Sentences with phrase «osmosis pressure»

Not exact matches

Forward osmosis relies on a similar system, and it doesn't require the high - pressure pumps that reverse osmosis uses.

Reverse osmosis involves passing sea water through a thin - film membrane at a pressure of 1,000 to 1,500 per square inch.

Forward osmosis uses membranes to concentrate liquids but it uses considerably less pressure than evaporation, therefore it uses less energy, there is significantly less fouling and cleaning is easier.

Other concentration technologies include membrane systems such as reverse osmosis, which also use pressure.

a. Reverse Osmosis — Use of high - pressure pump and special membranes, called semi-permeable membranes, to reverse the natural phenomenon of oOsmosis — Use of high - pressure pump and special membranes, called semi-permeable membranes, to reverse the natural phenomenon of osmosisosmosis.

But even with respect to the older child, I believe that Satter would say (and she indicated as much in an email to me) that with respect to any behavior at the table, whether it's eating vegetables or putting one's napkin on one's lap, children learn far better by osmosis — by observing your behavior — than through any overt parental pressure, which more often than not can backfire.

Wind power provides the pressure necessary to suck the well's saltwater through a series of filters and membranes laced with copper and silver ions to kill off any potential pathogens, rather than the more expensive chemical compounds used in reverse - osmosis plants.

At the same time, if too much saltcollects in the soil around the plant, a pressure differential arises, and water is sucked from the roots by osmosis.

Root pressure is created by water moving from its reservoir in the soil into the root tissue by osmosis (diffusion along a concentration gradient).

The most common desalination technology, known as reverse osmosis, involves applying pressure to seawater to force salt ions through a membrane.

For instance, they use reverse osmosis, in which water is forced at enormous pressure through membranes that screen out salt.

By running the irrigation lines with built - in reverse osmosis membranes underground, the proposed irrigation system would use the pressure gradient supplied by the plants» roots to desalinize the water without the high amount of energy consumption usually associated with desalination.

MIT says, «When bent even a slight amount, the layered composite produces a pressure difference that squeezes lithium ions through the polymer (like the reverse osmosis process used in water desalination).

That process requires much tighter membranes (like reverse osmosis membranes), and a huge amount of water pressure or energy.

Note: cooling water from ships» diesel engines was used to heat sea water for low pressure evaporation to produce ships» drinking water before reverse osmosis distillers became practical.

The high - pressure water can also be used to supply a reverse osmosis desalination plant, replacing electrically driven pumps usually required for such plants.
