The optimization of a multi-generation system which represents the integrated dual-purpose desalination plant and low-scale absorption refrigeration is addressed. A nonlinear mathematical programming model that integrates natural gas combined-cycle, multi-effect distillation plant, series flow double-effect water-lithium bromide system, water heater, developed based on first-principle models. i...

Capacitive De-Ionization (CDI) is becoming a suitable alternative for desalination. The low cost of the materials required and its reduced energy consumption can be critical factors for developing this technique. CDI technology does not require a high-pressure system and the energy storage capability of CDI cells allows it to be reused in other CDI cells, thus minimizing consumption. The goal o...

This investigation studies desalination powered by wind and solar energy, including a study of a configuration using PVT solar panels. First, a water treatment was developed to estimate the power requirement for brackish groundwater reverse-osmosis (BWRO) desalination. Next, an energy model was designed to (1) size a wind farm based on this power requirement and (2) size a solar farm to preheat...

The mining industry is facing problems of clean production in terms of mineral processing, pollution, water consumption, and renewable energy. An interesting outlook can be to combine the mining industry with membrane-based desalination in the logic of mining from the sea. In fact, several of the drawbacks found in both mining and desalination can be minimized or overcome, which includes hinder...

Accessible fresh water resources for drinking and usage are very limited in our world. Furthermore, these gradually decreasing due to climate change, industrialization, population growth. Despite the ever-increasing need water, inadequacies have made it critical develop alternative utility production methods. Desalination, one of most important alternatives supply, is on rise a global scale. De...

Reverse osmosis is the leading technology for desalination of brackish water and seawater, important solving growing problems fresh supply. Thermal technologies such as multi-effect distillation multi-stage flash still comprise an portion world’s capacity. They consume substantial amounts energy, generally obtained from fossil fuels, due to their low efficiency. Hybridization a strategy that se...

In this study, optimization of Qeshm power and water desalting cogeneration plant has been investigated. The objective functions are related to maximizing exergetic efficiency and minimization of exergoeconomic and exergoenvironmental parameters. Also, the integration of RO desalination with the existing plant has been evaluated based on these analyses. This plant includes two MAPNA 25 MW gas t...

Salt crystallization is one of the most important reasons for the decay of historical objects. A well known example is the historical city of Venice in which there is a lot salt decay. Reducing salt contamination is important for conservation of old historic buildings. Therefore often desalination treatments are done. The desalination of non-movable objects, like buildings, is usually made thro...

This paper focuses on a Hybrid Process that uses feed salinity dilution and osmotic power recovery from Pressure Retarded Osmosis (PRO) to achieve higher overall water recovery. This reduces the energy consumption and capital costs of conventional seawater desalination and water reuse processes. The Hybrid Process increases the amount of water recovered from the current 66.7% for conventional s...
