13-12: Water Reuse – As Time Goes by do the Less Attractive Approaches Cooling Tower Conversion The ISO 9001 quality system

The ISO 9001 quality system can be paraphrased as: (1) Make what the customer wants

using non-oxidizing biocides and dispersants

lowest cost to implement approaches were those most often implemented

13-12: Water Reuse – As Time Goes by do the Less Attractive Approaches Cooling Tower Conversion The ISO 9001 quality systemReuse of lower quality waters as make up water to Open Evaporative Cooling Water Systems has been implemented and practiced for several decades. The driving force was often image, lowering environmental impact, and or economic benefits (reduced operating costs). Paretos Principle was often followed if not strictly applied, the easiest, lowest cost to implement approaches were those most often implemented. With the passage of time, more stringent
