Problems solved by technology

However, in these methods, when the above-mentioned liquid with high turbidity is filtered, the effect of obtaining sufficient clarity and filtration speed of the filtrate is limited, and the performance equivalent to diatomaceous earth cannot be obtained.

Embodiment

[0081] Hereinafter, based on an Example, this invention is demonstrated more concretely. Of course, the present invention is not limited to the following examples.

[0082] Each measurement value in the following Examples, Comparative Examples, and Reference Examples was measured at three points, and the average value thereof.

reference example 1

[0083] Reference Example 1 Biomass used as a sample

[0084] Using a continuous shredder (manufactured by IKA, MF10 basicS1), rice straw and wheat straw as biomass were pulverized to a size of 2 mm to 3 mm to obtain pulverized biomass.

reference example 2

[0085] The measuring method of reference example 2 moisture content

[0086] Regarding the moisture content, the sample was kept at a temperature of 120° C. using an infrared moisture meter (manufactured by Ketto Scientific Research Institute, FD-720), and a value obtained from the difference between the stable value after evaporation and the initial value was measured.

Abstract

Disclosed is a cellulose-based filter aid with high turbidity removal capability, and a manufacturing method thereof. This method of manufacturing a filter aid involves (A) grinding and / or thermochemically treating a cellulose-containing biomass to obtain a pre-treated biomass, (B) a step for treating with cellulase the pre-treated biomass obtained in step (A) to obtain a cellulase-treated product, and a step (C) for obtaining the solid component of the cellulase-treated product of step (B). This cellulose-based filter aid contains the water-insoluble cellulase-treated product of a cellulose-containing biomass.

Description

technical field [0001] The present invention relates to a method for producing a cellulose-based filter aid. Background technique [0002] The process of obtaining a clear liquid from a highly turbid liquid is one of the important processes in the food industry and wastewater treatment. A centrifugation method is known as a method for removing turbid substances contained in such a highly turbid liquid. [0003] As a centrifugal separator used in this centrifugation method, a spiral decanter type centrifugal separator is known. However, although this centrifuge is famous for its processing speed and scale-up, it only generates a centrifugal force of about 2000 to 3000G, and it is difficult to efficiently remove turbid components. In addition, as a high-speed continuous centrifuge with a centrifugal force of about 8000G, there is a Delaval type centrifuge, but in the case of this centrifuge, it cannot be processed when the solid content concentration is high, and in addition...
