TCEQ defines "complete treatment" as a sequence of processes that includes which of the following?

"Complete treatment" as defined by TCEQ refers to a comprehensive set of processes necessary to ensure that water is safe for consumption and meets regulatory standards. This includes the initial steps like pretreatment, which prepares raw water for further processing, and a disinfection process that is crucial for removing pathogens and ensuring safe water quality.

Pretreatment disinfection is essential in water treatment because it involves the application of chemical or physical processes to destroy or inactivate harmful microorganisms. This step is fundamental since it directly impacts the effectiveness of subsequent treatment stages and helps in maintaining the safety and quality of the water supply.

While evaporation, desalination, and boiling are important processes in specific contexts of water treatment, they do not encapsulate the full definition of "complete treatment" as defined by TCEQ. Each of these methods serves particular purposes but does not represent the complete sequence of processes that is necessary for comprehensive water treatment.
