We realize that the direction and scope of the research work might change due to a myriad of factors.
Yet, below are some of the future challenges that we see right now. They are not definite - – but perhaps
meant to be a guide to tell where we left off and where the future team might be headed to.
We see that the future team might perhaps be playing with the combinations of the following:
...
Currently, the raw water entering the system is mixed with the concentrated kaolin clay. The
combination of the two ensures that the influent turbidity is at 100 NTU. Yet, it was suggested that that
team might switch from using clay to experimenting with natural organic matter (NOM) to simulate realfield conditions for the water treatment plants. The influent turbidity shouldn't shouldn’t change; nevertheless the
chemical makeup of incoming water might change other parameters in the treatment system.
...
Presently, the team uses floc blanket - – a system of suspended flocs - in its operations. However,
again, the water treatment plants based off of the AguaClara design do not have a floc blanket at all.
Therefore, to mimick these conditions, the team might perhaps be testing the performance of the plate
settlers without the floc blanket. The absence of floc blanket should, again, change some parameters and
consequently, the performance.
