A system for storing biological feedstock includes receiving tanks, storage tanks, and at least one slop tank. The biological feedstock is supplied to the receiving tanks from sources external to the system. Fat separated from the biological feedstock is transferred from the receiving tanks to the storage tanks, and sludge deposited on a bottom portion of each receiving tank and on a bottom portion of each storage tank is transferred to the slop tank. Fat separated from the sludge is transferred from the slop tank to the receiving tanks. Biological material is blended from biological feedstocks. The tanks act in different roles to improve the removal of sludge, and increases the yield of desired biological material.

A method for preventing and treating pollution plume migration of a permeable reactive barrier including: mounting monitoring assemblies, so as to monitor operation parameters of an active filler in a reactive barrier and a downstream water body of the reactive barrier in real time; determining whether the active filler in the reactive barrier is passivated according to a change state of the operation parameters, and if passivation occurs, performing a depassivation treatment on the reactive barrier; determining whether a gas blockage occurs in the active filler in the reactive barrier according to the change state of the operation parameters, and if a gas blockage occurs, performing a gas guiding treatment on the reactive barrier; and determining whether a microorganism content in the reactive barrier is greater than a preset microorganism value according to the change state of the operation parameters.

Apparatus 101 for producing a continuous stream of biohydrogen includes a continuous flow stirred tank reactor (CSTR) 12, lighting arrangement 13; ports 14; peristaltic pumps 16; and gas chromatograph (GC) 18. The CSTR 12 includes internal bioreactor chamber 20; a photosynthesizing microorganism inlet stream 22.1 for delivering Chlorella vulgaris; an organic waste inlet stream 22.2 for delivering wastewater activated sludge (WWAS); and a nutrient inlet stream 22.3 for delivering nutrients into the chamber 20; an outlet stream 24; and stirrers for stirring the contents of the chamber. The lighting 13 is provided by lamps 26 for transmitting light through a transparent sidewall of the chamber 20. The ports 14 and CG 18 are for taking measurements from the chamber 20. The pumps 16 control flowrate of the streams 22.1, 22.2, 22.3 and 24 for regulating biohydrogen production from fermentation while Chlorella vulgaris consumes oxygen to avoid biohydrogen conversion into methane.

The disclosure relates to methods, systems, and apparatus configured to manage a filtration media bed and apparatuses associated therewith. Information associated with the detection of an amount of one or more target contaminates present in a gas phase or liquid phase in a filtration operation can be provided. One or more target contaminates can be removed from a gas or liquid phase traveling in and through the system via a media bed material. The filtration system media bed arrangement can include a plurality of media bed zones. Sensors or sensor arrangements can detect an amount of target contaminate that has flowed through the filtration apparatus over a period of time vis a vis one or more media bed zones. Condition states for each of the media bed zones or the entirety of a media bed arrangement can be generated to better ensure effective target contaminant removal over time.

A water treatment device includes an oxidizing substance removal device removing oxidizing substances from water to be treated. The oxidizing substance removal device includes: a hydrogen adder adding hydrogen to the water to be treated; a catalyst tower with a platinum group metal-supported catalyst through which the water to be treated to which hydrogen has been added passes; a control unit that controls an additive amount of hydrogen; and a first meter measuring the dissolved hydrogen concentration in the outlet water of the catalyst tower. A layer height of a packed material in the catalyst tower, including the platinum group metal-supported catalyst, is 10 cm or more, and the control unit performs a first additive amount control that controls the additive amount of hydrogen so that a measured value by the first meter is within a first range.

Illustrative configurations of a pet hydration system and methods are disclosed. The pet hydration system includes a bowl section configured to temporarily store water therein. In one configuration, a hydrogen-generation assembly is positioned in the bowl section. The hydrogen-generation assembly generates and introduces hydrogen into the water temporarily stored in the bowl section. In other configurations, methods related to pet hydration are also disclosed.

A conveyable medium, which may be gaseous, liquid, viscous, pasty, or pulverulent, is dispensed into an organism (human, animal, plant) or onto a technical system in a targeted, controlled, closed-loop controlled, and monitored manner by a displacement pumping principle using a gas produced by a gas generating cell. Conveyable media may be medicaments or active ingredients in a liquid, dissolved, or viscous form, as well as any type of supporting substance and liquid, and lubricants or protective agents (grease, oil) or reagents. The system includes the following parts: a) an operating, control, regulating, monitoring, and communication unit; b) a gas drive unit; c) an active ingredient reservoir; and d) a connection system.
