Aerobic Treatment Process - Ghangrekar

When the wastewater is sprayed in the air more surfacearea of wastewater is brought in contact with the air and hence aeration will occur at accelerated rate . Detention period of the aeration tank treating sewage is usually 5 to 8 hours. The volume of aeration tank should be worked out considering the return sludge volume. Figure 19.3

Physiology — Institute For Altitude Medicine

At 14,000 ft, the air has 43% less oxygen than at sea level. Because of the reduced air pressure at high altitude, the volume of air you breathe into you lungs contains less oxygen molecules in each breath. Physiological changes. Your body must adjust to the lower oxygen levels, and this process of adjustment is called acclimatization.

Oxy-Combustion | netl.doe.gov

In this process, almost all the nitrogen is removed from the air, yielding a stream that is approximately 95 percent oxygen. Hence, the volume of flue gas, which is approximately 70 percent CO 2 by volume, from oxy-combustion is approximately 75 percent less than from air-fired combustion. The lower gas volume also allows easier removal of the ...
