees Appl. Water Sci. Pub Date : 2021-01-18 Mengkai Liu, Xiaoxia Dong, Hui Guo
Ice dams are among the important risks affecting the operational safety and water conveyance efficiency of water diversion projects in northern China. However, no evaluation indicator system for ice dam risk assessment of water diversion projects has been proposed. Therefore, in this paper, based on the formation mechanism of ice dams, the risk assessment indicator system and the possibility calculation

Hydrogeochemical status and geoelectrical characteristics of the shallow aquifers of Kalanad Basin, Kasaragod, Kerala, India Appl. Water Sci. Pub Date : 2021-01-17 S. Anoop, C. Ashwathi, V. Haritha Baburaj, Resma S. Pillai
Groundwater demand has increased due to overpopulation and intensive irrigation which resulted in decline of water resources and deterioration of water quality. In this view, a microlevel study was conducted through hydrogeochemical investigation and resistivity survey (VES) in Kalanad river basin, Kasaragod, Kerala. The study aims to determine the spatial variations in physicochemical parameters with

Solar nanophotocatalytic pretreatment of seawater: process optimization and performance evaluation using response surface methodology and genetic algorithm Appl. Water Sci. Pub Date : 2021-01-14 Varghese Manappallil Joy, Shaik Feroz, Susmita Dutta
In reverse osmosis seawater treatment process, membrane fouling can be mitigated by degrading organic pollutants present in the feed seawater. The present study evaluates the effectiveness of employing solar photocatalysis using TiO2/ZnO/H2O2 to pretreat reverse osmosis (RO) feed seawater under solar irradiation. Process optimisation and performance evaluation were undertaken using response surface

Removal efficiency of phenol by ozonation process with calcium peroxide from aqueous solutions Appl. Water Sci. Pub Date : 2021-01-14 Zhila Honarmandrad, Neda Javid, Mohammad Malakootian
Phenol has been introduced as a priority pollutant by the US Environmental Protection Agency. Advanced oxidation processes (AOPs) are one of the most efficient methods for removal of non-degradable organic pollutants in aqueous solutions. The removal efficiencies of phenol and COD under optimal conditions pH = 3, phenol concentration = 5 mg/L, CaO2 concentration = 0.025 mg/L, temperature 25 °C, 1 g/min
