Embodiment

[0051] use figure 1 The enrichment device carried out the concentration test of microorganisms.

[0052] As microorganisms, coliform bacteria with an average particle diameter of 2 μm and chlorella with an average particle diameter of 7 μm were used. Magnetite particles with an average particle size of 0.2 μm, 1 μm, and 2 μm, and Mn-Mg-Sr ferrite particles with an average particle size of 4 μm, 8 μm, and 30 μm are used as particulate filter aids, and are stored as an aqueous slurry with a predetermined concentration. In the filter aid storage tank 14. On the other hand, an aqueous suspension of microorganisms adjusted to a concentration of 1000 mg / L (moisture conversion) was prepared in the culture tank 15 , and a filter cloth with a mesh of about 3 μm was used as the filter material 222 .

[0053]Next, the above-mentioned microbial suspension is supplied to the mixing tank 111, and the particulate filter aid is supplied from the filter aid storage tank 14 to the mixing tank...

Abstract

A microorganism concentrating apparatus includes a mixing device, a filtering device, and a magnetic separation device. The mixing device is configured to mix an aqueous suspension of microorganisms with a particulate filter aid including magnetic particles to prepare an aqueous slurry of the microorganisms and the particulate filter aid. The filtering device is configured to filter the aqueous slurry supplied from the mixing device to provide a filter cake includes the microorganisms and the particulate filter aid, and to provide a filtrate. The magnetic separation device is configured to magnetically separate the filter cake supplied from the filtering device into the microorganisms and the particulate filter aid.

Description

[0001] This application is based on Japanese Patent Application No. 2011-55803 (filing date: March 14, 2011), claims the priority of this Japanese Patent Application, and includes the entire content of this application by referring to this Japanese Patent Application. technical field [0002] Embodiments of the present invention relate to a microorganism concentrating device and a concentrating method. Background technique [0003] Among water microorganisms represented by algae, there are many microorganisms capable of synthesizing useful substances, and these microorganisms can be cultivated to produce useful substances. Examples of microorganisms that can produce useful substances include Chlorella, which is used for health foods, and oleaginous bacteria, which can be used as non-fossil fuels. [0004] In order to effectively utilize these microorganisms, concentration after cultivation is required. And, in addition to these microorganisms that can produce useful substan...
