The relationship between fouling thermal resistance in a plate heat exchanger and water quality parameters such as iron
total bacteria
pH
dissolved oxygen
turbidity and conductivity in the Songhua River water was investigated.Results show that the value of the fouling thermal resistance in the plate heat exchanger is lower than that of Tubular Exchanger Manufacturers Association (TEMA)
and the natural cooling water has no induction period.pH and dissolved oxygen influence the iron corrosion rate and total bacteria
which affects the turbidity and conductivity.All these parameters have considerable effects on the heat transfer performance in the initial period
and then the effects are less.There exists synergetic effects from different fouling causes
and the fouling can be inhibited by reducing the amount of dissolved oxygen and total bacteria.
