Activated sludge treatment is aerobic, while trickling filter treatment is anaerobic. T. F.

Anaerobic wastewater treatment methods are advisable as long as the wastewater has a relatively low BOD. T. F.

SOx and NOx are the main causes of acid rain. T. F.

Coal combustion is a cause of acid rain, which does not occur to a significant degree with the combustion of most natural gases, although both contribute to the greenhouse effect. T. F.

To remove particles from gases, methods such as destabilization and colloid coagulation can be used. T. F.

CO2, CH4, and water vapor, among others, play a role in the greenhouse effect. T. F.

Reducing the nitrogen content in fuels would significantly decrease NOx emissions into the atmosphere during combustion. T. F.

Activated sludge treatment is primarily used to reduce biodegradable organic matter in water. T. F.

To remove salts/ions dissolved in water, chemical precipitation methods can be used. T. F.

Sludge treatment serves to stabilize it and reduce its volume so that it can be properly managed. T. F.

Low-cost treatments for the removal of organic matter have the same principle as conventional municipal wastewater treatment plants. T. F.

Primary treatment in a wastewater treatment plant reduces BOD values ​​and suspended solids content, but not nitrate and phosphate levels. T. F.

Primary treatment primarily serves to remove approximately 60-70% of suspended solids and around 30-35% of biodegradable matter. T. F.

Low-cost treatments primarily remove suspended solids and biodegradable organic matter, as they are biological methods, only slightly reducing the content of non-biodegradable organic matter. T. F.
