Final answer:
Stills, sterilizers, and similar equipment that produce waste should be connected to the sewer to ensure safe and appropriate waste disposal.
Step-by-step explanation:
Stills, sterilizers, and similar equipment that produce waste should be connected to the sewer. This is important to ensure that hazardous waste is properly handled and doesn't contaminate the environment or pose a health risk. Large items such as plastic bottles and other debris are removed by a bar screen at a wastewater treatment plant, to prevent damage to the equipment. If stills and sterilizers were vented to the atmosphere or if they merely had interceptors without connection to the sewer, they could release hazardous material into the environment. A control system is vital for monitoring the processes, but on its own, without being connected to the sewer, it would not suffice for appropriate waste disposal.
During wastewater treatment, the removal of large debris by a bar screen at the treatment plant is only the first step. To address the potential environmental impact of stills and sterilizers, proper infrastructure and processes must be in place. Connecting these equipments to the sewer ensures that the waste goes through the same treatment as other urban waste, preventing the contamination of the environment and protecting public health.
