CORROSION CASE HISTORIES: PROBLEMS AND SOLUTIONS OF AGGRESSIVE WATERS IN COOLERS AND CONDENSERS Available to Purchase

It has often been said that water can be, effectively, one of the most corrosive substances known, and many papers have been written on this theme, but perhaps the experiences related here may be sufficiently unusual to prove interesting and informative to those with similar problems. The hard, brackish water pumped from wells in the area adjoining the Manchester Ship Canal south‐west of Warrington caused some unexpected and troublesome plant breakdowns, particularly in 1958 and 1959. Another supply of water on the site, piped from Lake Vyrnwy in Wales, was soft and a source of slime‐producing organisms. Several years elapsed before these waters were understood and most of the difficulties resolved.
