When early testing of the water retention and purification system developed at ACP Sales (formerly Retaw) produced some unexpected results, the SME knew they needed an expert to investigate this problem further.

APR.Intern knew that the new state-of-the-art Fluids Lab at the University of Sydney would be perfect to further design, test and optimise Retaw’s SDU’s operating parameters. So honours student, Scott Manning, and his supervisor, Dr Federico Maggi, were matched to tackle the problem.

Scott constructed a laboratory model to simulate the real-world conditions that SDU operated under. The ability to regulate the water flow rates allowed different rainfall scenarios to be investigated, and then by varying the concentration and type of contaminants, SDU’s efficiency could be tested.

“The APR.Intern program facilitated research which would have been difficult to conduct in private enterprise,”

“The outcomes of this project have shown us that there is ample room to conduct further research. And as such we engaged Cate and her team to find us another stellar intern,”
