Water softening is the removal of calcium, magnesium, and certain other metal cations in hard water. The resulting soft water requires less soap for the same cleaning effort, as soap is not wasted bonding with calcium ions. Soft water also extends the lifetime of plumbing by reducing or eliminating scale build-up in pipes
The reduction of blowdown by dealkalization keeps the water treatment chemicals in the boiler longer, thus minimizing the amount of chemicals required for efficient, noncorrosive operation. [2] Carbonate and bicarbonate alkalinities are decomposed by heat in boiler water releasing carbon dioxide into the steam.
This is desirable because products, such as citric acid, are added to food oils the tank will begin to settle over time with the heavier contents sinking to the bottom. However, a system that utilizes nitrogen sparging (and then subsequently tank blanketing once the nitrogen reaches the vapor space) may have negative impact on the products ...
More recently, however, the FDA expanded the recall on Sept. 30 to include an additional brand of eggs and raised the risk level. ChrisAt/istockphoto What's the Latest Update?
Removable insulation blankets for hot components: used to prevent heat from escaping components by covering the surface of component with insulation materials that slow the transfer of heat. Removable insulation blankets for cold components: used to prevent external heat from affecting a chilled pipe.
Cage-Free. As the label implies, the hens that produce cage-free eggs, do indeed live outside of cages.However, that does not mean that they have room to roam around. "They are often kept indoors ...
Ion exchange is a method widely used in household filters to produce soft water for the benefit of laundry detergents, soaps, and water heaters. This is accomplished by exchanging divalent cations (such as calcium Ca 2+ and magnesium Mg 2+) with highly soluble monovalent cations (e.g., Na + or H +) (see water softening).
Fill a bowl or clean sink basin with cool water. Place potatoes in the water, and let them soak for 15 minutes to allow dirt and grime to loosen. Using a vegetable brush, thoroughly scrub the ...
