Hazardous waste originating from private households can be used in composting. T. F.

When defining what waste is, reference is made to it being in a solid state. T. F.

To carry out composting, parameters such as temperature, moisture, the C/N ratio, and the degree of humidity must be taken into account. T. F.

The composition of biogas is always the same in all landfills. T. F.

Gases emitted as a result of hazardous waste incineration must be treated before being released into the atmosphere. T. F.

Waste generated from hazardous waste management is also considered hazardous. T. F.

Wastewater produced by a livestock farm has high BOD and COD. T. F.

Activated sludge treatment is capable of removing all possible contaminants from wastewater. T. F.

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

In low-cost aerobic treatments, lagoons are very deep in order to increase the amount of dissolved oxygen. T. F.

A discharge of hot water promotes the development of organisms present in wastewater (WW). T. F.

After a coagulation–flocculation treatment of wastewater, it is necessary to include a sedimentation step. T. F.

Wastewater with a high organic load can be easily treated by applying a single treatment. T. F.

Trickling filters or green filters are used in the treatment of biodegradable organic matter present in wastewater through the cultivation of microorganisms in suspension. T. F.

In order to reduce the water content of the sludge stream, rotary vacuum filters are more effective than horizontal belt filters. T. F.

Pollution control equipment is designed based on immission concentrations measured for secondary pollutants. T. F.

An adsorbent material can remove any type of contaminant from a gaseous effluent. F. T.

Adsorption is the best method for treating acidic gas emissions. T. F.

The technology that selectively reduces the amount of SOₓ in a gaseous effluent and transforms it into nitrogen is called selective catalytic reduction. T. F.

To manage a hazardous industrial waste by controlled landfilling, it is initially necessary to inert it in order to reduce its potential environmental impact. T. F.
