Cooling Towers and Salt Water
For cooling tower service, any circulating water with more than 750 parts per million chloride expressed as NaCl is generally considered as salt water. However, the effects of chlorides will be much less severe at 750 ppm than they will at higher concentrations.
Cooling Tower Energy and Its Management
Because of the fuel shortages which began to manifest themselves in the early 1970s, the cost of energy began an asymptotic rise. The level of attention to energy savings has risen as a part of a broader green approach to design, including carbon footprint.
Purposes and Types of Fill
The relationship between water surface exposure and heat transfer rate is intrinsic to all types of cooling towers, regardless of the type of water distribution system utilized. The more water surface exposed to given flow of air, the greater will be the rate of heat transfer.
White Rust and Water Treatment
The best cure for white rust is an ounce of prevention when you begin operating your tower. Consult with your water treatment specialist and ask about his program for initial system operation and passivation of your galvanized steel cooling tower. We encourage early operation with near neutral pH water and use of only reasonable levels of film-forming inhibitors.
