Preventing equipment corrosion of water treatment equipment

dehumidification plays a crucial role in the management and maintenance of waste and freshwater treatment facilities. Metal surfaces such as maintenance, treatment, and filtration tanks, pipelines, and pump room equipment are exposed to cold water, which usually causes their surface temperature to be lower than the indoor dew point temperature. When this happens, these surfaces will generate moisture, leading to rust and corrosion

In freshwater treatment plants located above ground level, water from the ground may be as cool as 50 degrees Fahrenheit. In colder months, the water quality obtained from lakes or rivers may be as low as 33 degrees Fahrenheit. Underground freshwater treatment facilities may face greater water control challenges than surface installations However, the appropriate application of industrial dehumidification systems can maintain the indoor dew point temperature at a temperature three to five degrees lower than the coldest surface temperature. This helps to control the formation of moisture on the metal surface and prevent premature corrosion of the equipment

Wastewater treatment facilities encounter similar challenges as freshwater plants, but consider the combustibility of air in the treatment environment. Therefore, in some wastewater treatment plant applications, industrial dehumidifier must be designed and manufactured in accordance with Class 1 and Class 2 standards of the national electrical code for "explosion-proof" equipment enclosures

Each fresh and wastewater treatment plant is unique and may require customized solutions
