Sidestream softening of cooling water eliminates blowdown discharges to the environment. The lime-soda softening process removes calcium, magnesium, and silica, which are the primary causes of scale formation on heat exchange surfaces. The treated water can then be recycled to the cooling water system. The only discharges are drift, or fine droplets entrained in the air circulating through the cooling tower, and sludge from the softener. Cooling water and softening chemistries are described.
