Wastewater Treatment Methods Quiz

• Primary treatment removes suspended impurities from wastewater by passing it through a mixed or a moving bar screen followed by the comminutor and then the resulting water enters the grid chamber where the grids are disposed.
• Screening removes suspended impurities by passing the wastewater through a mixed or a moving bar screen followed by the comminutor and then the resulting water enters the grid chamber where the grids are disposed.
• Sedimentation allows the water to stand undisturbed in high tanks at about 5m deep under the force of gravity.
• Flotation clarifies wastewaters by the removal of suspended matter such as oil or solids.
• Secondary treatment processes include: Aerobic biological treatment and Anaerobic biological treatment.

Test your knowledge of primary and secondary methods used in the treatment of wastewater, including screening, sedimentation, and flotation processes.
