Food processing is a good example of how the focused production of specific goods creates higher loads of specific waste contaminants. Simple (yet annoying) effects of high wastewater contaminants can be bad odors and clogged drains. 

Heat exchangers, boilers and other water-contacted vessels are integral parts of many industrial plants. Often, when people think of protecting these components from corrosion, their minds fast-forward to corrosion issues that occur after the equipment is installed.

Industrial process cooling equipment such as cooling towers or chillers can corrode before they are installed or while they are temporarily laid up for the season. This is especially so if equipment is exposed to harsh outdoor conditions during shipping or storage.

Winter layup is a perilous time for cooling systems: Cooling towers and pipes that are shut down risk severe corrosion.
