The measure of the amount of salt dissolved in water.
What is salinity?
Using living things to remove contaminants from water
What is bioremediation?
In this step, Wastewater undergoes a biological treatment process where micro-organisms break down organic matter.
What is step 2 in the wastewater treatment process?
You can test this using a thermometer. A high result is a sign of poor water quality.
What is temperature?
These are the highest areas of land on Earth.
What are continental divides?
97% of the water on earth is of this type
What is salt water
Road salt is an example of this
What is a chemical contaminant?
In this step, Wastewater is disinfected with chlorine to kill harmful organisms.
What is step 4 in the wastewater treatment process?
You can test this by lowering a black and white disk into a water source.
What is turbidity?
These are the areas between the divides.
What are watersheds?
Grams/Litre
What unit of measurement is used for salinity
Wastes from animals, and parasites are examples of this.
What is a biological contaminant?
In this step, Wastewater is screened and moved into the grit tank. It then moves to the settling tank for a few hours.
What is step 1 in the wastewater treatment process?
You can test this by using a pH test paper.
What is acidity?
There are 36 of these in Ontario. They are organizations that manage and protect watersheds.
What is a Conservation Authority?
Salt is removed from salty water leaving fresh, drinkable water.
What is desalination?
This occurs when warm water is dumped into a river by factories.
What is thermal pollution?
In this step, Wastewater then moves to the clarifier where any remaining solids settle to the bottom.
What is step 3 in the wastewater treatment process?
This describes water that is very cloudy.
What is turbidity?
All of this from within a watershed leaves the watershed at the same exit.
What is runoff?
Only 3% of Earth's water is this type and most of it is frozen in glaciers and polar ice.
What is fresh water?
Salt, sediment, animal waste, fertilizers, and pesticides/herbicides can all enter a water source by this method.
What is runoff?
In this step, Solids from the settling tank and the clarifier are processed.
What is step 5 in the wastewater treatment process?
Conductivity apparatus can indicate the presence of this in water.
What is salt?
This is an area surrounded by high land and drained by a river and its tributaries.
What is a watershed?
