Water Filtration Cycle

What is a Wastewater Trash?

• chemicals that are not safe to go to the processing plants.

• is a dirty water caused by rain, and spilled into the lakes or the bays.

• is collected from homes and sent to processing plants.

• Harmful water that wash off roads, parking lots, and rooftops can harm our rivers and lakes.

Sludge Digestion

• a biological process in which organic solids are decomposed into stable substances.

• a process to remove from the treatment plant

• a series of processes to get gasses from the treatment plant.

• a digestion method that stops the organic solids from increasing in size.

Overflow

• A overflow occurs when it's spilled into the lakes.

• An overflow happens when wastewater is spilled into the environment, and never went to wastewater treatment plant.

• An overflow happens when there is too much snow.

• A overflow is caused by too much water streamed from the lakes.

Why is the dryer process used in the wastewater treatment plant?

• it is used to boil water to make methane gas.

• used to dry up the pipes before the aeration process.

• to kill germs before the clean water is filtered.

• drying is the use of heat to evaporate water from wastewater residual solids.

Methane Gas in wastewater treatment

• Methane gas is healthy for people

• Methane Gas is used to burn scum and then treated for adding water.

• methane is a potent green- house gas that contributes to climate change

• Methane Gas comes from water.

What is aeration used for?

• Aeration is used for water filter before drinking.

• Aeration is air and chemicals to dissolve sludge.

• Aeration is an activated sludge process. It pumps air into a tank, promoting microbial growth in wastewater.

• Aeration is a type of gas that is caused by dirty water.

What is scum at the water treatment plant?

• floatable materials skimmed from the surface of primary and secondary settling tanks.

• Heavy materials arriving at the water treatment plants.

• overflow from sewer caused by heavy rain.

• materials at the bottom of the primary settling tanks.

Dry Sludge Finishing

• the last process of water filtration.

• is used to make methane gas for drying the wastewater materials.

• a final process before people can drink water.

• Takes more water out so that the solids of the sludge remains about 20 %, before it can be handled like a solid material.

what is Primary from the water treatment plant?

• Primary treatment of wastewater the first time before the rest of the plant.

• Primary treatment removes material that will either float or readily settle out by gravity.

• Primary refers to material that is burned.

• A process that removes water by gravity.

How is air used in the wastewater treatment plant?

• The air is used to fill up the tanks to keep the waste from overflowing.

• Using air to kill the microorganisms from the treatment.

• A method to promote microorganisms' growth that breakdown waste.

• The air is used to push the floating materials through the pipes in the wastewater plant.
