Development of a testing method for efficiency of waste water pumps

The undissolvable handkerchiefs/clothes in water can cause problem for the impellers in the pump. These clothes in huge amounts clog the impeller of the pump so hard, that this could cause damage to the impeller and the pump could stop functioning. So what to do? Either we can stop throwing these things in the pump, which is quite near to impossible, or we need to do something with our pumps. In the framework of the study, different parameters such as diameter of the impeller, the size of the impeller, the spill-over effect of the degree of contamination of water with such clothes on the impellers of the pump etcetera have been discussed and analyzed. The parameters were, moreover, calculated in different ways using different testing methods and test-beds. This, we believe, can help in achieving optimum efficiency for the waste water transportation.
