D First of all, a facultative pond has an aerobic layer in the upper portion, and an anaerobic layer in the lower portion of the pond. The aerobic layer contains oxygen, while the anaerobic layer does not. This question is regarding the upper aerobic layer. In the upper layer, algae uses sunlight as a source of energy to consume carbon dioxide in the wastewater to produce oxygen.
This process is called photosynthesis, which provides oxygen to the microorganisms to treat the wastewater. During the day, with the presence of sunlight, this process increases oxygen in the pond. Towards the end of the day, there is a lot of oxygen available due to the algae. In contrast, a different reaction occurs at night because of the lack of sunlight. Oxygen is no longer produced by the algae. Instead, the algae consumes oxygen, and releases carbon dioxide. So, an opposite reaction takes place at night. Therefore, at sunrise, there is less oxygen in the pond because it is consumed by the algae during darkness.
Furthermore, as a new day starts, the oxygen content in the wastewater increases again because the algae is using the sunlight to consume carbon dioxide and release oxygen. To clarify, this cycle repeats itself everyday. During the day, algae releases oxygen. C Dissolved oxygen DO is lowest at sunrise because the algae consumes oxygen and releases carbon dioxide during night-time and the dark, early morning hours. This process is called respiration. Without the presence of sunlight, the oxygen in the pond becomes depleted due to the algae. We briefly discussed this earlier, in the answer to Question 1. However, when the sun starts to rise, the algae will begin to use the sunlight to consume carbon dioxide and release oxygen. This increases the oxygen level in the pond. At the end of the day, there is a lot of oxygen available. This process is called photosynthesis. In contrast, at night, algae consumes oxygen. When this ratio increases, it means that the acidity in the digester is increasing, which is a bad sign.
In general, you want to avoid an acidic environment in the digester because it leads to upset. Otherwise, we will encounter operational issues.
