Wastewater Treatment Process Concepts

The Spanish Fork Wastewater Treatment Plant, operational since 1956, is undergoing upgrades to meet growing demands. The video explains the treatment process, starting with step screens and grit chambers to remove solids, followed by primary and secondary clarifiers for sludge removal. Aeration basins and trickling filters further treat the water, which is then disinfected in a chlorine contact basin. Sludge is processed in digesters and a belt press, with the final product used as fertilizer or sent to landfills. The new plant will enhance efficiency and compliance with standards.

What year did the Spanish Fork Wastewater Treatment Plant begin operations?

• 1990

• 1965

• 1980

• 1956

What is the purpose of the step screens in the wastewater treatment process?

• To heat the water

• To remove large solids from the wastewater

• To add chemicals to the water

• To increase the water flow speed

What happens to the solids collected in the grit chamber?

• They are burned

• They are taken to the landfill

• They are used as fertilizer

• They are recycled

How do primary clarifiers help in the treatment process?

• By using gravity to settle dense materials

• By filtering out bacteria

• By heating the water

• By adding chlorine to the water

What is the function of the screw pump in the intermediate pump station?

• To filter out solids

• To add air to the water

• To remove bacteria

• To pump water to a higher tank

What is the role of good bacteria in the aeration basins?

• To treat wastewater by breaking down organic matter

• To increase water temperature

• To remove chlorine

• To add nutrients to the water

Why is the trickling filter no longer sufficient for current standards?

• It is too expensive

• It does not provide the required cleanliness

• It uses too much energy

• It is too slow

What is the purpose of the chlorine contact basin?

• To remove solids

• To increase water flow

• To disinfect the water

• To add nutrients

How long does it take for sludge to pass through all four digesters?

• 15 days

• 20 days

• 10 days

• 5 days

What happens to the dried sludge after it is processed?

• It is stored indefinitely

• It is released into the river

• It is burned for energy

• It is used as fertilizer or taken to the landfill
