Humidification–Dehumidification (HDH) Desalination and Other Volume Reduction Techniques for Produced Water Treatment

Desalination and Water Treatment

Electrochemical characteristic parameters such as diffusional permeability, ion transport number, fi xed charge concentration and electrical resistance for a regenerated cellulose/polypropylene-supported membrane (RC/PP sample) in contact with NaCl solutions at different concentrations were determined. The effect of the polypropylene support on mass and charge transport was estimated by compari...

Experimental Validation for Two Stages Humidification- Dehumidification (hdh) Water Desalination Unit

This paper demonstrates the preliminary experiments for two stage water desalination by humidification-dehumidification HDH process. An experimental set-up consists of two stages of closed air humidification dehumidification units. In this design, the saline water was heated by evacuated tube solar water heater integrated with electrically heated tank. A series of tests were performed in outdoo...

Forward osmosis: Novel desalination of produced water and fracturing flowback

Treatment and reuse of oil and gas (O&G) production wastewater in a cost-effective and environmentally sound manner is critical for sustainable industrial development and for meeting stringent regulations. High salinity, free and emulsified hydrocarbons, silts and clays released from producing formations, and process additives common in O&G drilling wastewater render many conventional treatment...

Inorganic Membranes: Preparation and Application for Water Treatment and Desalination

Inorganic membrane science and technology is an attractive field of membrane separation technology, which has been dominated by polymer membranes. Recently, the inorganic membrane has been undergoing rapid development and innovation. Inorganic membranes have the advantage of resisting harsh chemical cleaning, high temperature and wear resistance, high chemical stability, long lifetime, and auto...
