A fluid management system including an inlet configured to receive pre-processed fluid is provided. The system includes a filtering apparatus configured to remove contaminants from the pre-processed fluid. The filtering apparatus includes a plate having a first opening. A first manifold pipe is disposed on the plate and includes one or more perforations and a second opening at least partially aligned with the first opening. A second manifold pipe is disposed on the plate and includes one or more perforations. Filter media is disposed between the first manifold pipe and the second manifold pipe and is configured to separate the contaminants from the pre-processed fluid. The system also includes an outlet coupled to the second manifold pipe to receive processed fluid from the filtering apparatus.

A module for a wastewater treatment system, for use when buried in permeable media such as sand or soil, includes a central distribution unit and a multiplicity of treatment fins in flow communication therewith. Within each fin is a lengthwise-running perforated pipe. In one kind of assembly, a treatment system module comprises a central housing has attached fins which are wrapped in spiral fashion around the central distribution unit when in a compact shipping container. In another assembly, the fins are attached to a central membrane and shipped in a container while folded, detached from the central distribution unit; and the distribution unit may be comprised of separate nested half units to be joined at the point of use. When take to a wastewater treatment site, the packed components are removed from the container and arranged for use.

A horizontal flow water treatment method and wetland biofilter system with improved flow control via a tubular apparatus and further comprising a chamber with impermeable outer walls spaced away from permeable interior walls of a media filtration bed such that a catch basin is formed between the outer walls and the interior walls. The catch basin creates an open area around the perimeter of the interior walls for influent water to fill within the open area on all sides before penetrating the filtration media, providing a large surface area for influent water to interact with the media filtration bed. The influent water enters the catch basin in a horizontal flow path to provide for pre-settling of particulates before making contact with the filtration media. The biofilter design increases the available surface area of the media filtration bed by up to four times for a given volume of water, and thereby minimizes the loading or infiltration rate on the media filtration bed.

The present invention is a new process for preserving the water of an aquatic body as a supplying source for different human activities such as recreation and amusement, food and ornamentation, by the development of a aquatic space formed by a Open water Lake, a Spa Lake, and a Water Depuration Lake that preserves the water mass by biotransformation and mineralization that allow reducing the concentration of carbon, nitrogen and phosphorous, generating clean and transparent water without the use of large amounts of chemicals and complex filtrate systems.

A method for changing filler pollutant accumulation of a constructed wetland belongs to the field of environmental protection engineering. A coupling device of a microbial fuel cell and a constructed wetland is constructed by using active carbon as a constructed wetland filler, and pond sewage enters into the constructed wetland from the top of the device in an intermittent mode. A titanium mesh is taken as an electron collector for packaging a cathode of the active carbon filler by using the characteristic that electrons are collected by the titanium mesh in a concentrated mode, after stable operation for a period of time, active carbon close to a water surface and active carbon close to the bottom of the titanium mesh are taken out for carrying out specific surface area and biomass measurement, and the accumulation distribution condition of filler pollutants inside the constructed wetland is analyzed.

Disclosed is a recycling system for treating sewage of an ecological farm, including an external water source, a living area producing domestic sewage, a culture area producing breeding sewage and a farmland area producing agricultural drainage. The external water source feeds water to an ecological river, a water-saving irrigation system of the farmland area, the living area and the culture area through a water-diversion system. A first channel configured to discharge the domestic sewage from the living area is communicated with the water-saving irrigation system through a domestic sewage treatment system. A second channel configured to discharge the breeding sewage from the culture area is communicated with the water-saving irrigation system through a breeding sewage treatment system.

Systems and methods of restoring a lake including dredging, island creation, water treatment, real estate development, computer modeling of environmental conditions, wave height reduction, sediment removal and encapsulation, bathymetry contouring, littoral zone restoration, plant restoration, and/or fish restoration.

A wastewater sampling device configured to collect, for sampling purposes, a portion of an effluent and/or of treated wastewater released by a wastewater treatment system. The wastewater sampling device comprises a base and sidewalls configured to receive and channel the effluent and/or treated wastewater into a collection well whereby said effluent and/or treated wastewater may be subsequently collected by means of a collection chimney. The wastewater sampling device may be installed at any depth underneath the wastewater treatment system, thus allowing for a collection of effluent and/or treated wastewater at different stages within the filtering process.

Methods, apparatus, and systems involving wastewater treatment systems are provided. The descriptions include a wastewater conduit with a pair of curved infiltrative surfaces. These curved infiltrative surfaces pass wastewater from within the conduit to outside of the conduit.

Reconfigurable water leaching modules are provided herein. These modules may comprise a plurality of dosing conduits and a plurality of leaching channels fluidly coupled to the dosing conduits where the leaching channels are reconfigurable from a first retracted position to a second extended position and where the leaching channels may hang downwardly from the dosing conduits in the second extended position.
