Treatment of wastewater transported by vacuum trucks Available to Purchase

This paper presents the results obtained during the evaluation of a system of stabilization ponds in which exclusively liquids transported by vacuum trucks are treated. The liquids proceed from the emptying of cesspools and from septic tanks and have different characteristics from fresh sewage. Information is provided about the efficiency achieved in the reduction of BOD and faecal coliform bacteria. Comments are made on the results obtained in batch tests to determine the BOD(k) and faecal coliform bacteria (kb) removal constants and they are compared to the values of constants obtained from data about the functioning of the ponds. The conclusion is that a system of stabilization ponds is efficient for the treatment of this kind of wastewater, if it is designed bearing in mind its particular features, and with this purpose a treatment scheme is recommended.
