A system for removing sedimentary solids from a separator is provided. The separator is for separating components of well fluid produced by a well. The system includes an inlet for receiving motive fluid; a nozzle configured to introduce the motive fluid to the sedimentary solids in the separator, thereby fluidizing the sedimentary solids; and an outlet configured to allow the fluidized solids to exit the separator. The motive fluid includes well fluid produced from the well. A separator, method for removing sedimentary solids from a separator, and method of removing solids from well fluid produced by a well are also provided.

Sand separation systems and methods according to which one or more energy sensors are adapted to detect a response to energy imparted to a sand separator of a known type. One or more computers are adapted to communicate with the one or more energy sensors. The one or more computers and/or the one or more energy sensors are pre-tuned. The one or more computers are configured to determine the unknown sand level in the sand separator of the known type based on: the response detected by the one or more energy sensors, and the pre-tuning of the one or more energy sensors and/or the one or more computers.

An installation for treating a wastewater effluent in a constant-level sequencing batch reactor (SBR), the SBR includes a chamber that is able to contain a mixture of wastewater and sludge comprising different levels, each level being defined by a concentration and/or a density of sludge, a sludge bed situated at the bottom of the chamber, a device for supplying the SBR with a volume of effluent to be treated close to the bottom of the chamber, in the sludge bed, preferably via a distribution network covering the bottom of the chamber, means for recovering a clarified fraction of the contents of the chamber, the SBR being able to implement a treatment method comprising a biological treatment reaction sequence comprising at least a step of aerating the contents of the chamber, during which the level of the surface of the mixture rises, a decanting step, during which sludge is deposited on the bottom of the chamber and the contents of the chamber are clarified close to the surface thereof, a step of recovering the clarified fraction of the contents of the chamber, the recovery step and supply step taking place simultaneously, so as to keep the level of the contents of the chamber substantially constant during the recovery step and supply step, the installation also comprising control means and recovery means.

A compact hydraulic particle separator apparatus is disclosed. The disclosed apparatus comprises an upper chamber and a lower chamber separated by a partition. A liquid fluid flow upwelling through the partition from the lower chamber is caused to mix with tangential jet of fluid flowing introduced above the partition in the upper chamber produces an upwardly-flowing cyclonic flow within the upper chamber. Particle mixtures containing low- and high-density particles and other solids are introduced into the upper chamber through a feed tube having a mouth that is offset from the center of the upper chamber. Low-density particles are immediately entrained in the cyclonic flow and swept upward and exit the apparatus.

An apparatus for reducing the water content of waste water sludge includes a column for receiving waste water sludge, an outlet at a lower end of the column, a first closure for closing the outlet of the column, a controller for controlling the opening and closing of the closure. The controller is adapted to open and close the first closure to periodically discharge amounts of settled fines from the lower end of the column. A water outlet is adapted to receive water overflowing from an upper end of the column.

A system for automatically discharging sand from a sand separator. The system includes a first and second valves and a choke valve disposed in a discharge line from a sand separator. A pressure transducer measures pressure in the line between the first and second valves. A controller operates the valves to initiate and terminate the discharge sequence. An emergency shutdown valve is positioned upstream of the sand separator and is operative to shut down the system if the pressure reading by the transducer exceeds a predetermined amount.

A separating system, for example for separating material from a suspension such as a biological suspension, is disclosed herein. The system comprises a separation vessel arranged to enable the formation of a cyclone therewithin. For example, the separation vessel may be at least partially conical in shape for enabling the formation of a cyclone therewithin. The separation vessel comprises a fluid inlet, an underflow outlet and an overflow outlet. The system also comprises at least one of an underflow outlet fluid control means for controlling the flow of fluid through the underflow outlet, and an overflow outlet fluid control means for controlling the flow of fluid through the overflow outlet. The system may further comprise an inlet fluid control means for controlling the flow of fluid through the fluid inlet.

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 frac sand separator system includes a sand separator having an inlet fluidly connected to a well for receiving a fracking return mixture from the well. The sand separator is configured to separate water of the fracking return mixture from particulate matter of the fracking return mixture. The sand separator includes an outlet. The frac sand separator system includes a collection container fluidly connected to the outlet of the sand separator for receiving the particulate matter from the sand separator. At least one outlet valve is fluidly connected between the outlet of the sand separator and the collection container. The frac sand separator system includes a computing device operatively connected to the at least one outlet valve. The computing device includes a processor configured to automatically open the at least one outlet valve such that the particulate matter is released from the sand separator into the collection container.
