The present disclosure pertains to filtration methods comprising: passing a first fluid that comprises cells, cell debris and targeted product produced by the cells through a first filter thereby separating the first fluid into a first retentate comprising cells and a first permeate comprising targeted product and cell debris; combining resin beads having affinity for targeted product with the first permeate to form a second fluid containing resin beads with bound target product and cell debris; passing the second fluid through a second filter thereby separating the second fluid into a second retentate comprising resin beads with bound target product and a second permeate comprising cell debris; combining an elution buffer with the second retentate to form a third fluid that comprises a mixture of resin beads and unbound targeted product; and passing the third fluid through a third filter thereby separating resin beads from targeted product.

A system for generating electricity, heat, and desalinated water having a gas turbine system connected to a first electric generator, a waste heat recovery boiler (WHRB) system, a combined heat and power (CHP) generation system connected to a second electric generator, one or more solar powered energy systems, and a desalination system. The desalination system is connected to the CHP generation system and the WHRB system. The gas turbine system generates electricity and heat, the WHRB system is connected to and uses the exhaust of the gas turbine system to provide heat and steam power to the CHP generation system. The CHP generation system produces and provides electricity and heat to the desalination system, which produces product water, and at least one solar powered energy system provides thermal energy to one or more of the gas turbine system, the WHRB system, the CHP generation system, and the desalination system.

The present invention provides for a method for separating starch from processing solutions containing starch containing plants or roots such as potatoes, sweet potatoes, wheat, corn, tapioca, yams, cassaya, sago, rice, pea, broad bean, horse bean, sorghum, konjac, rye, buckwheat and barley to provide commercially acceptable starch while reducing disposal of solid or liquid waste matter into landfills or water treatment facilities.

A filtration treatment system of raw water includes a raw water supply line to supply raw water, a filtration device provided on the raw water supply line to filter impurities in the raw water, a separation device provided on a rear side of the filtration device and equipped with a separation membrane to separate filtered raw water into permeated water and concentrated water; an organic substance monitoring device provided on either front or rear or both front and rear of the filtration device to monitor an amount of an organic substance in the raw water, and a control device to execute backwashing of the filtration device with the permeated water as backwashing water in a case in which the amount of the organic substance in the raw water exceeds a reference value as a result of monitoring by the organic substance monitoring device.

The present teaching relates to method, system, medium, and implementations for storage management. A hash table is constructed, having an index file having one or more slots, each of which includes one or more buckets. Each bucket stores one or more types of records, including a direct record, an indirect record, and a forwarding record. A direct record stores data directly in a bucket of a slot of the index file. When a storage request is received related to some relevant data, the request is handled based on the constructed hash table.

The present invention relates to a water treatment method including: a filtration step of feeding water to be treated to a membrane filtration device having loaded therein a porous separation membrane and performing filtration treatment to obtain filtrate; a discharging step of discharging the water to be treated in the membrane filtration device, which has been separated and concentrated by the porous separation membrane; and a cleaning step of cleaning the porous separation membrane by at least one treatment of physical cleaning and chemical cleaning, in which a cycle including a combination of the filtration step, the discharging step and the cleaning step is repeated multiple times, thereby obtaining filtrate. In each cycle, the filtration step and the discharging step are repeated multiple times, and the cleaning step is then carried out.

A method of producing a sugar liquid includes: (A) reacting mannanase with a liquid component obtained by hydrolysis treatment of woody biomass to obtain a saccharified liquid; and (B) filtering the saccharified liquid in Step (A) through a microfiltration membrane and/or ultrafiltration membrane to collect a sugar liquid from a permeate side.

The present invention relates to methods and systems for optimization of dilution of a viscous starting material to isolate and/or concentrate the product of interest from the starting source material such that the process minimizes the volume of diluent and the total volume of the waste stream generated during the process as well as maximizing the yield of desired product. The system employs cross-flow filtration modules with sub-channels that are equidistant to the inlet and outlet of said modules and such modules are characterized by optimal channel height, optimal transmembrane pressure, etc., which are selected in order to achieve the best combination of product quality and production yield.

A methane fermentation system which can efficiently generate methane gas is provided. The methane fermentation system decomposes an organic waste with an anaerobic microorganism to cause methane fermentation so as to generate the methane gas. The methane fermentation system includes a wet bead mill which finely pulverizes the organic waste. The methane fermentation system also includes a methane fermentation chamber in which the organic waste finely pulverized in the wet bead mill is decomposed with the anaerobic microorganism to cause the methane fermentation so as to generate the methane gas.
