“…The main optimizations include: device's design and configuration, thermodynamic design, material selection and so on. In practical MSF applications, using demisters and anti-foam agents to avoid the water's entering in the vapor [20], adding chemicals or on-line ball cleaning apparatus to solve the scaling problem and ensure thermal conversion efficiency for a long-time service [20][21][22],using stainless steel, duplex steel, titanium tubes, nickel alloys and other materials to reduce corrosion of the devices as well as cost of construction [23,24].…”

Water scarcity and pollution pose critical situation in all walks of life.Among the available purification methods,desalination process proves to be a safer and more stable solution for solving this problem. This paper provides an overview of the purification effect of distillation process, along with theprinciples and research progress ofdifferent distillation techniques for small scale drinking water preparation.This paper also analyzes the advantages and disadvantages of each method, as well as proposes an outlook forthe distillation technology on drinking water preparation. This paper also indicates that the removallaw of organic pollutants, especially the volatile organic pollutants during distillation process should attract researchers' attention, whilereducing energy consumption of distillation technology through various means is still the development tendency.

“…In thermal seawater desalination plants, the main technique currently employed to control alkaline scales -such as calcium carbonate (CaCO 3 ) and magnesium hydroxide (Mg(OH) 2 ) -is the addition of antiscalants [2À5]. Their precipitates are soft and readily removed from heat exchanger surfaces by on-line acid washing [6] or sponge-ball cleaning [7,8]. To prevent non-alkaline scale such as calcium sulfate (CaSO 4 ), the maximum top brine temperature is maintained below 120 C. From an economic viewpoint, operating evaporators at higher temperatures enhances performance substantially, provided scale is prevented [9].…”

In mechanical vapor compression (MVC) desalination, high operating temperatures (>120 C) allow for high heat transfer coefficients and reduced compressor size, both of which lower total capital costs. To prevent formation of calcium sulfate scale on high-temperature desalination heat exchangers, the inverse solubility of calcium sulfate requires high sulfate removal. To selectively remove sulfate from seawater, a weak-base anion-exchange resin (Relite MG 1/P) was used. In synthetic seawater, the resin shows high sulfate selectivity. Conveniently, the exhausted resin can be regenerated with concentrated acidified (pH 4) blowdown brine from the desalination heat exchanger. Using the same exhaustion and regeneration times, high desalination concentration factors increase chloride concentrations in the blowdown brine, which allows for slower regenerant flow rates thereby increasing regeneration efficiency and sulfate removal. Using a high concentration factor helps regeneration; however, this must be balanced against the greater tendency to form scale in the desalination heat exchanger. With a fixed concentration factor, high flow rates lower the regeneration efficiency and the extent of sulfate removal. In contrast, low flow rates require larger equipment and more resin, which increases capital costs. For a desalination plant with a production capacity of 1 million gallons per day (MGD) and a concentration factor of 2, the cost of sulfate removal -including all operating and capital costs -varies from $0.246 to $0.356/thous gallon as the maximum brine temperature changes from 140 to 180 C.
