This separation method requires prior flocculation and coagulation steps. Lamella clarifier is designed to maximize settling efficiency of suspended particles with minimal footprint.<\/p>\n<p><b><br \/>\nDAF (<\/b><b>Dissolved Air Flotation)<\/b><\/p>\n<p>DAF technology is an efficient procedure for the separation of suspended matter (turbidity \/ TSS, algae etc.) from seawater, \u00a0. Dissolved air flotation (DAF) utilizes the property of micro-bubble adherence to suspended solids, increasing the tendency of the particles to float. These micro-bubbles attach themselves to discrete floc particles created in the flocculation process. DAF enables efficient separation of suspended solids, and oil &amp; grease traces, as well as the reduction of organic load. IDE designs a stand alone DAF or DAF in filter, as part of the pretreatment.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Multimedia Filtration (MMF)<\/strong><\/p>\n<p>A multi-media filter (MMF) is used to reduce the level of suspended solids in feed water by filtration \u00a0through several \u00a0granular media, which can include gravel, sand and anthracite. This method is implemented in the majority of desalination plants, and its advantage is low consumption of chemicals and high system sustainability.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Ultrafiltration (UF)<\/strong><\/p>\n<p>Ultrafiltration (UF) is a pressure-driven membrane filtration process. UF is used for separation of suspended solids, colloids, and bacteria. The filtration is achieved by forcing the water to flow through a membrane with a small pore size of approx. 0,02 \u03bcm, which creates a barrier and produces water with high purity and low SDI (silt density index)<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>&nbsp; Mega size desalination plants are often located in regions with challenging feed water quality.
