Abstract
A fluidized flocculant being a dispersion of from about 5 to 60 weight percent of finely ground polyacrylamides in a fluid, water soluble polyhydric alcohol carrier. The fluidized flocculant is prepared as a dispersion having a particle size of less than 75 microns and can be metered and pumped into a water stream and mixed therewith to form a flocculant solution that can be readily metered and pumped into water to be clarified.
Claims11
A fluidized flocculant for use in an aqueous system comprising a dispersion of a finely ground polyacrylamide flocculating agent in a polyhydric alcohol carrier having an approximate molecular weight greater than 65 and less than 500 said dispersion being flowable at room temperature, the concentration of said flocculating agent in the dispersion being substantially greater than the concentration dissolvable in the aqueous system.
A method of producing a fluidized flocculant, comprising steps of:
- mixing from about 5 to 60 weight percent, based upon the total composition, of polyacrylamides together with a polyhydric alcohol carrier having an approximate molecular weight greater than 65 and less than 500 to form a slurry, and milling said slurry to a particle size of approximately 75 microns to form a dispersion.
A method of producing a fluidized flocculant comprising the steps of:
- grinding polyacrylamides to a particle size of approximately 75 microns, and mixing from about 5 to 60 weight percent of the ground polyacrylamides with a polyhydric alcohol carrier having an approximate molecular weight greater than 65 and less than 500 to form a flowable dispersion.
