Claim Text:
1. Method for removal of organic and/or inorganic pollutants from a continuous liquid stream comprising the steps of: selecting a continuous liquid stream to be treated based upon a selection criteria, said selection criteria comprising ascertaining that the chemical composition of the continuous liquid stream prevents cations otherwise capable of linking/crosslinking hydrocolloids from so linking/crosslinking at an initial pH value, measuring the pH of the continuous liquid stream to be treated to determine the initial pH value; determining an amount of a pH-increasing reactant to add to the continuous liquid stream to effectuate a pH peak of above 10 in at least a portion of the continuous liquid stream, and within 15 seconds thereafter, a decrease to below pH 10 and a continued decrease in pH towards the initial pH value; adding the pH-increasing reactant in the determined amount at a location in the continuous liquid stream to effectuate a pH peak above 10 and a pH decrease thereafter within 15 seconds, adding a hydrocolloid to the continuous liquid stream just prior to, during, or within 15 seconds of effectuating the pH peak, whereby the hydrocolloid attaches with the organic and/or inorganic pollutants in the continuous liquid stream and links/cross links to form a flocculate, and removal of the flocculate.
