A compression device to compress sponges for foam generation has been developed, which allows standardisation of the process of foam generation using sponges. The foam mass generated as function of concentration of surfactant solution is obtained for each of the three porous sponges investigated: dishwasher sponge, car sponge and audio sponge. For all the sponges investigated 5 presses of the compression device produced all of the available foam from a particular sponge. The porosity and pore size of a dishwasher and car sponge was found to be very similar, an audio sponge was found to have the same porosity but a significantly smaller pore size. It was found that the maximum amount of foam is generated for a 70% concentration of surfactant solution for all of the sponges used. The dishwasher and audio sponges foamability was found to be independent of the hardness of water i.e. concentration …
