Final answer:
The three main types of water treatment processes used to treat boiler feedwater are filtration, disinfection, and tertiary treatment.
Step-by-step explanation:
There are three main types of water treatment processes that can be used to treat boiler feedwater:
- Filtration: This process removes small particles from the water by passing it through layers of sand, gravel, and charcoal.
- Disinfection: After filtration, the water goes through a disinfection process to remove or destroy harmful materials and organisms. This may involve treatments such as chlorination, ozonation, or ultraviolet disinfection.
- Tertiary Treatment: This is an additional step used to further clean the water before being discharged into a sensitive ecosystem. It may involve processes like chemical dosing, advanced filtration, or biological treatment.
