A method and equipment for removing ammonia nitrogen from electrolytic manganese residue are provided in the technical field of solid waste resource utilization. The method includes following steps: step 1: adding phosphate and magnesium salt into electrolytic manganese residue leachate and fully reacting, where after the phosphate and the magnesium salt are added, n (Mg):n (N):n (P)=1.1-1.3:1:1 in the electrolytic manganese residue leachate; step 2: on a basis of the step 1, adjusting pH of the electrolytic manganese residue leachate to alkalinity, and stirring and reacting for 10-30 min; and step 3: on a basis of the step 2, filtering the electrolytic manganese residue leachate to obtain purified leachate and struvite respectively.

A wastewater treatment device including: a vessel having an inlet for receiving an influent stream; and a separator disposed within the vessel. The wastewater treatment device further including: a grit pot connected to the separator; a level sensor configured to output a signal indicative of the level of grit within the grit pot; one or more fluidizing nozzles disposed within the grit pot and configured to deliver a jet of fluid from a fluid supply to fluidize grit accumulated on the lower surface of the grit pot; an extraction outlet connected to a pump for extracting grit fluidized by the fluidizing nozzles; and a controller in communication with the level sensor, wherein the controller and the pump are configured to activate the fluidizing nozzles based on the signal received from the level sensor. There is also described a wastewater treatment device including: a vessel having an inlet for receiving an influent stream; and a separator disposed within the vessel. The wastewater treatment device further including a grit pot connected to the separator, a level sensor configured to sense the level of grit within the grit pot, and a support extending into the grit pot from outside of the grit pot. The level sensor may be movably connected to the support and is movable along the support between an operating position in which the level sensor is positioned within the grit pot and a maintenance position in which the level sensor is positioned outside of the grit pot so as to be accessible by a user.

A method and apparatus for conditioning the settled solids in the bottom of a wastewater filtration tank to reduce the acidification of the sludge and prevent the excessive growth of undesirable biological growth.

A nozzle is provided for a header conduit. The nozzle includes an inlet that is resistant to clogs caused by flat materials covering the inlet. The inlet generally includes multiple pathways to an elongated passageway through which waste liquid and sludge (“waste”) are guided and enter the header conduit. In one embodiment, the elongated passageway is oriented to guide the waste along a path that is tangential to at least the inner surface of the header conduit which such incoming waste first contacts. When the conduit has an inner surface of circular cross-section, the passageway may optionally be elongated enough that the incoming waste enters the header conduit along a path tangential to the circular surface. To better assure axial flow of the waste in the conduit to an outlet, in one embodiment the passageway provides both the tangential flow and is at an acute angle to the longitudinal axis of the conduit. The incoming waste is thereby provided with an axial component. In this manner, the passageway assures that the energy and momentum of the incoming waste is helical in direction. The waste previously admitted into the header conduit is urged by the newly entering waste to continue to flow helically in the conduit. The passageways are provided at spaced intervals along the length of the conduit to collect sludge from a wide area of the bottom of the basin. Because of the tangential orientation of each of the passageways and the resulting initial tangential flow of the incoming waste, the waste incoming from each of those multiple passageways reinforces the existing helical flow of waste in the conduit.

A tank assembly for the treatment of waste streams that include settling pollutants and floating pollutants. The tank assembly includes an inlet conduit, a first compartment that includes a first drain at a bottom thereof, a second compartment that includes a second drain at a bottom thereof, a third compartment that includes a third drain at a bottom thereof, and an outlet conduit. The second compartment also includes at least a first lamella filter package disposed therein. The third compartment also includes a skimmer, an underrun member and an overrun member. A liquid flow path is defined from the inlet conduit, through the first compartment, through the second compartment and the first lamella filter pack, through the third compartment, past the skimmer, under the underrun, over the overrun and out the outlet conduit.

A transportable separation apparatus for separating spent materials from oil and gas operations into a primarily solid component and a primarily liquid component. The separation apparatus includes a first separation area disposed on the separation apparatus for receiving spent materials and beginning separation of the spent materials. The separation apparatus designed to be connected to a vehicle to be pulled on commercial roadways. The separation apparatus also includes a second separation area in fluid communication with the first separation area for further separation of the spent materials. The separation apparatus can further include an auger in fluid communication with the first separation area to remove the primarily solid component from the separation apparatus. A method of introducing and separating the spent materials via the separation apparatus.

Removable trap stations for hydrocarbon flowlines can be implemented as an apparatus. The apparatus includes a multi-phase fluid receiver body and a tank defining an interior volume. The fluid receiver body is configured to couple to a flowline carrying a multi-phase fluid including solids and liquids. The fluid receiver body includes an inlet portion configured to receive a portion of the multi-phase fluid including a portion of the solids flowing through the flowline into the receiver body. The fluid receiver body includes an outlet portion fluidically coupled to the inlet portion. The portion of the multi-phase fluid is configured to flow from the inlet portion to the outlet portion. The tank is fluidically and detachably coupled to the outlet and is configured to receive and retain the portion of the multi-phase fluid received through the inlet portion.

The present disclosure is directed toward a suction nozzle operable to remove solid contaminants from a fluid without causing a substantial increase in fluid resistance. The suction nozzle has a vertical flow path, a contaminant precipitation recess opened upward under the vertical flow path, and a lateral flow path extending laterally from the vertical flow path at a position above the contaminant precipitation recess. The fluid sucked from a suction opening in the lower surface is led to the vertical flow path through the lateral flow path and flows upward through the vertical flow path to reach a connection port. With fluid flowing through the vertical flow path, solid contaminants contained in the fluid settle down by gravity and precipitate in the contaminant precipitation recess and are separated and removed from the fluid.

Vaults, boxes, systems, and methods of treatment systems to capture pollutants from storm water runoff and prevent the conveyance of these pollutants from entering a receiving water body or landscape area, which is designed to be a part of a local permanent storm water drainage infrastructure. A single treatment box, vault and system combines both drainage conveyance, multi-level treatment techniques, variable hydraulic capabilities, and easy and inexpensive methods for servicing the system. A flow spreader having a triangular shape with straight sides, or concave sides or convex sides can split incoming water to pass into dual screen filtration systems. Additionally, an upwardly angled debris ramp above a downwardly angled screened defector can be located on both sides of the flow spreader to help direct debris and trash into dual screened boxes. The system can also include components selected from a shelf beneath the spreader, at least one baffle, skimmer, deflectors, media filtration and hydroslide water pressure lines with spray heads for cleaning debris on a sloped floor.
