Site: Pond 1 and Pond 2

Treated water from C2 outlet enters the pond.

It has plants such as duckweed, tadpoles and fishes living in the waters. The fishes “clean up” the water further because they feeds on the microorganisms living in the pond. The duckweeds and the mangrove plants present help to take up any unwanted nutrients in the water. Duckweeds are unable to thrive in water with high acidity. Thus, it proves the pH value of the pond falls within the acceptable range.



Comparing other parameter (indicating pollution) values of the pond to the grease tap, we find that the values have dropped significantly (refer to Table 2). This proves that the water treatment system has come across effectively.
