A system (20, 70) for water treatment includes a plurality of containers (22, 24, 26, 80) which are configured to be stacked one on another for shipment and to deployed in a row at different, respective heights at a water treatment site. Each container includes an inlet (37, 86) at a first side of the container and an outlet (88) at a second side of the container, opposite the first side. The containers are filled with substrates (36, 38, 40) configured for planting of aquatic plants (60) therein and including at least different first and second substrates for filling the first and second containers, respectively. Piping includes at least an inlet pipe (34) for connection to the inlet of a first container, a transfer pipe (64, 66) for connection between the outlet of the first container and the inlet of a second container, and an outlet pipe (41) for connection to the outlet of the second container.

The present invention provides a method of stopping larvae of sessile invertebrates in the settlement stage from swimming or crawling in water, by irradiating light comprising the spectrum of 409 to 412 nm and a part of 400 to 440 nm, to the larvae in the settlement stage.

The present invention provides a method of killing larvae of sessile invertebrates in the settlement stage in water, comprising the step of irradiating light comprising the spectrum of 409 to 412 nm, to the larvae in the settlement stage.

A stormwater treatment system and method for removing sediment, chemical pollutants, and debris from stormwater runoff by utilizing bioretention practices including physical, chemical and biological processes. Stormwater is directed into a primarily open-bottomed, multi-dimensional container whereby entrained sediment and other transportable materials are filtered and treated through a media filter layer consisting of inorganic and/or organic materials. A live plant (preferably a tree) situated within the container with roots resident in the media filter layer with the ability for expansion beyond the perimeter of the container through openings in one or more sidewalls. The treated water may be further conveyed beyond the perimeter of the container by additional openings and/or piping. A vertically positioned overflow/bypass/clean out piping apparatus may be included within the stormwater treatment system to provide additional water conveyance. Additional ancillary conveyance, filtration and storage facilities may be connected to the described stormwater treatment system as conditions warrant.

A water treatment system for a recirculation aquaculture facility, related method and uses thereof are provided. The water treatment system included a water pre-treatment facility and a groundwater recharge arrangement, wherein the water treatment system forms a primary recirculation flow pathway when integrated with the recirculation aquaculture facility, thereupon effluent discharged from the recirculation aquaculture facility is sequentially directed through and back into the recirculation aquaculture facility via a water collecting circuit network to enter the recirculation aquaculture facility as an influent. The secondary recirculation flow pathway is formed internally within the recirculation aquaculture facility.

A horizontal flow water treatment method and wetland biofilter apparatus provides 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 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.

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.

A method for removing ectoparasites, such as sea lice, from a fish in water, comprising: (i) administering a neonicotinoid to remove the ectoparasites from the fish; and (ii) exchanging the water comprising the removed ectoparasites with replacement water, thereby separating the removed ectoparasites and the fish. The neonicotinoid is not imidacloprid, and is not configured or formulated for in-feed administration. The fish may be a salmonid, char, or cleaner fish, and the neonicotinoid may be applied at a sublethal dose and/or for a sublethal time, at a lethal dose and/or for a lethal time, or at a dose that knocks down the ectoparasites. The method may further comprise the step of preventing release of the removed ectoparasites into the environment, for example by collecting the ectoparasites from a sample of water comprising the removed ectoparasites, for example by passing the sample through a filter, preferably a mesh filter. A neonicotinoid for use in the method is also provided.

A liquid treatment system is provided having a vault that contains a treatment chamber and an outflow chamber. The treatment chamber may have a filtration media layer containing media that treats liquid as it descends through the filtration media layer, where it will accumulate in a porous layer or open space. The liquid will then be directed through the plurality of pipes to the outflow chamber, where the treated liquid is further directed to outside the system. Accumulated debris settled at the bottom of the treatment chamber may be flushed out by a spray bar.

Provided herein are lagoon systems and methods for industrial wastewater remediation.
