Abstract
The aim of this study is to apply electrolysis in waste water treatment focusing on removal of total suspended non-metal solids(TSS). Relations among applied voltage, current, area of electrodes and distance between electrodes were quantified. Two experimental tanks including water re-circulating type and fixed batch type were set up and amount of waste water were both 100 liter. Electrodes were made from stainless steel. 6 plates of 1.4m x 1cm x 1mm and 4 plates of 60cm x 1cm x 1mm were used in the re-circulating and fixed batch tanks, respectively.
The removal rate at the first 10 minutes for the waste water at 500μS/cm EC and initial TSS of 200-500 ppm in the re-circulating tank was about 30-40 %. For the waste water at 250-750μS/cm EC and initial TSS of 500 ppm, the highest removal rate at the first 10 minutes was 56.7 %. The TSS removal rates in direct relation to the EC values of the waste water. The removal rate at the first 10 minutes for the waste water at initial TSS of 200-500 ppm and 2 mS/cm EC in the fixed batch tank was 40-50 %. Compare both systems using waste water at 750μS/cm EC and initial TSS of 500 ppm, the removal rate for the fixed batch type at the first 20 minutes was less than the re-circulating type. However, the situation reverse after 1 hour of treatment. The final TSS for the fixed batch type and re-circulating type treatments were 40 and 100 ppm, respectively.
