The present disclosure provides a resource-circulation-type and eco-friendly livestock manure treatment method, and a system for producing algal biomass used therein, the method being capable of: preventing water pollution while allowing livestock liquid fertilizer to be treated on the basis of a biological process; producing algal biomass; and supplying the produced algal biomass to livestock feed and farms.

An apparatus and method for consumption of at least one compound from a fluid are disclosed. A method, comprising: providing processed algae for subsequent use in accelerated consumption of at least one compound from a fluid to be treated by exposing algae to a processing fluid depleted in the at least one compound to be consumed by the algae in a processing vessel; adding said processed algae to a contact receptacle containing said fluid to be treated to reduce a concentration of said at least one compound from said fluid to be treated; and recirculating at least a portion of said algae and said processing fluid from said contact receptacle to said processing vessel. This makes the processed algae better adapted to reduce the amount or concentration of the at least one compound within the fluid more quickly than is possible with unprocessed algae.

The present invention relates to a method for treating wastewater. The method includes treating an influent flow of raw wastewater from one or more sources in a harvestable algae biofilm treatment system. The treated wastewater is then delivered to one or more wastewater treatment lagoons or a mechanized biological treatment system for additional treatment. Also disclosed is a system for treating wastewater.

According to present disclosure, there is disclosed an algae growth and cultivation system that provides a cost-efficient means of producing algae biomass as feedstock for algae-based products, such as, biofuel manufacture, and desirably impacts alternative/renewable energy production, nutrient recovery from waste streams, and valued byproducts production. The system as discussed herein is an integrated systems approach to wastewater treatment, algal strains selection for byproducts production, and recycle of algal-oil extraction waste or additional algae harvested as feedstock for fertilizer production. Embodiments of a system as discussed herein present an economically viable algae production system and process that allows algae-derived products such as biofuels, fertilizer, etc. to compete with petroleum products in the marketplace.

The present invention relates to a system or method for the remediation of wastewater with a treatment media in tandem with an electrocoagulation system. The system and method also include cleaning elements for cleaning distribution lines within the system and for cleaning the electrocoagulation system.

A water filtering system includes providing light deep into a liquid used in applications such as the cultivation of both attached and suspended photosynthetic organisms. The system is configured to inject a stream of bubbles into the liquid and a light source is configured to shines light through the bubbles. The bubbles allow some light to travel deep into the liquid along the length of the bubble stream and scatter/deflect some light out of the bubble stream and into the surrounding liquid including screens for growing algae.

The present application discloses a method of binding a metal ion in water. The method comprises contacting the water with a fraction of dissolved organic material (DOM) to form a complex between the DOM fraction and the metal ion; and optionally separating the complex from the water. The present application also discloses a use of DOM for binding a metal ion in water.

Carbon dioxide capture systems in accordance with various embodiments of the present disclosure are provided. In one embodiment, an apparatus for capturing carbon emissions from a vehicle is provided, comprising: an exhaust feeder comprising a first end and a second end, wherein the first end connects to the vehicle and receives exhaust gases emitted from the vehicle; a housing connected to the second end and secured to an exterior surface of the vehicle, wherein the housing receives the exhaust gases emitted from the vehicle via the exhaust feeder; wherein the housing comprises: at least one gas deflector surface that directs the exhaust gases to a sorbent material configured to capture carbon dioxide from the exhaust gases; a detachable section that allows for removal and installation of the sorbent material; and an exit port that allows for release of residual gases after the sorbent material captures carbon dioxide.

A water purification system comprises a bioreaction subsystem receiving contaminated input effluent and having a gas-lift anaerobic membrane bioreactor removing urea and organic matter to create a first effluent. A light-treatment subsystem receives the first effluent and exposes the first effluent to UV light to create a second effluent free from microorganisms. A reactor subsystem fluidically connects an ammonia-reducing reactor to the UV output and receives UV-treated second effluent and has a struvite regenerator connected to the ammonia-reducing reactor output, separating ammonia from the second effluent in the ammonia-reducing reactor, and outputting the ammonia. A separation subsystem fluidically connects to the reactor output and receives the second effluent substantially free from ammonia and has a continuous electro-deionization device separating brine/salts from the second effluent to produce potable water. A closed-loop includes an ammonia-converting subsystem and a sequential fertilizer producer.

A system that relates to the technical field of sewage purification includes microalgae culturing pond and constructed wetland that are connected in series. A microalgae capturing filler is arranged in the microalgae culturing pond, algae-containing water obtained from microalgae capturing filler is communicated with the constructed wetland for oxygen transfer and forming algal-bacterial mutualistic symbiosis for strengthened pollutant removal, and part of captured microalgae is introduced into an anoxic denitrification functional area away from a surface in constructed wetland by flow guide pipe. Microalgae culture and sewage purification are realized in microalgae culturing pond by taking sewage as a culture medium, 80% or more of the microalgae biomasses in microalgae culturing pond are recovered with low cost, part of microalgae is introduced into the anoxic denitrification functional area away from the surface in the constructed wetland, and lytic algae cells serving as a carbon source promote denitrification in the wetland.
