The “sludge dehydrator” equipment is a machine that permits to remove low turbidity water from sludge or watery pastes of industrial or mining origin, with the following objectives: To optimize ore recovery processes such as flotation by means of an increase of the sludge density; To thicken sludge or watery pastes for optimizing the filtering and drying processes, as well as to dispose of mining tailings; To concentrate and dispose of solids in suspension and to recover and recycle clean or clarified water. The “sludge dehydrator” equipment has been designed on the basis of a rectangular tank provided with the necessary infrastructure for containing inside a series of suction plates being connected to a vacuum system, through which the process of solid-liquid separation is carried out and, on the other hand, to contain the cleaning mechanism—the cleaning car—with its motor system made up by pneumatic or hydraulic components required to clean suction plates the filtering medium and to keep them permanently operative. In accordance with the “sludge dehydrator” feeding and the design of the lower or bottom cone of the rectangular tank will benefit to be derived from the industrial and mining operation.

A urea water tank (11) is provided with a unit insertion opening (12H) that is disposed on a top surface part (12A) of a tank body (12) and opens more largely than an external dimension (D2) of a sensor unit (20), a sensor mounting member (16) that is disposed on the top surface part (12A) of the tank body (12) and closes the unit insertion opening (12H), and a filter which is formed as a tubular body to surround the sensor unit (20), and inserted in the unit insertion opening (12H) of the tank body (12) from a lower end (24A4)-side, and having an upper end (24A3) mounted on the top surface part (12A) of the tank body (12) by using the sensor mounting member (16).

A capacitive sensor and control system is configured to detect the presence (or absence) of a filter pan and of fluid within a filter pan. Configured in a filter pan of a deep fryer, the sensor determines when a level of liquid within the filter pan is at or above the level of the. The sensor is in communication with the control system and the sensor sends a signal to the control system representative of the presence of liquid within the filter pan and at the level of the sensor. The controller receives the signal from the sensor, and allows operation of a fluid management system and its associated plumbing to completely and safely move oil into and out of the filter pan.

Self-cleaning inline filters that utilize sensors to measure pressure differential and activate a self-cleaning mode are disclosed. In the self-cleaning mode, the self-cleaning inline filters of the present disclosure utilize back, reverse, and/or counter-current fluid flow to separate two filter elements. The back, reverse, and/or counter-current fluid flow also flushes particulates out of the filter, such that the particulates are captured by a mechanical trap.

In a wastewater treatment plant a rag seeding tank is included in a process drain to collect hair and fibers which have passed through headworks of the plant. The hair and fibers tend to join together into large masses downstream of the headworks and can be damaging to process zones, particularly membrane zones. The rag seeding tank includes cartridges filled with surfaces that fibers and hair will attach to, so that hair/fiber rags grow in the seeding tank and are removed therefrom rather than causing problems downstream.

A filtration apparatus is provided. The filtration apparatus includes a housing and a plurality of filtering sheets. The housing is enclosed by a first end cap and a second end cap. The first end cap includes a liquid inlet, and the second end cap includes a liquid outlet. The plurality of filtering sheets is disposed on an internal sidewall of the housing. A portion of the filtering sheets interlaces with another portion of the filtering sheets to form a winding flow path in the housing.

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.

A filter pulsation dampening device has a replaceable filter element including a plurality of baffles disposed next to each other or a flexible valve that is disposed proximate a baffle.
