How is polyacrylamide applied and what forms does it come in for application

 polyacrylamide 's three most common forms are dry granules, solid blocks (cubes), and emulsified liquids.The application method of polyacrylamide  chosen depends on the form of   polyacrylamideselected. The use of dry granular  polyacrylamide into irrigation water is facilitated by the use of an augured metering system and excellent mixing and thorough dissolving before the   polyacrylamidereaches the irrigated furrows.   polyacrylamideblocks ( or cubes) are usually placed in wire baskets that need to be secured to the edge of the ditch to avoid washing of the blocks down the ditch. Liquid   polyacrylamidecan be metered directly from the container into the irrigation ditch, directly into the furrow, or through a pipe line or injector pump.Read morehttp://www.chemical-chem.com/Papermaking-chemicals/Polyscrylamide/
