“…Another hybrid desalination process should be used as a post-treatment for the gas hydrate (GH) process to produce fresh water to improve water quality. Reverse Osmosis (RO) uses GH to make freshwater that meets design specifications, concentration and drinking water regulations [188]. From the standpoint of the RO process, the GH process is one of the pretreatment options for reducing the salinity of saltwater.…”

Innovating methods for treating industrial wastewater containing heavy metals frequently incorporate toxicity-reduction technologies to keep up with regulatory requirements. This article reviews the latest advances, benefits, opportunities and drawbacks of several heavy metal removal treatment systems for industrial wastewater in detail. The conventional physicochemical techniques used in heavy metal removal processes with their advantages and limitations are evaluated. A particular focus is given to innovative gas hydrate-based separation of heavy metals from industrial effluent with their comparison, advantages and limitations in the direction of commercialization as well as prospective remedies. Clathrate hydrate-based removal is a potential technology for the treatment of metal-contaminated wastewater. In this work, a complete assessment of the literature is addressed based on removal efficiency, enrichment factor and water recovery, utilizing the gas hydrate approach. It is shown that gas hydrate-based treatment technology may be the way of the future for water management purposes, as the industrial treated water may be utilized for process industries, watering, irrigation and be safe to drink.

Hydrate‐former selection is important for achieving high water recovery and impurity removal efficiencies in hydrate‐based water treatment. This study presents thermodynamic approaches for selecting a hydrate former suitable for water treatment. Here, carbon dioxide (CO2) and 1,1,1,2‐tetrafluoroethane (HFC‐134a) were investigated as hydrate formers. Simulated studies of the hydrate formation by four formers were conducted at different NaCl concentrations (0.00, 1.75, and 3.50 wt%) to predict the phase‐equilibrium conditions. A commercial software (CSMGem) was used for the calculation of the hydrate‐phase equilibrium of CO2. The Hu–Lee–Sum (HLS) correlation predicted the three‐phase equilibrium of CO2 and HFC‐134a. The results indicated that HFC‐134a is a good candidate for water treatment using gas hydrates. The phase equilibrium results calculated based on the HLS correlation and the CSMGem software confirmed the experimental results obtained using an isochoric method. The predicted thermodynamic properties provide essential information for the process design in water treatment applications.
