The present invention relates to systems and methods for cleaning materials, such as flooring and upholstery. In some cases, the systems and methods use an electrolytic cell to electrolyze a solution comprising sodium carbonate, sodium bicarbonate, sodium acetate, sodium percarbonate, potassium carbonate, potassium bicarbonate, and/or any other suitable chemical to generate electrolyzed alkaline water and/or electrolyzed oxidizing water. In some cases, the cell comprises a recirculation loop that recirculates anolyte through an anode compartment of the cell. In some cases, the cell further comprises a senor and a processor, where the processor is configured to automatically change an operation of the cell, based on a reading from the sensor. In some cases, a fluid flows past a magnet before entering the cell. In some additional cases, fluid from the cell is conditioned by being split into multiple conduits that run in proximity to each other. Additional implementations are described.

A fluid filter device and method of using the same are disclosed. The filter device may include a casing including a first face, a second face and at least one lateral face positioned between the first face and the second face and perpendicular thereto. The filter device may include at least two elongated pulleys rotatably supported within the casing between the first face and the second face of the casing. The filter device may include a filtering mesh threaded on at least some of the elongated pulleys to define an interior of the filtering mesh. The elongated pulleys and locations thereof within the casing are adapted to arrange the filtering mesh into a predetermined shape and to enable rotation of the filtering mesh about the at least some of the elongated pulleys.

Methods of treating wastewater with a sequencing batch reactor are disclosed. The methods include determining an anticipated flow rate of the wastewater and independently operating one or more reactor in a continuous flow mode responsive to the anticipated flow rate. Sequencing batch reactor systems are also disclosed. The systems include a plurality of reactors operating in parallel, a loading subsystem, a measuring subsystem, and a controller. The controller can be configured to independently operate each of the reactors in a batch flow mode or in a continuous flow mode responsive to the anticipated flow rate. Methods of retrofitting existing sequencing batch reactor systems and methods of facilitating treatment of wastewater with sequencing batch reactor systems are also disclosed.

A device for monitoring the level or amount of a material within a container is provided. The device includes a detection mechanism that can be a direct detection mechanism or an indirect detection mechanism. When the detection mechanism senses an upper level of the substance in the container that is below a predetermined lower limit for the substance, the mechanism operates an alarm mechanism to emit an alarm to alert an individual to the low level of the substance within the container. The alarm can wirelessly communicate a salt level state to a wireless network or a device on a wireless network that can transmit the status through the Internet to any remote location. In one aspect, the alarm can be sent on a mesh network with a device that can transmit the status and other conditions through the Internet and to an application executing on a mobile device.

A method for predicting a dissolved oxygen level in treated seawater includes directing raw seawater from a fluid channel into a deaerator, directing an inert gas and an oxygen scavenger solution into the deaerator, thereby removing dissolved oxygen from the raw seawater such that treated seawater exits the deaerator, receiving information about a plurality of input parameters comprising a raw seawater flow rate, an inert gas flow rate, and an oxygen scavenger flow rate, implementing a neural network trained to predict the dissolved oxygen level of the treated seawater based on the plurality of input parameters and predicting, with the neural network, the dissolved oxygen level of the treated seawater based on the plurality of input parameters.

A device for selectively removing a perfluorinated compound may include an adsorption electrooxidation tank including a reaction unit having a plurality of electrodes and granular activated carbon configured to oxidize and decompose a perfluorinated compound in raw water through adsorption and electrooxidation, a power supply device configured to supply power to the adsorption electrooxidation tank, and a head adjustment pipe unit configured to maintain a water level within the reaction unit at a height greater than or equal to a reaction height of the electrode.

A hydro turbulator system includes a volute that has a top duct and a bottom duct that allow fluid to enter and exit the volute. An impeller system including a first impeller and a second impeller is positioned within the volute. The first impeller and the second impeller are axially aligned. A motor is operationally connected to the impeller system so that the first impeller and the second impeller rotate upon operation of the motor. Rotation of the first impeller and the second impeller creates successive zones of high pressure and low pressure to agitate and condition fluid within the volute.

An indirect evaporative cooling system for cooling a space adjacent to or containing an ablution bay is described. The indirect evaporative cooling system includes a greywater source from the ablution bay and evaporative cooler apparatus located above the space to be cooled in a dome shaped housing. The evaporative cooler apparatus includes a wet channel, at least one spray nozzle, and a dry channel. The at least one spray nozzle is located at the top of the evaporative cooler apparatus and is fluidly connected to the greywater source and the wet channel. The wet channel is located directly above the dry channel. A first side of the dry channel is connected to a first opening with a fan and outside air.

According to one embodiment, a method for removing antimicrobial material from a composition includes providing a container that contains a plurality of carbon elements such as granules, rocks and sheets. The carbon elements are submerged with a liquid and a composition that includes an antimicrobial material is deposited in the container. The carbon elements are configured to remove the antimicrobial material from the composition. The level of the liquid in the container is monitored and controlled to maintain a submerged condition of the carbon elements.

A system and process for decontaminating a bio-contaminated wastewater fluid as from a slaughterhouse or similar facility. The system and process recovers purified vapor/steam through a decontamination unit having a plurality of alternating rotating trays and fixed baffles in a processing vessel producing separate purified and contaminant streams. One or more filter/strainer units are disposed in parallel before the decontamination unit, and may be used alternately while the other is cleaned. A rotating shaft connected to the rotating trays may also connected to an electrical generator to provide electricity for circuits and controls in the system.
