Despite the current economic turmoil the need for good quality drinking water continues relentlessly. In the last eight years 11,825 reverse osmosis (RO) plants have come on line with a combined output of 25 million m3/d. Although large seawater plants take most of the ‘desalination news, awards and headlines’, a large number of small and medium sized plants (requiring less energy) are being commissioned that use other water sources. Recent data shows that some 8,500 of these systems are… 

Long-Running Comparison of Feed-Water Scaling in Membrane Distillation

Examination of the system performance, water recovery, scale formation, and saturation index of a lab-scale vacuum membrane distillation in long-running test runs approaching 200 h implies that longer times are needed for MD fouling experiments, and provides further scaling-resistant evidence for MD.

Antiscalants in the Process of Reverse Osmosis: Antiscaling Mechanism and Modern Problems of Application

Despite the available long-term experience in the practical application of antiscalants for preventing the depositions on membranes during the reverse osmosis of sparingly soluble inorganic compounds
