Cooling tower - Wikipedia

A cooling tower is a heat rejection device that rejects waste heat to the atmosphere through the cooling of a water stream to a lower temperature. Cooling towers may either use the evaporation of water to remove process heat and cool the working fluid to near the wet-bulb air temperature or, in the case of closed circuit dry cooling towers, rely solely on air to cool the working fluid to near

The SHMP dosage is based on a 5–10 ppm level in the RO feed water. Coagulant dosage upstream of the sand filters is 1–2 ppm, if required. The silt density index (SDI), an indicator of colloidal fouling, was consistently in the range of 0.5–1.0, indicating the feed seawater is very clean. This is because the seawater feed intake is a well.

Water treatment - Wikipedia

Internal treatment within the boiler is focused on limiting the tendency of water to dissolve the boiler, and maintaining impurities in forms least likely to cause trouble before they can be removed from the boiler in boiler blowdown. Cooling water treatment. Water cooling is a method of heat removal from components and industrial equipment.

Antifreeze - Wikipedia

Most automotive engines are "water"-cooled to remove waste heat, although the "water" is actually antifreeze/water mixture and not plain water.The term engine coolant is widely used in the automotive industry, which covers its primary function of convective heat transfer for internal combustion engines.When used in an automotive context, corrosion inhibitors are added to help protect vehicles

If the heat is used for power generation, it can save up to half of the electricity used in the clinker process. Heat-recovery opportunities, however, are closely tied to the basic structure of the kiln: an advantage of the preheater, precalciner kilns is that waste heat is used in the first two stages.

Manual on hatchery production of seabass and gilthead

Seabass and gilthead seabream are the two marine fish species which have characterized the development of marine aquaculture in the Mediterranean basin in the last three decades. The substantial increase in production levels of these two species, initially of very high value, has been possible thanks to the progressive improvement in the technologies involved in the production of fry in
