Abstract
An apparatus for preparing and dispensing a flocculant solution to dewatering an aqueous process stream includes a mixing pump, a maturing tank, and a feeding unit. The mixing pump mixes the flocculant solution and builds up a pressure onto the flocculant solution. The maturing pressure tank is fluidly connected with the mixing pump, so that the pressurized diluted flocculant solution is led from the mixing pump into the maturing pressure tank and matured therein under pressure that is above atmosphere pressure.
