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 sensor 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.

An air treatment device and a control method are provided. The air treatment device includes a water tank assembly, a water trough and a sterilization device. The sterilization device includes a sterilization portion, the sterilization portion is provided in the water trough, a water replenishing switch is provided between the water tank assembly and the water trough, and the water replenishing switch is configured to control connection and disconnection between the water tank assembly and the water trough. The air treatment device further includes a control portion, and the control portion is capable of controlling an opening and closing of the sterilization portion according to an on-off state of the water replenishing switch to ensure a good sterilization effect.

A water purification device comprising a pre-purified water reservoir for storing pre-purified water, a water vapor chamber for receiving water vapor generated from heating the pre-purified water in the pre-purified water reservoir, a condensation chamber for receiving the water vapor and condensing the water vapor into purified water, and a Peltier device comprising a hot side and a cold side. The hot side of the Peltier device heats the pre-purified water into water vapor and the cold side of the Peltier device condenses the water vapor into purified water.

The present techniques are directed to a multiphase separation system. The system includes a liquid-liquid separator configured to receive a separated liquid that is further separated into a separated oil and a separated water within the liquid-liquid separator (126). An oil pump (136) and a water pump (138), both with adjustable speeds, are configured to pump the separated oil and the separated water, respectively, from the liquid-liquid separator (126). An interface level (140) in the liquid-liquid separator (126) is regulated by adjusting the speed of the oil pump (136) and the speed of the water pump (138).

A liquid level control system, which may be used with a clarifier in a sewage treatment plant, manages liquid level of an upstream basin by controlling liquid flow in or out of a system that may use a midstream device to equally distribute flow in or out of the basin. This headloss inducing device creates a non-linear relationship between upstream liquid level to be controlled and the lesser downstream liquid level behind the gate or valve. Without the use of electrical controls, the systems of the invention include a gate or valve with counterforces that manage the outflow stream of liquid while accounting for the non-linear head loss created by the midstream device, thus reaching a desired liquid level range for all system flowrates.

An electrolytic ion water generation method for generating strong electrolytic ion water having a pH value higher than a reference pH value through use of the same generation apparatus as an electrolytic ion water generation apparatus configured to generate electrolytic ion water having the reference pH value by setting an amount of raw water, which is to be supplied into a cathode chamber of an electrolytic bath, to be smaller than that of the raw water used for generating the electrolytic ion water having the reference pH value and setting generation conditions other than the amount of the raw water to the same generation conditions as those for generating the electrolytic ion water having the reference pH value. The raw water amount is set to a raw water amount calculated based on the following expression: pH=14+log [OH.sup.−].

An upflow continuous backwash deep bed sand filter (UCBF) having a recycle line for returning carbonaceous denitrifying bacteria attached to biomass to the influent of the UCBF. The recycle line returns the biomass to the treatment process at a location upstream of the upflow continuous backwash filter. Further, a liquid level control unit is provided that reduces fluctuations and significant drop in the liquid level upstream of the upflow continuous backwash filter, thereby avoiding or minimizing flow turbulences, air induction, and undesirable wastewater aeration resulting in the need to dose excessive carbon source to remove dissolved oxygen in the aerated wastewater.
