Abstract:
1. A process for optimizing the removal of total organic carbon (TOC) from water while enhancing the performance of a membrane filter in a filtration system, comprising: dispersing an effective amount of coagulant into a volume of water in a first tank; rapidly agitating said water in a first zone of said first tank, then agitating said water more slowly in a second zone of said first tank; adjusting a pH level of said water in said first tank to a first pH set point selected for optimum TOC removal; directing said water at said first pH set point through a liquid-solid separator device to remove chemically-precipitated particulates and into a second tank; rapidly agitating said water in a first zone of said second tank, then agitating said water more slowly in a second zone of said second tank; adjusting a pH level of said water in said second tank to a second pH set point selected for optimum performance of said membrane filter; and directing said water at said second pH set point through said membrane filter.
