Process for control of micro-organisms in process streams

Claim 1

A PROCESS FOR CONTROLLING THE GROWTH OF MICRO-ORGANISMS COMPRISING THE STEPS OF (A) CONTINUOUSLY SUPPLYING A SOLUTION OF SULFAMIC ACID, (B) CONTINUOUSLY MIXING AND REACTING SAID SULFAMIC ACID SOLUTION WITH A HYPOCHLORITE SOLUTION IN A REACTOR VESSEL TO FORM A REACTION PRODUCT SOLUTION OF NCHLOROSULFAMIC ACID, (C) DELIVERING SAID N-CHLOROSULFAMIC ACID SOLUTION TO AN INTERMEDIATE STORAGE VESSEL, (D) CONTINUOUSLY SUPPLYING SAID N-CHLOROSULFAMIC ACID SOLUTION FROM SAID INTERMEDIATE STORAGE VESSEL TO AQUEOUS PROCESS STREAMS REQUIRING CONTROL OF THE GROWTH OF MICRO-ORGANISMS, (E) REGULATING THE RATE OF SUPPLY OF SULFAMIC ACID SOLUTION BY LIQUID LEVEL IN SAID INTERMEDIATE STORAGE VESSEL, (F) REGULATING THE RATE OF SUPPLY OF SAID HYPOCHLORITE SOLUTION BY THE OXIDATION POTENTIAL OF THE N-CHLOROSULFAMIC ACID SOLUTION LEAVING SAID REACTION VESSEL, AND (G) REGULATING THE RATE OF SUPPLY OF SAID N-CHLOROSULFAMIC ACID SOLUTION TO SAID AQUEOUS PROCESS STREAM TO MAINTAIN A RESIDUAL ACTIVE CHLORINE CONTENT OF FROM 0.1 TO 5 PARTS PER MILLION, MEASURED DOWNSTREAM FROM THE POINT OF INTRODUCTION OF SAID NCHLOROSULFAMIC ACID.
