• We compare drinking water treatment systems, a NF unit and a conventional treatment. • Sustainable water quality improvement using renewable energy is demonstrated. • Membranes are more efficient than conventional treatment removing micropollutants. • Membranes reject hydrophobic compounds causing

In recent years, reverse osmosis (RO) has grown as an alternative to traditional potable water sources. A major disadvantage of the RO process is the huge amount of brine and its negative impact as a result of its high salinity. This brine is usually discharged to inland water bodies or to the sea a

In this paper, the viability of using micellar draw solutions (DS) for Forward Osmosis (FO) is presented for the first time. Above the critical micelle concentration (CMC) and the Krafft temperature (Tk), the monomers in a surfactant solution aggregate to form micelles, resulting in a relatively cons

This study evaluated the applicability of a modified design vacuum enhanced-multi effect membrane distillation (V-MEMD) for drinking water production with feed solution containing NaCl and CaSO4. The applicability was studied in terms of flux, scale formation and ease of cleaning. A slight flux decline

The present study introduces an attempt for the application of flash desalination technique for small scale needs. An integrated system uses a flashing desalination technique coupled with nano-fluid-based solar collector as a heat source has been made to investigate both the effect of different operati

Desalination generates drinking water and enhances the economic, social, and environmental development of many areas with few water resources, such as parts of the Middle East, North Africa, and southern Europe (such as Spain and Cyprus). Desalination plants may cause environmental impacts in coasta

Recent research reports have underlined reverse osmosis (RO) as the most optimized technology for water desalination related applications. However, implementing this technology to seawater desalination is facing challenges of membrane fouling. This includes membrane biofouling, organic and inorganic

New membranes for forward osmosis (FO) have been made by numerous academic groups around the world. Few of these designs, however, have made it to full-scale production. For two decades, the only FO membrane made on a full-scale production line was a cellulose acetate membrane from Hydration Technol

Forward Osmosis (FO) has many applications in water and wastewater treatment and seawater desalination. In this paper, the FO was suggested for seawater pretreatment to the thermal desalination processes such as Multi Stage Flashing (MSF). The integrated FO–MSF hybrid system was designed to reduce t

A co-generation system producing electricity and freshwater by a solar field driven supercritical organic Rankine cycle (SORC) coupled with a desalination unit is proposed. The proposed system can use parabolic trough solar collectors (among other options) to produce 700 kW thermal energy with temper
