摘要:
A system for treating wastewater including at least one water-treatment pathway having at least one wastewater inlet, at least one oxygen-permeable, water-impermeable wall, separating an interior of the pathway from outside air, and at least one treated wastewater outlet and arranged for at least aerobic treatment of the wastewater as it flows from the at least one wastewater inlet to the at least one treated wastewater outlet, at least one wastewater supply conduit, supplying the wastewater to the at least one wastewater inlet of the water-treatment pathway and at least one treated wastewater conduit, supplying treated wastewater from the at least one treated wastewater outlet of the at least one water-treatment pathway.
摘要:
A bacterial fuel cell including a plurality of anodes and a plurality of cathodes in liquid communication with a liquid to be purified, the plurality of anodes and the plurality of cathodes each including a metal electrical conductor arranged to be electrically coupled across a load in an electrical circuit and an electrically conductive coating at least between the metal electrical conductor and the liquid to be purified, the electrically conductive coating being operative to mutually seal the liquid and the electrical conductor from each other.

摘要:
A bacterial fuel cell including at least one anode and at least two cathodes in liquid communication with a liquid to be treated, the at least one anode being separated from the at least two cathodes by at least first and second electrically insulating spacers and the at least one anode and the at least two cathodes being electrically connected across an external load and the at least one anode and the at least two cathodes being wound together generally in a spiral configuration together with at least a third electrically insulating spacer.

摘要:
A method for removal of foam from at least one foam accumulation region in a wastewater treatment facility, the method including causing the foam to flow from the at least one foam accumulation region into at least one foam collector and removing the foam from the at least one foam collector.
摘要:
Provided is a system for dissolving gas into liquid contained within a body. The system may include a tubular body extending between a bottom end and a top end, a gas diffuser coupleable to a gas source and configured for discharging gas bubbles into the tubular body, and a liquid pump for propelling liquid within the tubular body in a downwards direction, against uprising gas bubbles, where the liquid egresses at the bottom end of the tubular body.
摘要:
A biomass carrier including a multiplicity of generally elongate plastic biomass attachment strips joined to each other at least one location therealong, the multiplicity of generally elongate plastic biomass attachment strips being mutually arranged to define a generally deformable biomass carrier including generally outer disposed biomass attachment strips and generally inner disposed biomass attachment strips. Apparatus and methods for manufacture of the biomass carrier as well as fluid treatment systems and methods using the biomass carrier are also disclosed.
摘要:
A method for treatment of nitrified wastewater, the method including supplying wastewater to be treated to a tank having a layer of biomass supporting media near or at the top thereof, retaining biomass on and below the biomass supporting media for a sufficient time such that the biomass hydrolyses and supplies organic carbon to the wastewater in the tank; denitrifying and simultaneously clarifying the wastewater by providing an upward flow of the wastewater in the tank through the layer of biomass supporting media and discharging excess sludge from the bottom of the tank at a rate which is selected to maintain nitrate and ammonia concentrations below selected thresholds.
