One of the worst ways to add weight to a paper mill is by adding fixes to patch processes that, if run properly would not need a fix.

So called "jockey pumps" often fit in this category.  Every mill has them, even if they don't call them this.  They are pumps put in series with an original pump because either (a) the original pump was undersized or (b) the original pump is half worn out.

The proper thing to do is to size equipment properly, or if sized improperly, replace it with equipment that is sized properly.  Of course, this takes real engineering effort, something that is often in short supply these days.

Sadly, this bad practice is widespread.  I have not walked through a mill over six months old that is not doing this.

What examples of adding equipment that is a band aid can you tell us about?  What have you seen done to reduce or eliminate this problem?
