Today,on day 45(25/5/2016).We are presenting you our results from day 20 to day 65


Day 40

The odor of our experiment its worse than  the last time due to the presence of hydrogen sulfide (H2S).The lower layer of the sediment its much more darker due to the presence of organic matter.The colour of the water its white-yellow and its different than the last time.



















Day 65

Here we can see that the colour of the water its grey and its different than the last time (DAY 65).Also,the water level its lower than the last time.

We can observe that the colour of the water on the surface layer is white-grey and that means that the microorganismos are dying.
