An Application of Principal Component Analysis to The Study of Activated Sludge Treatment System Performance Efficiency For the Degradation of Malathion

Imran Hashmi, S. Shahid Shaukat, Moazzam Ali Khan and M. Altaf Khan

Abstract:
The biosimulator system (activated sludge system) have proved to be very effective in the treatment of wastewater containing high content of pesticide and Chemical Oxygen Demand (COD) in terms of organic load and the quality of effluent being obtained after treatment was acceptable for landscape irrigation and for growing plants of ornamental value for commercial use. The biosimulator can be operated without being an aesthetic nuisance at a considerably low Dissolved Oxygen (DO). The efficiency of the biosimulator at high organic load (pesticide inobulated) and the inoculation of strain of Pseudomonas capable of degrading malathion, could be used to minimize time for treating wastewater containing high content of hazardous pesticide.The principal component analysis exposed the groups of correlated variables and their importance in the data structure. MalIN -MalOUT, TMC, MalOUT/MalIN and CODOUT/CODIN were highly correlated with each other and emerged as the variables controlling the first component. DO, pH and retention time governed the second component. The third component of PCA essentially repeated the trend exhibited by the first two components. The presence of pesticides or their metabolites, emphasizes the need for conducting monitoring studies, in order to draw a national picture for overall assessment of the situation.
