“…Turek [9] studied a counterflow two-stage ED seawater desalination system and reported energy and cost numbers. Ryabtsev et al [26] implemented a two-stage desalination system. The first stage was operated under a constant current density, and the second stage was operated under a constant voltage.…”

“…Annual global child mortalities (younger than 5 years) are associated with water-and sanitation-related diseases, most of which are preventable through suitable water treatment [4]. Approximately 3% of the Earth's water is fresh, less than 1% of which is usable by humans [5]; therefore, a promising approach to reduce water scarcity is to separate salt from sea and inland saline water in a process called desalination.…”

Reverse osmosis (RO) has been widely utilized in water reclamation plants and produces a concentrated brine (or reject) stream as a by-product. RO concentrates (ROC) contain vast quantities of salts and dissolved organic matter, such as biomass and humic-like substances, which hinder biological wastewater treatment (such as biological nitrogen removal). In this study, we cultivated granular sludge in an aerobic sequencing batch reactor to treat municipal wastewater with an organic loading rate of 2.1-4.3 kgCOD/m 3 day at room temperature (25 • C), and remove total dissolved solids (TDS) from ROC by biosorption, with aerobic granular sludge as a novel biosorbent. The results of the kinetic experiments demonstrated that TDS removal by aerobic granular sludge was more rapid than that by other coagulants and adsorbents (i.e., calcium hydroxide, polyaluminum chloride, activated sludge, powdered activated carbon, granular activated carbon, and zeolite) under optimal treatment conditions. The biosorption of TDS on the aerobic granular sludge was well-modeled by the Lagergren first-order model, with a maximum biosorption capacity of 1698 mg/g. Thus, aerobic granular sludge could be effective as a regenerable biosorbent for removing the TDS in ROC from municipal wastewater.

“…Most of the earth surface is covered by water, which is in the form of the oceans, seas and ice in the poles. However, only 1% of this water, which is in the form of surface or underground water, can be used by human beings without being desalinated (1). The water of the oceans and seas is salty and thus not directly utilizable.…”

Growth of population, increasing urbanization and industrialization, and the rather limited natural resources of potable water leading to serious deficits of freshwater in many regions in the world specially in middle east and golf area. Current water desalination techniques are energy intensive leading to inhibit the wide use of current sea desalination techniques. In this research a lab scale pilot was introduced using a special electrolysis circuit and vibrator producing a square wave powered by solar energy to decrease 35 % of the total dissolved salts/hour in sea water samples.
