Embodiments of the present disclosure provide for systems for removing contaminants from a leachate, methods of removing contaminants from a leachate, and the like.

The present invention relates to separation methods and systems for converting high concentrations of animal wastes into useful products, wherein the separation of the desired useful products is conducted with a cross-flow filtration system having the ability to the separate desired useful energy and/or products from both viscous and non-viscous medium.

The invention relates to a method for filtering water comprising the use of a pump (14) to supply a filtering means (17), said supply being performed by simultaneous suction, for example by the same pump (14), through an ultrafiltration module (12).

An ultrapure water manufacturing facility includes: a first tank; a plurality of reverse osmosis membranes sequentially arranged downstream of the first tank; an electrodeionization device arranged downstream of the plurality of reverse osmosis membranes; an ion exchange resin tower arranged downstream of the electrodeionization device and filled with a boron selective resin; and a chemical supplier arranged between the plurality of reverse osmosis membranes and configured to supply a pH regulator to treatment-target water.

An automated waste water treatment system includes a collection tank constructed to hold waste water, a first flow line connected to the collection tank to output the waste water from the collection tank, an electrocoagulation unit that receives the waste water and outputs the waste water as coagulated waste water, a polymer dosage tank to provide a polymer dosage to the coagulated waste water to produce and output flocculated waste water. An air grid of the electrocoagulation unit, the latter housing a plurality of electrodes, increases the lifespan and efficiency of the electrodes to perform electrocoagulation of the waste water. A clarifier connected to the flow line receives the flocculated waste water and produces sludge-free waste water and concentrated sludge, a series of filters to output filter-treated water, and an ultrafiltration system that receives filter-treated water and outputs ultrafiltration-treated water to a reverse osmosis system.

A method for preparing a filtered beverage includes filtering a raw beverage using a cross-flow ultrafiltration device to produce a solids fraction and a liquid fraction; heating the solids fraction to a temperature of 60° C. or greater to produce a pasteurized solids fraction; microfiltering the liquid fraction through a microfilter having a size cut-off of 1 μm or smaller to produce a microfiltered liquid fraction; and combining the pasteurized solids fraction and the microfiltered liquid fraction to result in the filtered beverage.

Provided is a cell culture apparatus including a culture vessel that stores a cell suspension containing cells; a first filter part that has a first filter membrane that performs membrane separation treatment on the cell suspension extracted from the culture vessel; a first circulation flow path that allows components blocked by the first filter membrane to return to the culture vessel; a second filter part that has a second filter membrane that performs membrane separation treatment on components of the cell suspension permeated through the first filter membrane; a second circulation flow path that allows components permeated through the second filter membrane to return to the culture vessel; and a recovery flow path that recovers components blocked by the second filter membrane. In the cell culture apparatus, an average hole diameter of the first filter membrane is 20 μm or smaller, and 0<B/A≤0.5 is satisfied in a case where an average hole diameter of the first filter membrane is A and an average hole diameter of the second filter membrane is B; or an average hole diameter of the first filter membrane is 20 μm or smaller, and the second filter membrane is an ultrafiltration membrane.

Disclosed is a system and method for isolating large quantities of viable, undamaged exosomes from liquid, cell-free mesenchymal stem cell cultures using tangential flow filtration.

Disclosures herein are directed to first compositions comprising exosomes and extracellular matrix components and their use thereof. Also described are methods and kits wherein these first compositions are packaged and used with second compositions comprising mesenchymal stem cells. The first and second compositions are derived from the same tissue source using tangential flow filtration.

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.
