Chloride cycle dealkalizers operate similar to sodium cycle cation water softeners. Like water softeners, dealkalizers contain ion-exchange resins that are regenerated with a concentrated salt solution - NaCl. In the case of a water softener, the cation exchange resin is exchanging sodium (the Na + ion of NaCl) for hardness minerals such as ...
Brine draw: Water is directed through a jet pump, which pulls salt water from the brine tank, before the water and brine pass through the resin bed in the normal direction, if co-current, or in the reverse direction, if counter-current. [12] The output of this typically thirty-minute process is discarded through the drain hose.

The donkey's mama was so impressed by him. The little guy was on his way to learning how to roll over! He just wanted to practice his new moves real quick before it was time to go to sleep.
Although sedimentation might occur in tanks of other shapes, removal of accumulated solids is easiest with conveyor belts in rectangular tanks or with scrapers rotating around the central axis of circular tanks. [8] Settling basins and clarifiers should be designed based on the settling velocity (v s) of the smallest particle to be ...
An elderly straphanger was randomly shoved onto subway tracks at the Herald Square station in Manhattan on Sunday afternoon, according to police.
Some have vertical walls, others look like saucers or shallow basins, and some generate ponds by retaining water, according to the U.S. Geological Survey. The depressions are common in Florida ...
