In this article we will discuss about:- 1. Types of Aerated Lagoons 2. Design of the Aerated Lagoons 3. Advantages. Types of Aerated Lagoons: Aerated lagoons are deep waste stabilization ponds in which sewage is aerated by mechanical aerators to stabilize the organic matter present in the sewage, rather than relying only on photosynthetic oxygen produced by algae. Thus aerated [...]
The following points highlight the ten main factors affecting the construction of facultative pond. The factors are: 1. Site Selection 2. Pretreatment 3. Construction in Stages 4. Multiple Units 5. Pond Shape 6. Embankment 7. Pond Bottom 8. Inlet Structure 9. Outlet Structure 10. Pond Interconnections. Factor # 1. Site Selection: Facultative pond sites should be located as far away [...]
Stabilization ponds are usually classified according to the biological activity that takes place in the ponds as: 1. Aerobic Ponds 2. Anaerobic Ponds 3. Facultative Ponds. 1. Aerobic Ponds (Algae Ponds): The aerobic ponds (also known as algae ponds) are designed to maintain completely aerobic conditions. In these ponds oxygen is supplied by natural surface aeration and by algal photosynthesis. [...]
