A method and a process arrangement for improving a solid-liquid separation of solids from a hydrolyzed material formed in an enzymatic hydrolysis of lignocellulosic material, comprising following step: i) adding a flocculant additive to the hydrolyzed material or to a stream separated from the hydrolyzed material to form a mixture, and ii) separating a solid stream and a liquid stream from the mixture by means of a decantation or gravitational separation. Further is disclosed a solid product.

An apparatus and method are provided for removing ultra fine sediment suspended in water where the apparatus includes a sheet of open weave textile material, such as jute, that has a polymer flocculant applied thereto to provide a floe curtain for the water to flow through such that the suspended sediment can contact the flocculant and precipitate out of the water. The sheet comprises a top edge and a bottom edge with a top border disposed along the top edge of the sheet and a bottom border disposed near the bottom edge of the sheet. The top border comprises a first plurality of spaced-apart grommets disposed therealong. The sheet further comprises a geotextile tube disposed between the bottom edge and the bottom border. Two or more floe curtains can be placed in a spaced-apart configuration in the water to provide stages of successive filtering as the water flows through the floe curtains.

The present invention relates to a method for extracting microvesicles from a biological sample, the method comprising the steps of: adding a polyvalent cationic material to the biological sample to form an aggregate in which the microvesicles and the polyvalent cationic material are aggregated by electrical force; capturing the aggregate by a capture filter while the biological sample including the aggregate passes through the capture filter; and extracting the microvesicles by allowing an elution solution to pass through the capture filter with the aggregate captured therein to isolate the microvesicles from the aggregate. Accordingly, microvesicles may be extracted using a polyvalent cationic material, without a centrifugation process.
