In a method for treatment of waste water, a module (5) is used which includes a number of carrier elements (7) arranged in a sandwich structure and configured to be perfused a flow of waste water. The module (5) further has a number of partitions (8) arranged between carrier elements (7) and configured to direct the flow of waste water through the module (5). The module (5) may also be used in a system together with an air supplying device (20) and a waste water vessel. The air is supplied to the module (5) by the air supplying device (20).

There is described a system for the treatment of a wastewater in a pond or lagoon containing a volume of water. The system comprises at least one enclosure comprising growth media and/or substrate therein for growing bacteria and/or biomass. The at least one enclosure is configured in the pond or lagoon to receive a volume of wastewater flowing therethrough from the pond or lagoon over a treatment period, and is configured to treat substantially the entire volume of water flowing through the pond or lagoon over time. A plurality of growth media and/or substrate can be provided in a given enclosure. Different enclosures may comprise different growth media and substrate therein.

A microbiological culture apparatus of a wastewater treatment system includes a cage, a spacing device received in the cage, and a plurality of culture woods vertically received in the cage and positioned by the spacing device. The spacing device restricts the culture woods in an upright status and spaces them from each other to form a passageway between each two of the neighboring culture woods. Wastewater flows through the passageways to have low temperature and high dissolved oxygen.

Water treatment structures may have at least a first geotextile fabric layer; a second geotextile fabric layer; a third geotextile fabric layer; a first filler layer with plastic particles, arranged between the first and second geotextile fabric layers; and a second filler layer with plastic particles, arranged between the second and third geotextile fabric layers, wherein the geotextile fabric layers and the filler layers are within a housing, and wherein the structure is configured such that contaminated water proceeds sequentially through the first geotextile fabric layer, the first filler layer, the second geotextile fabric layer, the second filler layer, and the third geotextile fabric layer. Methods of treating wastewater may involve passing wastewater, after optional oxygenating and pre-filtering, through such alternating layers of geotextile, preferably nonwoven, and polymer particles.

A wastewater treatment system includes an aeration tank under a plurality of trickling filters to receive wastewater from the trickling filters. A plurality of bacteria culture modules are received in each trickling filters. A plurality of blower devices and air pipes are provided to generate ventilation to cool the wastewater flowing out of the bacteria culture modules. Each of the bacteria culture modules has a cage in which a plurality of culture woods are vertically received. Therefore, a temperature of the wastewater is reduced to form an environment which is good to the bacteria.

Water treatment structures may have at least a first geotextile fabric layer; a second geotextile fabric layer; a third geotextile fabric layer; a first filler layer with plastic particles, arranged between the first and second geotextile fabric layers; and a second filler layer with plastic particles, arranged between the second and third geotextile fabric layers, wherein the geotextile fabric layers and the filler layers are within a housing, and wherein the structure is configured such that contaminated water proceeds sequentially through the first geotextile fabric layer, the first filler layer, the second geotextile fabric layer, the second filler layer, and the third geotextile fabric layer. Methods of treating wastewater may involve passing wastewater, after optional oxygenating and pre-filtering, through such alternating layers of geotextile, preferably nonwoven, and polymer particles.

The present disclosure provides methods and systems for processing or treating wastewater. The methods of systems of the present disclosure may perform a treatment process on a wastewater stream including gray water and black water to produce a product stream. The product stream may comprise a potable water stream or a stream of treated water with a reduced concentration of one or more contaminant originally included in the wastewater stream.

A wastewater treatment apparatus for remediation of a wastewater treatment system has a septic tank with a lower sludge layer and an upper liquid effluent layer. The apparatus is comprised of a brush that includes a brush arm having a first end, a second end, and bristles disposed on the brush arm between the first end and the second end. The brush is configured to be positioned within the liquid effluent layer in the septic tank in a vertical orientation such that the second end is disposed below the first end.

Provided is a nano-photocatalyst-microorganism composite multilayered light-transmitting combination support, comprising a plurality of wave-shaped plexiglass plates (1), a tandem rod holder (4), hollow elastic spacers (5), and fixing screws (6); each of the wave-shaped plexiglass plates (1) is provided with four fixing holes (7); the tandem rod holder (4) is provided with four tandem rods (8), and the four tandem rods (8) pass through the fixing holes (7); the tandem rods (8) between the two adjacent wave-shaped plexiglass plates (1) pass through the hollow elastic spacers (5); each of the tandem rods (8) is provided with a fixing screw (6) at the top end; each of the wave-shaped plexiglass plates (1) have different loading layers on the upper and lower surfaces, with a nano-photocatalyst-loading layer (2) on one surface and a degrading bacteria-loading layer (3) on the other surface. Also provided is a method of making the nano-photocatalyst-microorganism composite multilayered light-transmitting combination support.

A modular system for aeration and biosource augmentation of a body of water and a method of using the system to prevent or eliminate an algal bloom in a water body include one or more mechanical basins located outside the body of water and at least two of: one or more residence pods submerged in the body of water that aerate the body of water, dose beneficial biosource, host biosource, and provide biosource to the body of water; one or more residence air pods submerged in the body of water that aerate the body of water, host beneficial bacteria, and provide beneficial bacteria to the body of water; and one or more residence nano pods submerged in the body of water that host, the one or more residence pods or the one or more residence air pods in fluid communication with the one or more mechanical basins.
