Disolved air flotation) is used in physical \u2013 chemical treatment of industrial wastewater. It is used for removing suspended and floating particles from the waste water (oil, grease, emulsions, etc..). At the exit from device is the product obtained purified water and sewage sludge. The purified water is discharged into the drain or\u00a0 to the further\u00a0 treatment depending on the required level of waste water purification.<\/p>\n<p>Flotation device is in\u00a0 use as an integral part of the device for the treatment of waste water in following industries:<\/p>\n<ul>\n<li>from the food industry (dairy industry, meat industry, slaughterhouse, fruit and vegetables processing, processing of oil, \u2026),<\/li>\n<li>\u00a0the paper industry,<\/li>\n<li>the metal industry,<\/li>\n<li>\u00a0the refinery,<\/li>\n<li>etc..<\/li>\n<\/ul>\n<h2>DESCRIPTION\u00a0OF THE DEVICE<\/h2>\n<p>Otpadna tehnolo\u0161ka voda se, pomo\u0107u ekscentri\u010dne pumpe,\u00a0 odvodi iz spremnika za egalizaciju u ure\u0111aj za flotaciju. Pri tome prolazi kroz cijevni mikser u kojem se vr\u0161i kemijski tretman otpadne vode. Otpadna voda se neutralizira te se u nju dodaju flokulanti i koagulanti. Nakon kemijskog tretmana u otpadnoj se vodi nalazi velika koli\u010dina raspr\u0161enih krupnijih\u00a0 \u010destica tj. flokula. Uklanjanje prethodno navedenih produkata vr\u0161i se pomo\u0107u sitnih mjehuri\u0107a zraka. Mjehuri\u0107i nastaju dovo\u0111enjem vode (s otopljenim zrakom pod tlakom od 3 do 6 bara) u ure\u0111aj za flotaciju, koji se nalazi pod atmosferskim tlakom. Prilikom opisanog procesa dolazi do ekspanzije otopljenog zraka iz vode u obliku mikro mjehuri\u0107a, veli\u010dine 20-40 \u00b5m. Nastali mikro mjehuri\u0107i zraka ve\u017eu se za flokule i zajedno isplivavaju na povr\u0161inu gdje tvore plivaju\u0107i mulj. Mulj se iz reaktora uklanja pomo\u0107u strugala li se ispu\u0161taju kroz konusni otvor, pomo\u0107u komprimiranog zraka. Efluent (pro\u010di\u0161\u0107ena voda) odlazi iz reaktora ure\u0111aja za flotaciju na daljni tretman pro\u010di\u0161\u0107avanja ili u kanalizaciju. Izdvojeni mulj odvodi se u spremnik za mulj ili na strojnu dehidraciju.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_single_image image=&#8221;8148&#8243; img_size=&#8221;full&#8221;][vc_column_text]<\/p>\n<h2>THE COMPONENTS OF THE DEVICE<\/h2>\n<ul>\n<li>circular vertical reactor made of polypropylene,<\/li>\n<li>The inlet eccentric pump,<\/li>\n<li>The multiphase pump for recirculation,<\/li>\n<li>Pipe mixer with equipment for injecting air and chemicals,<\/li>\n<li>Dosing station for chemicals.<\/li>\n<\/ul>\n<p>[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_single_image image=&#8221;8200&#8243; img_size=&#8221;full&#8221;][\/vc_column][\/vc_row][vc_row][vc_column][vc_single_image image=&#8221;8158&#8243; img_size=&#8221;full&#8221;][vc_column_text]<\/p>\n<h2>LEGEND:<\/h2>\n<p>1-Mecanical treatment\u00a02-Equalisation tank\u00a03- The inlet eccentric pump\u00a04-Flotation device\u00a05-Dosing station for coagulants\u00a06- Dosing station for base\u00a07- Dosing station for flokulants\u00a08-Pipe mixer\u00a09-pH regulation\u00a010-Sludge tank\u00a011-Recirculation of drained water\u00a012-Sludge outlet\u00a013-Control box\u00a014- Water connection\u00a015-Power connection\u00a016-Connection of compressed air\u00a017-Building for equipment[\/vc_column_text][\/vc_column][\/vc_row]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[vc_row][vc_column][vc_single_image image=&#8221;8144&#8243; img_size=&#8221;full&#8221;][vc_column_text] FLOTATION DEVICE DAF flotation device (Eng.
