Wastewater is received at an inlet of a nested coil of tubing. The nested coil of tubing includes an outer coil of tubing and at least one inner coil of tubing. The nested coil of tubing includes at least one of protrusions or filaments within an interior of the nested coil of tubing. The filaments or protrusions are radially arranged within an interior of the tubing, and microbial growth that is configured to treat the wastewater is disposed on at least portions of the interior. The wastewater is flowed through the nested coil of tubing. The microbial growth treats the wastewater to remove at least portions of sanitary waste in the wastewater. The treated wastewater is flowed through an outlet of the nested coil of tubing.

A wastewater management system includes a series of water treatment modules to treat wastewater and produce reusable and/or potable water and other beneficial byproducts of the wastewater treatment process. A pretreatment module, a filtration module, an evaporator module, an odor control module, a UV-light module, an autoclave module, a sonolysis module, an ozone module and a chlorination module are combined in multiple combinations along with holding tanks, condensers, flash tanks and other components to address water purification and reclamation needs based upon specific wastewater conditions. The system captures condensate from AC systems and rainwater from rainwater gutter systems processes the water to produce reusable and/or potable water with or without re-mineralization. Any CO.sub.2 produced by the water treatment system is captured and processed using naturally-occurring flora. The wastewater treatment system includes multiple closed-loop subsystems to minimize energy usage and maximize water purification and reclamation for reuse.

The invention provides an efficient system for treating livestock waste, particularly waste from cattle or pig farming. The new facility and method employ special transfers of slurry streams through ASBR, SBR, and a unique pretreatment reactor, resulting in treated water, quality compost, and biogas.

A mobile wastewater treatment system wherein a mobile carrier has mounted thereon a wastewater treatment plant. The wastewater treatment plant has a flow equalization tank, an aeration tank, a clarifying tank, a disinfection stage, and a pumping tank. The mobile carrier can be a trailer, a skid, a shipping container, or the like.

The invention concerns a wastewater treatment plant and a method for it. The plant comprising at least one main reactor module (30) having a plurality of stackable filter-modules (50), each filter-module purifying wastewater independently by being individually charged batchwise with wastewater. The wastewater is discharged on each filter-module by means of a deflector (44) referenced to a filter-module (50), the deflector creating a back pressure in dependency of the gravity-flow-force of the wastewater leading to that the wastewater is spilled from the deflector (44) in an angle of discharge relative to a horizontal plane evenly onto every independent filter-module, respectively.

The present disclosure provides for a method of filtering pollutants from a contaminated fluid stream. The method includes disposing unprepared humic shale in a container, contacting the unprepared humic shale with an aqueous solution, maintaining the aqueous composition in contact with the unprepared humic shale for a period of time, drying the humic shale, and then placing polluted water in contact with the humic shale until pollutants have been removed from the fluid.

A modular system for reducing the total suspended solids of waste, including scum, sludge and water layers, includes a plurality of chambers each being connected in succession by a corresponding one of a plurality of flow pipe segments including an inlet segment, an outlet segment and at least one middle segment, wherein the waste enters the septic tank via the inlet segment and is transferred between each of the plurality of chambers via the at least one middle segment; a corrugated flow pipe in fluid flow communication with the outlet segment; and the corrugated flow pipe being sized and configured for use as a settling zone for removal of a portion of the total suspended solids and wherein an amount of water from the water layer within the chamber adjacent the outlet segment enters the corrugated flow pipe and passes through the outlet segment.

An upflow continuous backwash deep bed sand filter (UCBF) having a recycle line for returning carbonaceous denitrifying bacteria attached to biomass to the influent of the UCBF. The recycle line returns the biomass to the treatment process at a location upstream of the upflow continuous backwash filter. Further, a liquid level control unit is provided that reduces fluctuations and significant drop in the liquid level upstream of the upflow continuous backwash filter, thereby avoiding or minimizing flow turbulences, air induction, and undesirable wastewater aeration resulting in the need to dose excessive carbon source to remove dissolved oxygen in the aerated wastewater.

A method of treating wastewater is disclosed in which a flow equalization reactor is provided that includes at least one wastewater treatment zone. A first wastewater treatment process is performed in the at least one wastewater treatment zone, which can be switched to a second wastewater treatment process. The flow equalization reactor is designed with a variable liquid depth and volume that can operated as a mixed wastewater zone, an anaerobic reactor zone, an anoxic reactor zone or an aerobic reactor zone. The equalization reactor provides sufficient variable liquid depth and volume above a minimum liquid depth and residual volume to provide the necessary hydraulic flow equalization or surge volume to achieve a relatively constant effluent pumping rate or feed forward flow rate over 24 hours per day, seven days per week into the downstream biological treatment processes, clarifiers, filters, or disinfection units, etc.

There is described a bioreactor comprising a perforated tube for inputting wastewater therein, a textured wall, such as a geotextile membrane, and an oxygenating unit comprising a pressurized air bubble diffuser. The wall is spirally installed around the perforated tube, defining a passageway fluidly connected to the perforated tube and along which the wastewater inputted in the perforated tube is forced to travel. The membrane is adapted for hosting aerobic bacteria at a surface thereof. The oxygenating unit is provided at a bottom of the passageway for oxygenating the passageway. The bioreactor can be included in a treatment apparatus comprising primary treatment chambers and a decantation chambers, forming a standalone unit which is compact and easy to install.
