A filter assembly for separating microcarriers from a fluid medium includes a collapsible container bounding a sterile compartment adapted to hold a fluid. An inlet port is attached to the container through which fluid flows into the compartment. An outlet port is attached to the container through which fluid flows out of the compartment. A filter is disposed within the compartment, the filter dividing the compartment into an inlet chamber that is fluidly coupled with the inlet port and an outlet chamber that is fluidly coupled with the outlet port, the filter allowing a medium to pass therethrough but preventing microcarriers disposed in the medium from passing therethrough.

A portable water-purifying pouch is provided that includes a pouch-shaped body comprising an inlet part, through which water to be treated is introduced, and an outlet part, from which drinking water obtained by filtering the water being treated is discharged and a pouch-shaped filter medium, which is provided inside the body so as to hold and filter the water being treated, which has been introduced into the body, and comprises a fiber web layer having the structure of a three-dimensional network formed of nanofibers. The portable water-purifying pouch allows a large flow rate of drinking water to be obtained in a short time while filtering, with significantly superior efficiency, foreign substances such as bacteria and harmful germs in the water being treated merely by self-weight or by lightly applying pressure with a hand to the water being treated.

Methods, devices and systems for treating liquid utilizing an in-line filter having a filter bag positioned within a cage contained in an exit sub-chamber of a housing, the exit sub-chamber isolated from an inlet sub-chamber by a baffle, and an end cap to alternatively seal the inlet sub-chamber so that in one mode the device may function as a screen having an exposed filter bag when the exit end of the device is connected to a suction side of a pump and in another mode as a closed vessel where the end cap is connected to a discharge of a pump or in a further mode where the exit end is connected to a suction side of a pump. The low profile, lightweight, inline filter device provides for versatility and a much needed filter device for two modes of connection to a suction side of a pump while also able to connect to a discharge side of a pump.

A filtration system includes a pre-filter device configured to strain contaminants from liquid. The pre-filter device includes a strainer body, a strainer sleeve secured to the strainer body, and a fastener configured to pass through the strainer sleeve to secure the pre-filter device to a container.

A disposable dental waste filter device has a body having a receiving end, and a separable cap having a tip end, the body for receiving and capturing therein amalgam that enters into the body through the tip end and the separable cap. A disposable dental waste filter device also has a body having a receiving end, a central lumen for receiving and capturing amalgam, a filter, and a circular leg portion having an exterior channel, and a separable cap having a tip end, a circular outer rim having a circular end ridge portion with the ridge portion adapted to be inserted into the exterior channel of the body for a snap fit engagement between the cap and the body, the body for receiving and capturing therein amalgam that enters into the body through the tip end and the separable cap.

An erosion, sediment and pollution control product comprises a geotextile which includes at least 10% non-plastic non-biomass based inert threads, in particular basalt or glass threads, and cellulose based filler within the tubular geotextile. The geotextile may be knitted. A method of making a tubular knitted geotextile comprises the steps of: supplying non-plastic, non-biomass based inert threads, such as basalt or glass threads, to a circular knitting machine and knitting a tubular substrate which includes at least 10% non-plastic non-biomass based inert threads.

A paint strainer assembly includes a bucket that has a top edge defining an opening into the bucket to facilitate liquid paint to be poured into the bucket. A cylinder is insertable into the bucket and the cylinder has a ridge extending outwardly from the cylinder. The ridge rests on the top edge of the bucket when the cylinder is positioned in the bucket. A mesh bag is insertable through the cylinder such that the mesh bag extends into the bucket when the cylinder is positioned in the bucket to filter particles from a liquid paint when the liquid paint is poured through the mesh bag and into the bucket. A ring is positionable around the cylinder for retaining the bag on the cylinder when the bag is extended through the cylinder.
