An algae scrubber system operates via a flow of water and a power source. The algae scrubber system does not require a bubbler. The rate of flow of the water may be variable. The algae scrubber system includes a screen that is configured to be removed from the system without shutting off the flow of water through the system and without spilling the water. The system includes a main body with a water distributor providing water to a tray. A screen hangs from the tray to and grow light(s) encourage algae growth on the screen.

A scalable phytoremediation system that uses rock medium supporting a Salicaceae (poplar or willow) tree rhizosphere in a basin with controllable volume and water depth that results in tertiary treatment requirements for organic BOD, pathogens, ammonia-nitrogen, nitrate-nitrogen and phosphorous pollutants and PFAS. COC removal is achieved by pollutant sorption, plant uptake and increased microbial mineralization activity. Phyto basin achieves faster pollutant mineralization to achieve regulated water quality standards. The Basin reactor system uses photosynthesis and rhizosphere dynamics to create a predictable reactor into carbon-rich microbial biomass to remove waste water pollutants (COC). The Basin uses <10% of the energy required for alternative tertiary treatment system. The Basin COC treatment functions year-round including through the trees dormant season.

A method for predicting operation effectiveness of a decentralized sewage treatment facility by using a support vector machine, comprising: simultaneously collecting an influent conductivity and an effluent conductivity, and recording operation effectiveness of the decentralized sewage treatment facility; training a training set by using the support vector machine, with the influent conductivity and effluent conductivity as input and the operation effectiveness of decentralized sewage treatment facilities as output, so as to construct a prediction model for the operation effectiveness of decentralized sewage treatment facilities; and collecting the influent conductivity and effluent conductivity of the treatment facilities to be predicted, and inputting them into the prediction model to obtain a predictive result. The method is not only highly accurate, but fast and inexpensive.

A method of using algae to remove a contaminant or pollutant from a first fluid is provided. The method can include providing a growing apparatus having a first reservoir containing the first fluid and a second reservoir containing a second fluid, and growing the algae using the growing apparatus. The method can further include exposing the algae to the first fluid within the first reservoir where the algae uptakes the contaminant or pollutant from the first fluid, and exposing the algae via a belt to the second fluid in the second reservoir where the algae is stimulated to release the contaminant or pollutant. Exposing the algae to the first fluid within the first reservoir or the second fluid may change a growth rate of the algae.

Methods of removing scale and inhibiting scale formation on a surface in an aqueous system are provided that include contacting a surface susceptible to scale formation or having a scale with a solution comprising an amount of a non-decomposed moss effective to remove some or all of the scale or inhibit scale formation on the surface. Methods of inhibiting corrosion on a surface in an aqueous system are provided that include contacting a surface susceptible to corrosion with a solution comprising an amount of a non-decomposed moss effective to inhibit corrosion on the surface.

The invention provides an integrated water treatment system suitable for use in the treatment of contaminated water, wastewater, potable water, aquaculture, industrial water and polluted water bodies. An integrated water treatment system according to at least one embodiment of the invention comprises a plurality of modules adapted to float in a body of water integrating a plurality of different attached growth biofilm media types positioned within a plurality of water flow paths and circulations. The conditions provided by a multiple of media types and plurality of flow paths creates a multiplier effect increasing the number of treatment zones and an increased diversity of interconnected treatment process zone types. Embodiments of the invention provide a diversity of conditions and biological habitats establishing a poly-culture of producers, consumers and higher organisms in an ecosystem of biological treatment processes, with complex metabolic pathways and food chains increasing treatment efficiency and the range of pollutants which may be effectively treated. Modules comprised in the system are adjustable in operational rate, series, and timing, and are movable in configuration and/or proximity providing a new type of adaptable, re-configurable and adjustable multi-zone, integrated ecological biofilm water treatment system.

Methods and systems for removing pollutants from water include one or more filter systems and a hybrid wetland system. Hybrid wetland systems may include a first pipe transporting water from a body of water to a settling tank, a first constructed wetland connected to the settling tank via a second pipe, and a first filter system removing pollutants from water passing through the second pipe. A second filter system is positioned within the first wetland to further remove pollutants. The system also includes a second constructed wetland connected to the first constructed wetland via a third pipe and a water control chamber. Filtered water exiting the first constructed wetland flows through the water control chamber, through the third pipe, and into the second constructed wetland. A fourth pipe extends between the second constructed wetland and the body of water, returning filtered water to the body of water.

Disclosed an aerobic system for decomposition of aqueous organic waste, which comprises at least a first processing container including sides, an upper opening, a substantially horizontal floor, an inlet, an outlet, at least one channel arranged at the floor having an upwardly opening mouth, a ventilating pipe extending above the mouth, and a pump connected to the pipe and arranged to provide a supply of a gas to the ventilating pipe.
