Efficiency research of laundry waste Water treatment by dissolved air flotation method

Abstract

To protect environment from industrial pollution, are creating strictly requirements tor waste water treatment. The purpose of research is to establish optimal ratio from saturated liquid anil laundry waste water, than achievable the highest efficiency results. Results of research were carried out in 2008. For research was chosen's laboratory and experimental models. For experimental model was chosen JSC "Traidenis" flotation wastewater treatment system. The best's ration of wastewater and saturated liquid in laboratory model were 4:1 and 1:1, than continuous time in floatation chamber is 5 minutes. Repeatedly analysis done in experimental model confirmed laboratory model results. The optimal wastewater and saturated liquid ratio was 4:1. By this ration was achieved 96 % efficient by ChDS removal.
