Problem
Hong Kong waters are dirty.
Question
How can we clean the dirty water by using biology? By clean we will be using the World Health Organisation's Guidelines for safe recreational water environments
level of intestinal enterococci per 100 ml
The level of toxic species of algae that occur in the marine environment
pH levels
E.coli levels
Methodology
We will test 5 marine species which are know for cleaning water all at the same maturity and the same amount of the species and the same water from one large tank will be divided into 5 other tanks where the water amount will be equal and equal amount of time will be given in this research
Experiment, Measurements, Observation (biology)
The species: Sponges, sea cucumber, mussels, oysters and Cleaner Shrimp
we will measure the levels of pH, E.coli, toxic species of algae and intestinal enterococci before we put the species in. And we will measure the same things again after a certin period of time
Conclusion
We will draw a conclusion by making a table comparing how the levels of pH, E.coli, toxic species of algae and intestinal enterococci changed in each tank after the species where added. And we will see which species got the closest to the WHO standards.
Extrapolation and scaling of the solution
If we can find out which species does what well we could implement this around Hong Kong waters.
