Why is there anaerobic respiration even in organisms that live in aerobic condition like human beings? View Solution Activated sludge should have the ability to settle quickly so that it can (a) be rapidly pumped back from sedimentation tank to aeration tank (b) absorb pathogenic bacteria present...
Water Treatment Solutions Why oxygen dissolved in water is important Why Dissolved Oxygen is Important Dissolved oxygen The dissolved oxygen (DO) isoxygenthat is dissolved in water. The oxygen dissolves by diffusion from the surrounding air; aeration of water that has tumbled over falls and rapids;...
The problem isn’t just a lack of toilets—it’s a lack of toilets that people want to use. The result: millions of deaths and disease-stunted lives.
It is harder to pinpoint the problems, especially if the issue does not lie in improper water parameters such as pH, ammonia, or temperature. Therefore, it is important to focus more on preventive measures so as to ensure your fish never have to suffer after water changes. You do this by...
Low levels of salt in the water aid in the osmotic balance of the fish by making the water salinity closer to the fish's blood salinity. That helps the fish
(many of them agricultural pests). Ants are essential ecosystem engineers: many species build nests and dig tunnels in the ground, increasing aeration and drainage, and improving soil fertility with their waste and food stores. Some seed-eaters are important for plant reproduction: they stock ...
To prevent or restore unbalanced ecosystems, it’s critical to control problems as they occur. When it comes to lakes or larger ponds, current treatment methods include aeration, mixing, and ultrasound. As an alternative for harsh chemicals, we’ve developed an ultrasonic, floating unit that effe...

In ARDS patients, the change from supine to prone position generates a more even distribution of the gas–tissue ratios along the dependent–nondependent axis and a more homogeneous distribution of lung stress and strain. The change to prone position is generally accompanied by a marked improvement...
Aeration is done by a silicone rubber membrane inside the vessel. The system was tested using hamster kidney fibroblasts, and cell densities of 107 cells/ml were reached (Schwarz et al. 1992). Furthermore, bioreactors were also developed for the purpose of nutrient recycling, meaning the ...
