1 Membrane Filtration Units for Industrial & Domestic Applications We Care Our Customer
2 Membrane Filtration Applications Ultra filtration Membranes - Removal of Turbidity, Bacteria and Viruses, with Pre-filtration and Post filtration other contaminants can also be removed.Reverse Osmosis Membranes - Removal of Salts and other ions.

14 Three paths to fresh water. KSB provides reliable solutions to support all three standard methods of extracting fresh water from the sea:1. RO (Reverse Osmosis) pumps seawater at very high pressure through selectively permeable membranes, separating salts from the water.2. MSF (Multistage Flash) is a rapid evaporation process, in which seawater is flashed-heated into steam and condensed.3. MED (Multiple Effect Distillation) passes seawater throughevaporators in multiple stages which is systematically condensed at low temperatures and pressures.Whatever method is applied, KSB is able to leverage extensiveexperience in the energy field to optimize operations, maximize performance and ensure the lowest costs for energy and maintenance.

23 RO - Fouling / Scaling Fouling Types Scaling from Hardness Salts Scaling by SilicaFouling by Metal OxidesPlugging by suspended solidsBiological foulingScalingThe deposition of sparingly soluble salts onto the membrane surface and / or feed channel materialScaling occurs primarily in the down stream elements because of the high concentrations existing in this portion of the RO systemCommon scalants include Calcium Sulphate, silica, and Calcium Carbonate
