A modular system for treating septic tank wastewater using substrates that support multiple biohabitats is lowered into a septic system where untreated wastewater enters the system from an opening defined by the lower region, travels upwardly through a bioremediation chamber containing a substrate oriented to form at least one vertical path, and treated wastewater exits through an opening defined by the upper region. An aerator positioned below the lower opening sends a stream of bubbles upwardly, thereby urging untreated wastewater upwardly into the bioremediation chamber. A mixer positioned below the lower opening intermittently emits large air bubbles that dislodge biomasses that accumulate on the substrate. A variety of microbiological processes occur on the surfaces and within the recesses of the substrate.

A moving bed assembly for use in an aqueous environment includes a frame housing, a retention screen coupled to the frame housing and extending at least partially across one side of the frame housing, where the frame housing and the retention screen cooperatively defining an interior of the moving bed assembly, and biocarrier media retained within the interior. The assembly further includes a diffuser coupled to the frame housing and configured to direct bubbles into the interior of the housing to agitate the media within the interior when the assembly is in the aqueous environment. The assembly has a density greater than a density of fluid in the aqueous environment such that the moving bed assembly is configured to be submerged and a fill ratio of a volume of the biocarrier media to a total volume of the interior of the moving bed assembly is between 30% and 70%.

A reactor for treating water, the reactor comprising a buoyant structure for supporting at least one cell for suspension in a body of water in use, wherein each cell is removeably attachable to the buoyant structure and is arranged to house biomedia. A water treatment system comprising the reactor in a body of water. A method of treating water comprising passing water to be treated through the reactor in a body of water.

In some embodiments, a wastewater treatment system may reduce contaminants in water. A system may include one or more bioreactors which include a substrate that supports a biofilm. The bacteria used to form the biofilm may be selected to maximize the reduction of contaminants in water. Various components of the wastewater treatment system may be optimized to improve the efficiency and energy consumption of the wastewater system.

Utilizing mobile walls, a transportable (or stationary) low cost, low carbon footprint process and apparatus with a granular filter media dry cell (for filter or bed) for dewatering particulate solids from liquid. The mobile wall structures can be made of a rigid structure constructed of new or preferred salvaged materials, assembled, with watertight joints, used, disassembled and stored for redeployment. The walls are set in a keyway utilizing whatever soil composition is available. The walls can be used in the previous Deskins filters as old wall replacement or new wall construction. The invention utilizes a generator that is not dependent upon site or local electricity thus can be operated in any location. All parts can be engineered, fabricated according to the design of the Quick-Dry Filter Dewatering Mobile Process and Apparatus, packed in shipping containers and be readily available for any immediate need.

An aeration and microbial reactor system for use in decontaminating water including a housing adapted to float and/or submerged within the medium such that a top portion thereof remains adjacent a top surface of the contaminated water while the bioreactor containing inoculated carrier media is attached below. Beneficial microbial populations thrive and spread throughout the liquid medium, and consume or fix the contaminant such that the contaminant is removed from the water.

Equipment and a method for on-site and ex-situ modulation of microbial consortia useful in liquid and semi-solid effluents or solid waste treatment systems, for removing and/or reusing undesirable organic or inorganic loads. The equipment has of a main cultivation tank or a liquid body provided with an ex-situ subsystem for modulating microbial consortia for subsequent or concomitant introduction into the main cultivation tank or reactor or into the liquid body. The process is implemented in a culture equipment with controlled conditions for introducing the microorganism-enriched material into the effluent or solid waste to be treated, in the form of pre-cultivation and/or co-cultivation. The ex-situ subsystem of the invention has a device for forming gas/air bubbles in a liquid suitable for applying a shearing force to the microorganisms present in the subsystem, and also useful for modulating the microbial consortia in a main cultivation tank or a liquid body.

A system for cleaning and sterilizing a water flow comprises a main treatment line with a pump to pump water from a water storage, a main filter, a sterilizing station and a system outlet. The main filter is provided with a first filter element and a backflush member to rinse the first filter element with backflush water. The secondary treatment line connects to an outlet of the backflush member, and has a backflush filter to remove silt from the backflush water. The main filter is designed such that the pressure difference over the, first filter element is at least 0.1 bar (10 kPa) and the backflush filter is designed such that the pressure difference over the backflush filter element is less than 0.05 bar (5 kPa).

In one embodiment, a portable wastewater treatment system includes an anaerobic reactor in which organic material within the wastewater can be broken down, a membrane filter that receives wastewater from the anaerobic reactor and filters the water to produce permeate, and a small shipping container in which the reactor and the membrane filter are contained.

A system and method includes an aeration subsystem that excites enzymes in the liquid waste passing through the septic system. The aeration subsystem includes a compressor section that compresses the liquid waste. The method includes mixing enzymes into the fluid waste material, compressing the fluid waste material with the compressor, injecting air into the compressed fluid waste material, and determining whether the fluid waste material is at a desired cleanliness, and if not, recirculating the fluid waste material through the compressor.
