Technical and economic aspects of industrial laundry wastewater treatment
Journal Title: Civil and Environmental Engineering Reports - Year 2011, Vol 1, Issue 7
Abstract
Three biological methods of laundry wastewater purification were tested, in pilot scale, in Fliegel Textilservice laundry in Nowe Czarnowo. Among tested methods, rotating biological contactor, membrane bioreactor and sponge activated sludge reactor, the last one has been pointed out as optimal for laundry wastewater treatment. Biological treatment of laundry wastewater, assisted by nitrogen addition, phosphorus chemical precipitation and neutralisation, generated purified wastewater with satisfactory quality. Case study of industrial laundry shows that total costs of wastewater utilization may be reduced by 39% and payback period of total investment costs is estimated at 7-8 years.<br/><br/>
