Abstract

Wastewater samples from liquid effluents of a slaughterhouse in the city of Yaounde (Cameroon) was first analyzed and exposed to gliding arc (glidarc) electric discharge to reduce the pollution load. The analyzed results showed high levels of organic pollution parameters (BOD5 = 2000 mg/L, COD = 30544 mg/L) and the presence of a large amount of microorganisms. The UV-Visible spectrum showed an absorbance peak at 663 nm which can be attributed to chlorophyll. A hexane extract of green leaves of senna alata was thus exposed to the plasma to follow the degradation of chlorophyll. After 30 minutes of treatment, reduction rates of 96% and 73% respectively were obtained for BOD5 and COD. The absorption peak disappears and a discoloration rate of 76% was obtained. Microorganisms such as fecal coliforms and fecal streptococci present in large quantities were completely destroyed by plasma after 15 minutes of exposure to the electric discharge. In addition, the decrease in total organic carbon showed that there was mineralization of chlorophyll contained in senna alata. This study shows that the gliding arc plasma is effective in cleaning the wastewater from slaughterhouses and in degrading chlorophyll.
