Coagulation/Flocculation method

The present invention relates to a method of removing suspended solids from untreated water originating from a well, comprising the steps of: (1) measuring the total suspended solids (TSS) content and flow rate of the untreated water; (2) treating the untreated water with a calculated dosage of a cationic flocculant and/or cationic coagulant based on the TSS content and flow rate of the untreated water, to produce cationic flocculant and/or coagulant-treated water comprising a floc or agglomerated component; (3) separating the floc or agglomerated component of the cationic flocculant and/or coagulant-treated water from a clarified water component of the cationic flocculant and/or coagulant-treated water; (4) treating the separated floc or agglomerated component with a calculated dosage of an anionic flocculant, to produce anionic flocculant treated water comprising a floc component; and (5) separating the floc component of the anionic flocculant-treated water from a clarified water component of the anionic flocculant-treated water. The present invention also relates to a system for removing suspended solids from untreated water originating from a well. m 01 r~ - F 1 fiI zi < < 1-7 Owl Ij I CD Figure1I
