The effects of polymer flocculation before manure separation were investigated, through testing both a linear and a branched polymer. Centrifugation removed 60% of phosphorus from raw manure (control), whereas raw manure clogged the filters during gravity drainage and pressure filtration.
When polymer sheering does occur, the flocculated particles are much more likely to bind together again. Especially effective in waters with high salinity and high chloride levels, where dissolved air or gas floatation is used as the sludge separation method.

Flocculation and separation of the extracts using the polymer appear to occur over longer periods of time, of the order of a few hours. A possible way to accelerate the separation is to attach heavier particles to cause faster settling. Kaolin clay is anionic, inert and is widely available as filler and coating mineral in papermaking.
Polymer induced flocculation and separation of particulates from extracts of lignocellulosic materials
Flocculation water treatment is the process of bring together the destabilized, or “coagulated,” particles to form a larger agglomeration, or “floc.” Flocculation, the agglomerations of destabilized particles into large particles, can be enhanced by the additional of high-molecular-weight, water-soluble organic polymers.
