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.

An oil-contaminated soil and groundwater treatment system, in which the polluted groundwater pumped into the electrocatalytic device uses a high-voltage electric field to change the structure of water molecules. After high voltage discharge, electrocatalysis and electrolysis, alkaline reduced water, acidic oxidized water and neutral water can be quickly produced. By the oxidation effect of electrocatalytic device anode, chloride ions and dissolved oxygen in water generate hypochlorous acid and superoxide ions, and the interaction between the two generates hydroxyl radicals and microbubbles with high oxidizing ability and long-lasting oxidation, thereby effectively remediating soil and groundwater polluted by total petroleum hydrocarbons.
