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, a polymer dosage tank to provide a polymer dosage to the coagulated waste water to produce and output flocculated waste water. An air grid of the electrocoagulation unit, the latter housing a plurality of electrodes, increases the lifespan and efficiency of the electrodes to perform electrocoagulation of the 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.

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.

A coolant supply device includes a supply pump configured to supply a coolant of a clean tank to a machine tool, a recovering route configured to return the coolant from the machine tool to a dirty tank, a cyclone filter arranged on a coupling route and configured to separate the coolant into dirty liquid and a clean liquid, and a container connected to a dirty liquid outlet of the filter and configured to accumulate the sludge. The coolant supply device further includes a sensing unit configured to sense the amount of accumulation of the sludge in the container, and a controller configured to perform control based on a sensing result of the sensing unit.

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.

Settling devices for separating particles from a bulk fluid with applications in numerous fields. The particle settling devices include a first stack of cones with a small opening oriented upwardly or downwardly. Optionally, the settling devices may include a second stack of cones with a small opening oriented downwardly or upwardly. The cones may be concave or convex. These devices are useful for separating small (millimeter or micron sized) particles from a bulk fluid with applications in numerous fields, such as biological (microbial, mammalian, plant, insect or algal) cell cultures, solid catalyst particle separation from a liquid or gas and waste water treatment.

A method of separating heavy water from normal through application of acoustic pressure shock waves to a fluid including heavy water and normal water and recovering separated normal water.

A sludge dewatering tank that includes a first wall, a second wall, a third wall, a fourth wall and a bottom that cooperate to define a tank interior, a first interior wall and a second interior wall. The first interior wall cooperates with the first wall to define a first drainage compartment and includes at least a first filter member. The first drainage compartment includes at least a first drain that communicates the first drainage compartment with an exterior of the sludge dewatering tank. The second interior wall cooperates with the second wall to define a second drainage compartment and includes at least a second filter member. The second drainage compartment includes at least a second drain that communicates the second drainage compartment with the exterior of the sludge dewatering tank. The first interior wall cooperates with the second interior wall to define a sludge space therebetween.

A method to accumulate and pre-treat waste water prior to further processing. The method comprises accumulating waste water in a first and second tank and selectively adding further influent waste water to the first or second tank to such that the resultant pH from combining the influent waste water with the accumulated waste water results in a pH close to a target pH.

This disclosure relates to a bottom section for being connected to an assembly for separating a solid component from a fluid. The assembly includes an inclined plate settler with at least one sedimentation channel for letting a solid component to be separated settle, said plate settler comprising a lower portion and an upper portion, wherein said at least one sedimentation channel extends from the lower portion to the upper portion. The bottom section is configured to be connected to the lower portion of the inclined plate settler. The bottom section comprises at least one inlet channel for feeding a fluid comprising the solid component to be separated to the plate settler, and at least one collection channel for collecting a settled solid component descending from the at least one sedimentation channel. Said at least one inlet channel and said at least one collection channel are fluidly separated from each other, said inlet channel and said collection channel being connectable to said at least one sedimentation channel, to form fluid connections between said at least one inlet channel and said at least one sedimentation channel and between said at least one collection channel and said at least one sedimentation channel, respectively.

A system and method of cleaning a desanding vessel is provided including determining that sand has settled in the accumulation zone of the vessel, isolating and depressurizing the vessel and introducing a flush or wash fluid into the vessel. The wash fluid is introduced via a flush inlet at or near the process gas outlet of the vessel, and at a purge rate to fluidize sand in the accumulation zone and form a slurry. The slurry is collected from the vessel at a flush outlet downstream from the flush inlet. The purge rate is maintained for elutriation of the fluidized sand in the slurry, through the vessel and out of the flush outlet.
