Title:
PARTICLE SUSPENSIONS OF FLOCCULATING POLYMER POWDERS
Document Type and Number:
WIPO Patent Application WO/2015/026481
Kind Code:
A3
Abstract:
Flowable liquid suspensions are described comprising blends of particulate water soluble high molecular weight polymer flocculants. The polymer flocculants can include polyethylene oxide, polyacrylamide, polyDadmac, Dadmac-acrylamide copolymers, copolymers thereof and combinations thereof The suspension allows the use of fine powders while reducing potential air quality and safety issues. The suspensions generally settle when mixing is stopped, but a uniform dispersion results when the suspensions are mixed, and the mixed suspensions can be delivered for use. The flocculant suspensions can be used for waste water purification, fiber dewatering, and the like.
