WIDE-RANGING WATER optimization efforts, from fixing pipe leaks to minimizing cooling tower blowdown, are providing significant savings to chemical makers.On March 29th, for example, BASF Research, Ludwigshafen, Germany, highlighted its latest water treatment developments at a conference there.One of these is a pilot scheme to improve use of Rhine river water at the site. The company currently is benchmarking an existing ultrafiltration system (UF) against one that uses a novel - and unnamed - membrane fiber. In trials, the new membrane has generated lower pressure buildup, requiring 50% fewer cleanings. In addition, it provides higher flux, 114 L/m~2/h, compared to 86 L/m~2/h in the other unit, giving 33% additional clean water per module (Figure 1).
