Waste Water Collection
The first step in the waste water treatment process is the collection of waste water. Waste water can come from a variety of sources, including homes, businesses, and industrial facilities. In many communities, waste water is collected through a network of underground pipes that lead to a central treatment plant. In some cases, waste water may be collected through septic tanks or other on-site treatment systems.
Pre-Treatment
Before waste water can be treated, it must first undergo pre-treatment. During this stage, large objects such as rocks, sticks, and trash are removed from the waste water. This helps to prevent damage to the equipment used in the treatment process. In addition, grit and sand are removed from the waste water to prevent damage to pumps and other equipment.
Primary Treatment
After pre-treatment, the waste water moves on to primary treatment. During this stage, the waste water is allowed to settle in large tanks. Solid materials, such as human waste and food scraps, sink to the bottom of the tank, while lighter materials, such as oil and grease, float to the top. These materials are then removed from the waste water and disposed of properly.
Secondary Treatment
Following primary treatment, the waste water moves on to secondary treatment. During this stage, the waste water is treated with microorganisms that break down organic material in the water. This process is known as biological treatment. The microorganisms are added to the waste water in large tanks called aeration basins. The waste water is then mixed with air to provide the microorganisms with the oxygen they need to survive. As the microorganisms consume the organic material in the waste water, they reproduce and multiply.
Waste water treatment plants are crucial for ensuring the health and safety of a community by removing contaminants from the water supply.
