A sensor control system of a food processing system includes a logic processor operatively coupled to an electrode. The logic processor is configured to receive a sensor signal from the electrode, the electrode configured to collect the sensor signal from water used within the food processing system, process the sensor signal to determine a chemical measurement of the water, and generate an electrochemical cleaning control signal for the electrode to interact with the water to electrochemically clean the electrode based upon a user input signal.

Provided are nanonets comprising a) a surfactant aggregate having an average aggregate diameter; and b) a polymer having an average particle diameter which average particle diameter is the same or smaller than the average aggregate diameter, wherein the nanonet has a diameter larger than the average particle diameter. Also provided are kits therefor and methods for sequestering non-water moieties from aqueous solutions using nanonets.

A method for treating an aqueous fluid containing a biodegradable organic substance in an installation that includes an upflow bioreactor containing a sludge bed, wherein the sludge bed includes biomass, an external separator, and a conditioning tank. The method includes treating the fluid in the conditioning tank; feeding the treated fluid into a lower part of the bioreactor and forming biogas; withdrawing the fluid from an upper part of the bioreactor, which withdrawn fluid includes biomass; feeding the aqueous fluid withdrawn from the upper part of the bioreactor into the external separator, wherein the aqueous fluid that includes the biomass is separated into a liquid phase and a fluid phase enriched in biomass; returning the fluid phase enriched in biomass from the external separator to the bioreactor; and returning a part of the liquid phase to the conditioning tank.

A wastewater treatment system includes a reservoir, a parameter-adjusting subsystem, and a release mechanism. The reservoir is configured to receive waste liquid from a production system and to hold liquid under treatment including the waste liquid. The parameter-adjusting subsystem is configured to measure a parameter of the liquid under treatment and to treat the liquid under treatment to adjust the parameter. The release mechanism is configured to release the liquid under treatment from the reservoir under control of the parameter-adjusting subsystem. A process of treating waste liquid includes receiving waste liquid from a production system into a reservoir, holding liquid under treatment including the received waste liquid in the reservoir, measuring a parameter of the liquid under treatment, treating the liquid under treatment to adjust the measured parameter, and releasing the liquid under treatment from the reservoir after treating the liquid under treatment.

In described embodiments, a method of processing sludge of a poultry plant into solids includes storing sludge in a tank where the sludge is a dissolved air floatation (DAF) float treated with Polymer Chemistry. A polymer is added to the sludge to produce a slurry that is separated into at least one liquid phase and solids in a horizontal decanter centrifuge having a weir ring. In conjunction with operating the centrifuge with a laminar flow, adjusted feed rate and polymer dosing, the system allows for production of low moisture solids (<50%) from the poultry plant DAF float and discharge of a clear liquid phase.

A system for recovering fat, oil and grease (FOG) from wastewater has multiple annular flotation zones in a concentric configuration surrounding a central column to create progressively increasing surface areas for FOG and solid particles flotation, and thereby enhance FOG recovery and removal. Each flotation zone is equipped with an independent pressurized micro air and ozone bubbles distribution system. A controlled amount of ozone can be injected into the wastewater along with recirculated effluent and micro-size air bubbles. Upon the release of pressurized air-ozone-water mixture, micro-size bubbles are generated and distributed in each flotation zone to effectively float up FOG and solid particles in the wastewater stream.

Provided are sequestering agents for sequestering non-water moieties from an aqueous solution. The sequestering agents may comprise a detergent; and a polymer operable to stabilize formation of a detergent micelle thereby causing the detergent and polymer to self-assemble into a nanonet upon exposure to the aqueous solution. Also provided are kits therefore and methods for use of the sequestering agents and kits.

A method, a system and an apparatus for wastewater treatment using a combination of separation of fat, oil and grease (FOG) and biological treatment for reducing the amount of fat, oil and grease (FOG) in wastewater with the aid of a liquid culture of microorganisms is provided. In particular, the technology disclosed relates to a method and process for the separation and treatment of FOG, as well as a container tank and an outlet pipe construction adapted for improving the gravimetric FOG separation process and the breaking down of FOG using microorganisms.

The invention relates to a generator and its operation and use for generating toroidal and spatial vortices in a liquid. It comprises a rotationally symmetrical stator housing with an inlet opening and an eccentric outlet opening. It further comprises a rotor rotatably arranged in the stator housing with radially outwardly extending channels in constant fluid connection to the inlet opening. The rotor comprises a rotor disc, radially outside of the rotor with a side surface with inner notches in fluid connection to the rotor channels. The stator housing comprises a stator disc comprising a side surface with stator notches. When these notches face each other due to rotation of the rotor disc, a periodical liquid flow from the inner notches to the stator notches is formed and toroidal vortices are generated in the portioned liquid by shear stress as the portions of liquid move back and forth in the notches.

The disclosure provides a compact and high-rate bioreactor for wastewater treatment comprising a feeding port for introducing a feed of waste material, a reaction zone in liquid communication with the feed port when the bioreactor is in operation and having an aerator to provide an airlift configuration in the reaction zone; a settling zone comprising a separator for separating a liquid effluent from solid particles; a liquid effluent outlet port for withdrawing the liquid effluent; and a solids outlet port for removing solids. Further provided is a spiral separator for use in a bioreactor and a system comprising the bioreactor and a membrane separator to provide hygienic water.
