Abstract: Method for separating a precipitate from a liquid, including:—inducing transport of at least part of the precipitate to an upper surface of the liquid; and—removing precipitate from the upper surface of the liquid. The invention further provides a system for separating a precipitate from a liquid, wherein the system includes:—a container (1) for receiving a liquid wherein precipitate is and/or has been formed;—a precipitate transport inducing means (3) for inducing precipitate transport towards an upper surface of liquid, held in the container (1) during operation; and—a precipitate removing means (5) for removing precipitate from a precipitate removal level within the container (1), the precipitate removal level being associated with an upper surface of liquid, held in the container (1) during operation. The invention also provides a process for the recovery of water soluble biopolymers from an aqueous solution.
