A convertible filtration system for use with cartridge filters and bag-type filters for filtering contaminated fluids comprising a filtration system housing, a base attached to the filtration system housing, and a lid mechanism for generating sealing pressure between the lid mechanism and the filtration system housing. The filtration system housing includes a basket support flange and an integral basin for accommodating both cartridge and bag-type filters. When fluid is introduced into the filtration system housing through one or more fluid inlet ports, the basket support flange and integral basin additionally serve to prevent contaminated fluids from contaminating any filtered fluids that exit the filtration system housing through one or more fluid outlet ports.

A bag-shaped filter has a durability higher than that of a bag-shaped filter of the related art without an increase in costs such that the replacement frequency can be lowered. Further, the bag-shaped can capture smaller solids compared to a bag-shaped filter of the related art such that high filtration performance and durability can be achieved simultaneously. A bag-shaped filter is used to filter waste liquid including solid components, wherein the filter is a bag-shaped circular knitted fabric, a part or the whole of which is obtained using a fiber material at least a part of which is an elastic yarn, and a portion formed by at least doubly knitting a knitted fabric is provided in a bag-shaped bottom portion.

Containers for separating microcarriers from a cell culture fluid that offer a greater efficiency of filtration of cell culture fluids containing microcarriers relative to systems described in the art. The container may include a first compartment that may include a sterile collapsible bag, an inlet port providing a fluid path into the first compartment and an outlet port providing a fluid path exiting the first compartment; and a second compartment fluidly connected with the inlet port of the first compartment and including a plurality of independent or discrete microcarrier receiving regions defined by boundary walls which are partially or fully porous and having a porosity sufficient to retain the microcarriers inside the second compartment, while allowing the cell culture fluid to pass through the second compartment into the outlet port of the first compartment, where the cell culture fluid can be collected.

A method for separating microcarriers from a medium includes transferring a suspension that includes medium, microcarriers and cells into a compartment of a filter assembly. The filter assembly includes: a container having an interior surface bounding the compartment; and a filter having a tubular stem with an encircling sidewall extending between a first end and an opposing second end, the first end being secured to the interior surface of the container and the second end projecting into the compartment of the container, a plurality of openings extend through the sidewall of the stem that are large enough to allow the medium and cells to pass therethrough while preventing the microcarriers from passing therethrough. The medium and cells within the compartment are allowed to pass through the plurality of openings of the filter while the microcarriers are retained within the compartment of the container.

A removable catch basin filter insert includes a filter container is fitted into a catch basin in the ground at the location where the stormwater exits the gutter and enters the stormwater sewer system. The removable catch basin filter provides pollution capture from stormwater while being easily cleaned. A hinged cover is included at the top of the filter insert to allow the captured pollutants to be evacuated through the use of a vehicle or being tipped nearly upside down by a mechanical arm. A hinged trap door is included at the bottom of the filter insert to allow captured pollutants to be evacuated through the bottom of the device and into a container. By capturing the pollutants with the removable catch basin filter insert before the pollutants enter the mainline storm drain system, clean storm drain systems are provided allowing for cleaner waterways.

The present invention provides for a method for obtaining an oil extract of cannabis. The method includes: (a) contacting cannabis biomass and an edible oil; (b) pressing between a pair of plates to provide spent cannabis and an oil extract of cannabis; and (c) separating the spent cannabis biomass and the oil extract of cannabis.
