“…In addition to less energy efficient, conventional desalination processes have enormous impact on marine line and environmental in terms of volume of brine rejection and CO 2 emissions. It is estimated that the brine rejection will increase to 240 km 3 and emission will be approximately [57][58][59][60][61]. The impact of conventional desalination processes on energy and environment can be judged by the developed risk matrix as shown in Table 1.…”

The expansion trend of current desalination processes is expected to boost brine rejection to 240 km 3 and CO 2 emission to 400 million tons per year by 2050. This high brine rejection and CO 2 emission rates are copping COP21 goal, maintaining temperature rise below 2°C. An innovative and energy-efficient process/material is required to achieve Paris Agreement targets. Highly efficient adsorbent cycle integration is proposed with well-proven conventional desalination processes to improve energy efficiency and to reduce environmental and marine pollution. The adsorbent cycle is operated with solar or low-grade industrial waste heat, available in abundance in water stress regions. The proposed integration with membrane processes will save 99% energy and over 150% chemical rejection to sea. In case of thermally driven cycles, the proposed hybridization will improve energy efficiency to 39% and will reduce over 80% chemical rejection. This can be one solution to achieve Paris Agreement (COP21) targets for climate control that can be implemented in near future.

“…Numerous studies have evaluated the environmental impact of reject brine disposal on soil, groundwater and marine environment. The surface discharge of reject brine from inland desalination plants could have negative impacts on soil and groundwater (Rao et al, 1990;Mohamed et al, 2005;Al-Faifi et al, 2010). Other researchers have highlighted the impact of reject brine composition and conditions on marine life (Lattemann and Hopner, 2005;Sadhawani et al, 2008).…”
