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 mobile water purification system comprises a movable trailer, a storage tank positioned within the trailer, a water filtration and treatment system positioned at least partially within the trailer, a water dispensing system positioned at least partially within the trailer. and one or more solar panels coupled to the trailer.

A wetland system has a wetland structure and a wastewater treatment device. The wetland structure has several planting areas surrounded by hoardings, several planting frames arranged in the hoardings, growing substrates provided in the planting frames, and wetland plants growing on the growing substrates. The wastewater treatment device has a bar screen, a regulating tank, a hydrolysis acidification tank, a contact oxidation tank, an MBR membrane tank, and a clean water tank that are in communication with each other in sequence of waterflow and arranged underground. The bar screen is provided with several bars therein, a lift pump is connected between the regulating tank and the hydrolysis acidification tank, a drainage pump is provided between the MBR membrane tank and the clean water tan. The planting area is connected to the bar screen via pipelines, and the clean water tank is connected to the planting area via pipelines.

A method, system, and apparatus directed to an innovative approach for the treatment of stormwater utilizing hydrodynamic separator assembly designed to maximize flow movement for more efficient sediment removal and maximize water flow control.

A stormwater capture housing system designed to reduce greenhouse gas emissions by filtering solid waste from stormwater flow in roadways, transportation facilities, and pavement, while maintaining an optimal flow rate and enabling safe accessibility. The system comprises a housing unit with top grates that enable stormwater and solid waste to drain from the roadway into a sub-grade capture area formed by a screen weir and a screen box. The screen box ensures that the solid waste is collected while the water filters into a clean water area. The screen weir also filters solid waste and is further configured to allow for an overflow of stormwater and solid waste. Another section of the top wall has a filled grating configuration that allows for stormwater to drain without passing any solid waste to prevent flooding, also enabling access to the internal components of the housing system.

A rain head comprising a lower body, a screen and an upper body. The screen includes a frame having a trough or recess. Lower parts of the sidewalls of the upper body 14 can fit into the trough or recess to enable the upper body to be removably mounted to the rain head. The screen also includes a peripheral flange and a downwardly extending lip that enable the screen to be removably mounted to the upper part of the lower body. At least some water splashing off the screen during a rain event comes into contact with the upper body and is re-directed to flow into the lower body and out through the outlet of the lower body to a rainwater collection tank. The screen and upper body may be provided separately to the lower body.

Relatively greater capillarity material layers and relatively lesser capillarity material layers are provided. These layers can be used to promote capillary wetting in capillary wetting zones to promote prolonged periods of water retention. Carbon sources present in the capillary wetting zones may exhibit prolonged use provided by limited drying and wetting cycles experienced in the capillary wetting zones. Carbon sources positioned between saturated layers may exhibit prolonged use provided by anoxic conditions created by upper and lower water seals of the saturated layers. Capillarity layers can be employed in infiltration systems handling water, such as residential wastewater.

The present invention relates to a water-processing system configured to produce purified waste water. The system comprises an inlet for waste water, one or more biological water-treatment units, and an outlet for purified water. The one or more biological water-treatment units are fluidly connected to the inlet and the outlet. Each of the one or more biological water-treatment units comprises: an inlet for receiving water to be treated, a reactor, an outlet for treated water, and ventilation means configured to provide ventilation to the reactor. The reactor is divided into two or more compartments by one or more screens. Each compartment is in fluid communication with the ventilation means, and comprises a biofilm on one or more surfaces. The reactor is configured to expose at least a portion of the waste water to the biofilm in the presence of air supplied by the ventilation means.

One aspect of the present invention is directed to a granular filter media for removing contaminants from water or other liquids. The media comprise granular materials comprising aggregate and remediation materials. Other aspects of the invention are directed to methods of making and using the granular filter media of the invention.

An automatic rainwater collection system, with a high degree of autonomy and sensitivity, which allows the collection and use of rainwater, in open spaces, areas of difficult access and/or lacking of water extraction systems, as well as in domestic spaces such as gardens or roofs, without additional adaptations for its use and which works with solar energy. The automatic rainwater collection system is conformed by: a flower-shaped obturable rainwater receiving element, which comprises: a plurality of internal petals and a plurality of external petals that can be opened or closed in an automated manner, a sensor with high sensitivity to droplet impacts and/or relative humidity, which is operatively connected to a motor to control the opening and closing of the plurality of petals of the rainwater receiving element; a support frame, which functions as a support for the obturable rainwater receiving element and as a water storage media; a modular system for filtering water, connected to said central media of water accumulation, which comprises a plurality of filtering modules, which provide different filtering options depending on the quantity and combination thereof in order to obtain different qualities of water for use in several activities; and a water storage media, which further functions as base and support of the collection system.
