Wastewater

The first step of the water treatment process is...

• Coagulation

• Disinfection

• Filtration

• Sedimentation

• Flocculation

A slimy mud-like substance is known as...

• Floc

• Coagulant

• Sludge

• Turbidity

What does turbidity measure?

• The amount of chemicals in water.

• The amount of fish in water.

• The clarity of water.

• The amount of pathogens in the water.

Eutrophication is when...

• a body of water gets too much nutrients.

• a body of water gets overpopulated with fish.

• a body of water gets polluted by point-sources.

• the amount of water decreased from a lake or pond.

If a lake has very high turbidity, it means the water is very clear.

• True

• False

Low turbidity means that the water is...

• acidic

• basic

• clear

• murky

Algae blooms are an abundance of harmful organisms caused by...

• Too much sunlight.

• Too much nutrients from agricultural runoff.

• Water that is too cold.

• Water that is too warm.

What does effluent mean?

• A body of water has too much nutrients.

• A body of water is overpopulated with pathogens.

• Sewage and other wastes disposed into a body of water.

• A body of water is too acidic or basic.

Water that is "potable" means...

• the water has been treated.

• the water has been desalinated.

• the water is considered to be wastewater.

• the water is safe to drink.

Water flows through a filter designed to remove the particles form.

• Agitation

• Coagulation

• Filtration

• Flocculation
