Abstract:
1. A process for optimizing the removal of total organic carbon (TOC) from water while enhancing the performance of a membrane filter, comprising: monitoring a TOC level of said water; dispersing an effective amount of a coagulant into said water based on the TOC level; monitoring a pH level of said water; and adjusting the pH level of said water, prior to said water being directed through said membrane filter, to align the particulate charge of said water with an electromagnetic surface charge of said membrane filter by measuring the particulate charge of said water using a micro amp streaming current monitor and dosing said water with acid or base to maintain the particulate charge of said water within an optimum charge window of between −9.8 and −9.4 micro amps for said membrane filter.
