Economics and Energy Consumption of Brackish Water Reverse Osmosis Desalination: Innovations and Impacts of Feedwater Quality

Jeffrey L. Pearson et al.

Summary: Brackish water desalination using the reverse osmosis process has been widely adopted globally, with a range of capital costs and operating costs depending on capacity and water quality. The trend shows that as plant capacity increases, operating costs decrease, but there is variability based on pre- and post-treatment complexity. The presence of high salinity feedwater can lead to increased costs and energy consumption, which can be mitigated with energy recovery systems.

Fouling control in reverse osmosis for water desalination & reuse: Current practices & emerging environment-friendly technologies

Asif Matin et al.

Summary: RO technology is increasingly used for seawater desalination and wastewater reclamation, but fouling of membranes remains a challenge. Various eco-friendly techniques for membrane fouling control are being investigated, including bioflocculation and osmotic backwashing. Fundamental studies are needed to optimize these processes for potential integration into RO plants.

Techno-economic assessment of electrodialysis and reverse osmosis desalination plants

Muhammad M. Generous et al.

Summary: The study compares the economic costs of electrodialysis (ED) and reverse osmosis (RO) desalination methods, finding that under certain salinity conditions, ED has lower costs and is able to handle highly saline water. A sensitivity analysis is conducted to identify key parameters affecting cost variations.

Comparison of Desalination Technologies Using Renewable Energy Sources with Life Cycle, PESTLE, and Multi-Criteria Decision Analyses

Huyen Trang Do Thi et al.

Summary: Desalination is expanding globally as an effective solution to the drinking water shortage, but it poses environmental and health consequences. This study investigated the efficiency of desalination technologies with different energy sources using various assessment methods. Results showed that RO combined with renewable energy provided significant benefits in terms of human health, ecosystem quality, and emissions categories.

Future global urban water scarcity and potential solutions

Chunyang He et al.

Summary: Urbanization and climate change are exacerbating global urban water scarcity, with the number of people affected projected to increase significantly by 2050, particularly in countries like India. Large cities and megacities will be most severely affected, and while infrastructure investment can help alleviate water scarcity, potential environmental trade-offs must be carefully considered.
