Final answer:
Discharging wastewater directly into nearby rivers is not a part of a factory's control system to prevent the release of wastewater that does not meet discharge standards. Instead, factories use regular monitoring, treatment systems, and proper maintenance of equipment to ensure wastewater meets standards before being released.
Step-by-step explanation:
All of the following would be part of a factory's control system to prevent the release of wastewater that does not meet discharge standards EXCEPT discharging wastewater directly into nearby rivers. An effective control system for wastewater includes:
- Regular monitoring of wastewater quality to ensure that the effluent meets legal and environmental standards before discharge.
- Installation of treatment systems which are designed to remove contaminants and pollutants from the wastewater to a level that is safe for discharge or reuse.
- Proper maintenance of equipment in the treatment plant to ensure its efficient operation and prevention of breakdowns that could lead to untreated wastewater being released.
However, discharging wastewater directly into nearby rivers would be in direct violation of most regulations and standards designed to protect water quality and is not a control measure. Factories are expected to treat wastewater to remove contaminants before it is released back into the natural environment, and point-source pollution regulations specifically outlaw such direct discharges.
