Application of membrane technology in the process of preparation of drinking water

Membrane water treatment processes are becoming very important in recent years. Process is based on existance of membrane which divide the feed stream to permeate which contain parts of materials that can pass through the porous membrane and retentate whose components are retained in the pores of the membrane. Membranes can be inorganic and organic origin (organic polymers). Membrane processes used in water technology are: microfiltration, ultrafiltration, nanofiltration and reverse osmosis. Membrane processes have great importance in removing iron, manganese, ammonium, organic matter and arsenic which often in the waters of the eastern Croatia exceeds the limit.
