Method and apparatus for a low maintenance, high reliability on-site electrolytic generator incorporating automatic cell monitoring for contaminant film buildup, as well as automatically removing or cleaning the contaminant film. This method and apparatus preferably does not require human intervention to clean. For high current density cells, cleaning is preferably performed by reversing the polarity of the electrodes and applying a lower current density to the electrodes, preferably by adjusting the salinity or brine concentration of the electrolyte while keeping the voltage constant. Electrolyte flow preferably comprises water and brine flows which are preferably separately monitored and automatically adjusted. For bipolar cells, flow between modules arranged in parallel is preferably approximately equally distributed between modules and between intermediate electrodes within each module.

A vessel for treating an oil-in-water inlet stream houses an inlet flow distributor arranged to direct an inlet flow toward a perforated baffle of a coalescing section, the coalescing section housing a packing and being arranged upstream of a second baffle; a flotation section arranged to receive a flow exiting the coalescing section and being divided by one or more perforated baffles; and an outlet water collecting pipe arranged to receive a flow exiting the flotation section, the outlet water collecting pipe having one or more openings located along its length. The coalescing section may be divided into two sections, with one section preferably housing a different pre-selected sized packing than the other section. The flotation section may include one or more gas-inducing devices. A solid baffle may be arranged downstream of the second baffle and ahead of the flotation section to provide single or dual flow through that section.

A waste liquid treating apparatus for purifying a waste liquid discharged from a processing apparatus includes a waste liquid accommodating tank for the waste liquid discharged by the processing apparatus, a spray water seal type pump that sucks a spray together with air in a processing region where a processing unit is disposed, a sealing water reservoir tank that recovers the spray and reserves the spray as a waste liquid, and a waste liquid filter unit that filters that waste liquid and the waste liquid in the waste liquid accommodating tank, to purify the waste liquid into fresh water. A fresh water reservoir tank reserves the fresh water obtained by filtering the waste liquid, and a pure water producing unit purifies the fresh water reserved in the fresh water reservoir tank into pure water. A temperature control unit controls the temperature of the pure water.

Described herein is a method of identifying components in a fluid stream. Particularly, the invention relates to the identification and/or separation of one or more materials suspended in a fluid stream.

The subject of the invention is a device for the production of Redox water characterized by an increased amount of molecular hydrogen in its composition. A device for the production of Redox water of potential below −100 mV uses a spirally wound corrugated pipe, a water source, a water pump, a blow-off valve, a vent, and a gauge. The components are connected into one closed system. Water circulating in the closed system of the spirally wound corrugated pipe is kept under specific pressure. For the pipe, a ratio of diameters is in a fixed diameter range, and a ratio of distances between particular coils parallel to one another is within a distance range.
