The COD measurement is limited in that it only determines biodegradable organic matter. T. F.

Reducing the amount of non-biodegradable organic matter is the main objective of primary wastewater treatment. T. F.

Natural waters contain substances due to their solvent capacity and erosive potential, therefore they must be treated before consumption. T. F.

La ausencia de bacterias coliformes en aguas residuales, significa que no existe contaminación por bacterias. T. F.

Tertiary wastewater treatment generates residues in a wastewater treatment plant that are used to make compost. T. F.

The conductivity of wastewater depends on the concentration of ions it contains. T. F.

The biodegradability of wastewater does not depend on the chemical structure of the organic matter. T. F.

Fixed-culture aerobic treatment lagoons or areas occupy land areas of up to 5000 m². T. F.

In grit removal, the settling capacity of wastewater is below that of sand, but above that of organic matter sedimentation. T. F.

In rotary reactors, treating wastewater with biodegradable organic matter reduces energy production and consumption. T. F.

The characteristics that make chlorine one of the most widely used reagents in wastewater disinfection are that it is the cheapest and costs four times as much as other reagents in its family. T. F.

Greenhouse gases contribute to global warming through adsorption and ultraviolet radiation. T. F.

Primary gaseous pollutants have a more severe effect than secondary pollutants. T. F.

Tropospheric ozone is a pollutant that, if it exceeds certain levels, can be very dangerous. T. F.

Carbon monoxide is a poisonous gas that significantly interferes with the supply of oxygen in the blood. T. F.

The selection of the type of equipment used in particle removal depends mainly on the size of the particles. T. F.

One of the most common configurations is an electrostatic precipitator followed by a cyclone. T. F.

The use of bagging effects with flammable or explosive particles is not recommended. T. F.

In plate columns, polluting gases and particles are removed simultaneously. T. F.

High-density landfills require that the waste stored in them be covered with a layer of organic soil daily. F. T.

In the composting of organic waste, the degree of moisture is a parameter that must be controlled. T. F.

To properly manage waste, it is important to know its chemical composition. T. F.

A hazardous waste landfill must be located near an aquifer to discharge the leachate it generates. F. T.

Landfills must be located at a minimum distance from the nearest population centers. T. F.

The geological barrier of a hazardous waste landfill has a minimum thickness of 5 mm. F. T.

Landfills should be considered as a last resort in waste management. T. F.
