The below article is the continuation of the researcher’s study on sewage treatment with the focus on understanding oceans.
1. The process of sewage treatment can be thought of as a “complex form of composting.”
2. “The compost heap which you may have in your garden is like a miniature sewage treatment works.”
3. The centre usually becomes anaerobic as existing oxygen is used up.
4. Closer to the top of the heap aerobic processes take place. Apart from the raw material, the other big difference between a sewage treatment works and a compost heap is that inside a compost heap, temperatures become high – well above 60 °C – which is detrimental to most species of microbes, but in which some can flourish.
Reference for the above 4 points:
Some thoughts on this:
1. Composting is good for gardens so why is it not a thought solution for oceans?
2. Is composting in oceans a natural phenomenon which has slowed down due to pollution and needs a boosting through human efforts?
3. Are there regions in oceans which have turned anaerobic?
4. Is methane produced to a still greater extent in the areas which are anaerobic or are lacking natural composting?
5. Is the temperature increase in oceans attributable to the lack of natural composting or anaerobic conditions?
6. If CO2 in air can heat oceans then can anaerobic oceans heat the air?
