Stormwater biofiltration system and method
11124959 · 2021-09-21 · ·

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.

Horizontal flow biofilter system and method of use thereof

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.

REMOVAL AND INHIBITION OF SCALE AND INHIBITION OF CORROSION BY USE OF MOSS
20210214253 · 2021-07-15 ·

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.

Treatment of oil and grease in water using algae
11066316 · 2021-07-20 · ·

A method for treating an oil-containing medium including oil or grease or both oil and grease includes the steps of combining algae with an oil-containing medium and allowing the algae to engulf or uptake at least a portion of the oil or grease in the oil-containing medium. A mixture for treating oil or grease or both oil and grease includes an oil-containing medium including oil or grease or both oil and grease and phagotrophic algae that engulf or uptake at least a portion of the oil or grease in the oil-containing medium.

MICROALGAE CULTURES USING SEALED VERTICAL PHOTOBIOREACTORS
20210230524 · 2021-07-29 ·

A microalgae culture broth producing system includes a device for culture broth sterilization using a micro bubble generator, an air compression and pressure equalization device for the injection of carbon dioxide and oxygen in the atmosphere into the culture broth. The system also includes an air chilling device to maintain suitable culture broth temperature when water temperature is too high, an automatic carbon dioxide supply device to promote photosynthesis, and a sealed vertical photobioreactor to block out pollutants and increase dissolved carbon dioxide and oxygen concentration. The system further includes a high-efficiency harvesting device using hollow fiber membranes, and a hot air drying device using the waste heat generated by air compression.

<i>Lysinibacillus fusiformis </i>with methylamine degradability and application thereof

The present invention discloses a strain of Lysinibacillus fusiformis with methylamine degradability and the application thereof. This strain, named Lysinibacillus fusiformis GDUTAN2, was deposited on May 24, 2017 in the China Center for Type Culture Collection in Wuhan University, Wuhan City, Hubei Province with a deposit number of CCTCC NO. M 2017284. This Lysinibacillus fusiformis GDUTAN2 was Grain-positive and rod-shaped, and the colony appeared to be round, white and transparent, having a diameter of 1-2 mm. The Lysinibacillus fusiformis GDUTAN2 of the present invention can be applied to environmental restoration, degrading methylamine in the environment at a high degradation efficiency. When it degraded methylamine for 96 h at a substrate concentration of 130 mg/L, the degradation efficiency could reach 32.8%.
