WOM412 Water treatment processes
This unit is designed to enable the learner to develop their understanding of the principles and processes used to produce drinking water.
Objectives
By the end of this course you will be able to:
- Describe how water treatment processes have developed in response to the incidence of waterborne diseases and other key events and developments.
- Explain how the key quality parameters influence the method, operation and choice of water treatment processes to make water potable.
- Explain the features and operations of the main types of screens and strainers used in water treatment.
- Describe typical chemical dosing systems used in water treatment in terms of the type of pumps and control systems used.
- Explain the key parameters and values which must be optimised in the coagulation process, including any other agents that may be used to affect the process.
- Describe the different types of plant and processes used in water clarification and the factors that influence the choice of process used.
- Describe typical problems which can occur in the clarification process and the corrective actions to resolve them.
- Describe the different types of plant and processes used in water filtration and the factors that influence the choice of process used.
- Describe typical problems which can occur in filtration processes and the corrective actions to resolve them.
- Describe the different types of chemicals and processes used in water disinfection and the factors which could influence the choice of process.
- Describe the chemicals and processes involved in the dechlorination of water.
- Describe typical problems which can occur in pH correction processes and the corrective actions to resolve them.
- Explain the sources of arsenic in drinking water, reasons for its removal, and the processes used to remove it.
- Describe the function and mechanisms of sludge treatment in water treatment works.
- Describe typical problems that occur in the sludge treatment processes and the corrective actions to resolve them.
