A modular, compact, mobile, dewatering and liquid-liquid separation and filtration system. The system processes incoming influents of slurries, solids and liquids at a high speed of operation and in large volumes. System is capable of being modularly scaled, allowing for a continuous steady state operation accommodating any slurry flow rate in a synchronous dynamic equilibrium process. Components and modules integrated into the system include a dynamic filtration clarifier 101 (DFC), a nested-filter dewatering cell 115 (NDC) and/or a compression filter press 125 (CFP). The DFC performs the primary dewatering phase of separating the primary water from the solids creating sludge. The NDC further breaks apart the solids of the sludge, removing interstitial water in a secondary dewatering phase, further lowering the moisture content of the sludge, while the CFP removes the tertiary water from the remaining solid particles by pressing the particles into a solid cake.

A device for filtering oil, including: a tank including an oil inlet and a cover; an at least one removable plate, inside the tank, that can be removed from the tank via the upper opening of the cover. The at least one plate removably receives filtering cartridges. The plate is hollow, forming a collector for the oil filtered by the cartridges of the plate. The plate includes an outlet for filtered oil removably connected to a corresponding outlet of the tank via a connector. The connection includes a first portion rigidly connected to the plate and a second portion rigidly connected to the tank, that are capable of mutually cooperating via a seal in order to provide a sealed connection between the oil outlet of the plate, and the corresponding outlet of the tank, and in order to allow maintenance operations to be performed without intervening in the tank.

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 application provides a sample collecting device and a sample collecting apparatus. The sample collecting device includes a housing assembly with a cavity and a filtering unit disposed in the cavity, where the housing assembly is provided with a collecting hole and a suction hole, both of which are communicated with the cavity, the suction hole is communicated with the collecting hole through the filtering unit, the housing assembly is provided with a gateway on its side wall, and at least part of the filtering unit is configured to be moved to an outside of the housing assembly through the gateway. The present application can greatly improve efficiency of sample collection and effectively save the time of medical workers.

A filter assembly includes a filter head and a filter cartridge. The filter head includes a filter head coupling surface, a filter head outlet, a filter head inner wall, and a filter head outer wall. The filter head coupling surface defines a filter head opening. The filter head outlet is configured to provide a fluid. The filter head inner wall extends around the filter head outlet. The filter head outer wall extends around the filter head inner wall. The filter head inner wall and the filter head outer wall collectively define a filter head channel. The filter cartridge includes a filter cartridge shell and a filter element. The filter cartridge shell has a filter cartridge coupling surface that is configured to be coupled to the filter head coupling surface. The filter cartridge shell defines a filter cartridge opening.
