An extrusion system for separating particulates entrained in wash water, e.g. from harvesting tuberous produce, includes a settling tank configured to receive a flow of particulated water. A diffuser suspended within the tank converts the flow of particulated water into multiple transverse flows to avoid churning settled particulates. A particulate filter fixed within the tank includes a central channel surrounded by a cylindrical array of cantilevered parallel vertical blades. The channel directs the flows below the blades, causing dynamic movement of the blades as the particulated water rises therebetween to trap particulates along boundary layers, promote particulate settling by gravity, and allow clarified water to rise to the top of the tank. A sensor detects settled particulate reaching a predetermined setpoint, and in response the system actuates an auger and opens a pinch valve to force concentrated particulate from the bottom of the tank.

The device comprises the thermal desorption system and a sewage treatment assembly connected with the thermal desorption system. The sewage treatment assembly comprises a particle precipitation tank for removing large particle suspended matters in sewage, a chemical purification tank for removing organic mattes in sewage and a filter tank for removing fine suspended matters in sewage, which are connected in turn, the particle precipitation tank comprises a stirring cavity provided with a stirring mechanism and a contaminant collection cavity, and the stirring mechanism comprises a stirring shaft provided with several groups of stirring blades along a length direction and a first motor driving the stirring shaft to rotate.

An electro-separation apparatus for separation of drilling fluids is provided. The apparatus can include a reaction chamber and a set of electrode plates provided in the reaction chamber. A sediment outlet can be provided near a bottom of the reaction chamber and wiper blades can be provided for sweeping sediment that has collected on the electrode plates towards the sediment outlet.

The instant launder cover is readily fabricated by pultrusion, vacuum bag, or other non-sprayed methods and may advantageously be used with various sizes of tanks and/or launder troughs. The cover system effectively controls odor using, for example, optional gaskets while not requiring stiffening flanges or interfering with wiper mechanisms or other components of the tank or system.

A clarifier can comprise a floor, inner and outer walls that each extends upwardly from the floor such that a tank is at least partially defined by the inner wall and a launder channel is at least partially defined between the inner and outer walls and is disposed along at least a majority of a periphery of the tank. A launder cover comprising one or more flexible sheets can be disposed over at least a majority of the launder channel. Each of the sheet(s) can have opposing inner and outer edges, the inner edge coupled to the inner wall and the outer edge coupled to the outer wall, and can be configured such that, when a single one of the inner and outer edges is decoupled from the inner and outer walls, the sheet is deformable to at least partially uncover the launder channel.

A launder cover system for reducing or eliminating sunlight exposure so as to prevent algae growth in a tank such as a clarifier tank. The launder cover system generally includes a plurality of support members and a plurality of launder covers which are each independently pivotably connected to a tank wall of a tank, such as by using a mount. The support members are each pivotably connected to the tank wall by a pivot connector and the launder covers are each pivotably connected to the tank wall by a hinge connector. Each support member is positioned between a pair of launder covers, and each launder cover is positioned between a pair of support members. The support members function to support the launder covers in a raised or lowered position. A launder support may be connected to the channel wall to support the launder covers in their lowered positions.

The invention relates to a storm water drain pit comprising: an inlet for storm water; a filter for removing particles from the storm water, comprising a cylindrical body comprising coherent man-made vitreous fibres (MMVF) bonded with a cured binder composition; wherein the cylindrical body has a hollow centre and an outer wall; a guide element for guiding water from the inlet into the cylindrical body; a sedimentation chamber for sedimentation of particles from the storm water, wherein the cylindrical body is positioned below the inlet and above the sedimentation chamber; an outlet for filtered water; wherein the outlet is positioned above the sedimentation chamber and below the inlet; and a separation element for separating the sedimentation chamber from the outlet; wherein the cylindrical body has a density in the range of 50 to 200 kg/m.sup.3, a binder content in the range of 2 to 5 wt % and the outer wall has a circumferential thickness in the range of 2 cm to 20 cm.

The present invention provides a multiphase separator for separating a multiphase fluid produced by one or more oil wells, the multiphase separator comprising: a separating vessel, comprising an inlet chamber and an oil chamber for collecting oil at least partially separated by a barrier; an inlet for introducing the multiphase fluid into the separating vessel; wherein the oil chamber is positioned on the opposite side of the barrier to the inlet; a gas outlet configured to collect gas separated from the multiphase fluid; an oil outlet configured to collect oil, separated from the multiphase fluid, from the oil chamber; a water outlet configured to collect water separated from the multiphase fluid; and a gas and water mixture injector configured to inject a mixture of pressurized gas and water in a lower portion of the separating vessel.

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 to a flow line, a polymer dosage tank to provide a polymer dosage into the flow line where the polymer dosage mixes with the coagulated waste water to produce and output flocculated 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 separator system includes a separator including an inlet configured to receive a mixed fluid, a first outlet, and a second outlet. The separator system includes a pressure tank physically coupled to the separator, and including a partition wall defining a collection chamber and a separation chamber in the pressure tank, a first inlet communicating with the collection chamber and coupled to the separator to receive at least some of the solids component from the separator, and a second inlet communicating with the separation chamber and in communication with the separator. The second inlet is configured to receive at least some of the liquid component and the gaseous component from the separator. The pressure tank also includes a first drain in communication with the collection chamber, and a first liquid outlet in communication with the separation chamber. The pressure tank includes a gas outlet in communication with the separation chamber.
