Disclosed are floating micro-aeration unit (FMU) devices, systems and methods for biological sulfide removal from water/wastewater bodies and streams. In some aspects, a system includes a manifold structure including one or more opening to flow air out of an interior of the manifold structure; one or more support structures connected to the manifold structure, in which the one or more support structures are floatable on a surface of a fluid that includes water or a wastewater; and an air source that flows air to the manifold structure, such that the manifold structure supplies the air containing a predetermined amount of oxygen (e.g., less than 0.1 mg/L of oxygen) to oxidize sulfide of the fluid.

Scalable floating micro-aeration unit, devices and methods

Disclosed are anode electrode structures for microbial fuel cell (MFC) devices, systems and methods for treating wastewater and generating electrical energy through a bioelectrochemical waste-to-energy conversion process. In some aspects, an anode electrode includes a conductive core and a plurality of sheets of conductive textile material wound around the conductive core. In some aspects, the anode electrode is produced by cutting sheets of a conductive textile material to form a stem and a plurality of branches connected to the stem. The conductive textile material is pretreated to enhance the surface area, hydrophilicity, microbial attachment, and/or electrochemical activity of the conductive textile material. The sheets are stacked together and wound around a conductive core to produce the anode electrode. In implementations, the anode electrode can be used to transfer electrons removed from wastewater surrounding the branched electrode via an oxidation reaction on the electrode surface within the an MFC device.

Branched anodes for microbial fuel cells

Disclosed are devices, systems and methods for operation and control of gravity-fed fluid flows in water and wastewater related systems. The disclosed flow control system uses gravity to provide a flow of a fluid from a fluid source and a motorized flow control device fluidically coupled to the fluid source to control a defined flow rate of the flow by changing a position of an internal volume of the flow control device through which the fluid flows relative to a fixed level of the fluid in the fluid source. The disclosed devices, systems and methods can be used in a wide variety of systems for environmental and low-energy demand applications such as, for example, a wastewater treatment system to control a flow of wastewater in the system.

Fluid flow control for water treatment systems

Disclosed are modular microbial fuel cell (MFC) devices, systems and methods for treating wastewater and generating electrical energy through a bioelectrochemical waste-to-energy conversion process. In some aspects, a modular MFC system includes a wastewater pretreatment system to receive and pre-treat raw wastewater for feeding pre-treated wastewater for bioelectrochemical processing; one or more modular MFC devices to bioelectrochemically process the pre-treated wastewater by concurrently generating electrical energy and digesting organic contaminants and particulates in the wastewater to yield treated, cleaner water; and a water collection module to receive the treated water from the one or more modular MFC devices and store the treated water and/or route the treated water from the system.
