FLOTATION DEVICE

DAF flotation device (Eng. Disolved air flotation) is used in physical – 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  to the further  treatment depending on the required level of waste water purification.

Flotation device is in  use as an integral part of the device for the treatment of waste water in following industries:

  • from the food industry (dairy industry, meat industry, slaughterhouse, fruit and vegetables processing, processing of oil, …),
  •  the paper industry,
  • the metal industry,
  •  the refinery,
  • etc..

DESCRIPTION OF THE DEVICE

Otpadna tehnološka voda se, pomoću ekscentrične pumpe,  odvodi iz spremnika za egalizaciju u uređaj za flotaciju. Pri tome prolazi kroz cijevni mikser u kojem se vrši 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 količina raspršenih krupnijih  čestica tj. flokula. Uklanjanje prethodno navedenih produkata vrši se pomoću sitnih mjehurića zraka. Mjehurići nastaju dovođenjem vode (s otopljenim zrakom pod tlakom od 3 do 6 bara) u uređaj za flotaciju, koji se nalazi pod atmosferskim tlakom. Prilikom opisanog procesa dolazi do ekspanzije otopljenog zraka iz vode u obliku mikro mjehurića, veličine 20-40 µm. Nastali mikro mjehurići zraka vežu se za flokule i zajedno isplivavaju na površinu gdje tvore plivajući mulj. Mulj se iz reaktora uklanja pomoću strugala li se ispuštaju kroz konusni otvor, pomoću komprimiranog zraka. Efluent (pročišćena voda) odlazi iz reaktora uređaja za flotaciju na daljni tretman pročišćavanja ili u kanalizaciju. Izdvojeni mulj odvodi se u spremnik za mulj ili na strojnu dehidraciju.
