One of the important essences of distributed wastewater treatment system integration is to reduce the total treatment flow rate by lowering unnecessary stream mixing amount as much as possible. Based on this insight
a heuristic method is presented for design of distributed wastewater treatment network (WTN) of single contaminant with maximum inlet concentration constraints. Firstly
an initial network is developed based on the precedence order of treatment units and the allocation of streams to treatment units obtained by using the heuristic rules proposed. The final design can then be obtained with mass and flow rate balances. In the design procedure
the following factors will be used simultaneously: heuristic rules proposed
mass and flow rate balances
determination of the pinch point and maximum inlet concentration constraints. The results of a few literature examples show that the designs obtained with the proposed method are comparable to that obtained with mathematical programming approach. However
the proposed method is simple and of clear engineering insight.
