Wastewater Treatment

Moorestown Wastewater Treatment Plant

Physical (primary) Processing

• Bar Screens in grit chamber: traps large debris

• Material is dried & sent to landfill

• Primary Clarifier: settling tank. Material skimmed off top. Heavier solids settle and drawn off the bottom. Waste sent to digester

Biological (secondary) Processing

• Anaerobic Digester: closed tank with floating lid. Microbes in break down organic matter (microorganisms, plant matter, etc).

• Methane produced. Can be used in cogeneration.

• Leftovers are landfilled after being dewatered.

• Wastewater is sent to aeration tank. Aerobic digestion occurs.

• Amount of nutrients decrease, BOD decreases.

Final Treatment

• Wastewater is sent to settling tanks

• Pumped through UV or chlorine-based system to sterilize/kill bacteria.

• Treated water is sent into a waterway.
