“…However, this cannot be implemented for irrigation water treatment directly because microbial population increases and hence can cause biofouling, leading to blockage of the pipelines. The fixed cost of these processes would be high; hence, it reduces scalability (Kausley et al, 2019).…”

The present study focuses and assures the need for pesticide degradation from various water bodies used for irrigation and the available technologies to treat them effectively. A thorough review of the literature is done on pesticide residues present in various irrigation water sources like rivers, groundwater, river sediments, and soil which signifies the existence of pesticides in the ecosystem.This indicates the severity of water pollution due to various sources around and their adverse effect on the ecosystem. However, several technologies are available to treat these pesticides based on the classification. A Cross comparison between the technologies is done to determine the efficient technology for the treatment of irrigation water.

“…It is expected that by 2025, nearly 2 billion people will live in absolute water scarcity conditions and two-thirds of the world’s inhabitants could experience water stress, turning this crisis into one of the greatest challenges to overcome for the 21st century human development. Consequently, individual countries and regions must urgently address the critical issues posed by water stress through water management strategies, technologies, and regulations that address water availability, demand, treatment, discharge, and socioeconomic issues. , Decision-making approaches for water management must adopt a multiobjective framework through which it is possible to model the water systems, supply, demand, technologies, sustainability, and socioeconomic objectives and constraints. Solving water optimization problems in real scenarios becomes subjective according to the demands of each stakeholder, and identifying an optimal solution is a complex task.…”

This work presents an optimization model for macroscopic water networks, considering wastewater treatment, rainwater harvesting, allocation, and recycle/reuse. Given the pressing problem of water scarcity the world faces, it is important to address it while considering all of the stakeholders from various sectors. Furthermore, several intertwining objectives must be considered, including water resource conservation, social progress, and economic benefits. A systematic optimization approach is proposed to solve this problem. Trade-offs are established among the unsatisfied demand for domestic users, system profit, and the dynamic level of water wells. A superstructure is developed to embed configurations, considering domestic and industrial users. The users' water demands are seasonally dependent. Treatment options are considered to render the water in acceptable quality for its end use. The system has different storage devices that can be introduced at different locations in the targeted region. The solution of the optimization formulation provides a characterization of the design and operation of the macroscopic water system while providing the decision-makers with rigorous trade-offs and synergistic opportunities.

“…Desalination of brackish water using reverse osmosis (RO) has been one of the ultimate effective methods for addressing water scarcity (Pan et al 2020). Unfortunately, this technology is costly, less acceptable, and unaffordable for many countries (Kausley et al 2018). It is an extensive energy process as the range for desalination of brackish water using the RO process is from 17 to 27 bar (Kondili 2012) which is considerably high and thus can result in high capital costs, as well as a high level of labor competence to manage such a huge infrastructure (Shenvi et al 2015).…”

Water purification from brackish water sources has been acknowledged as one of the most promising ways in producing drinkable water in water-scarce areas. In this study, an ultra-low pressure reverse osmosis (ULPRO) membrane was numerically and experimentally investigated to produce drinking water by the removal of sodium chloride salt which provides further validation of the model from a practical perspective. An enhanced predictive model based on Donnan-Steric Pore Model with dielectric exclusion (DSPM-DE) incorporating the osmotic effects was formulated in process simulation. The feed pressure and concentration were optimized as input variables and interaction between them was observed, while salt rejection and water recovery rate were taken as response attributes. The results obtained on the ULPRO membrane showed that the performance depends on the charge, steric, and dielectric effects. Furthermore, the enhanced model was validated with the experimental data attained from a lab-scale filtration system with good accuracy in the salt rejection and water recovery results. Comparing the enhanced DSPM-DE with the existing solution diffusion model reveals that the enhanced model predicts the membrane performance better and thereby qualifies itself as a reliable model for desalination of brackish water using ULPRO membrane.
