A liquid filtering device that works in conjunction with an existing filtration system to provide, for example, cleaner water in a swimming pool.

The device includes a vessel to be filled with a mixture of water and a component producing foam, where the vessel comprises a device for blowing air into the mixture to produce foam. It is provided according to the disclosure that the device comprises at least two vessels to be filled with the mixture arranged one above the other in a vertical direction in tiers, where the vessels comprise the device for blowing air into the mixture to produce foam, where the vessels are open towards an outlet region such that the foam produced in the vessels is merged in the outlet region.

A wastewater management system includes a series of water treatment modules to treat wastewater and produce reusable and/or potable water and other beneficial byproducts of the wastewater treatment process. A pretreatment module, a filtration module, an evaporator module, an odor control module, a UV-light module, an autoclave module, a sonolysis module, an ozone module and a chlorination module are combined in multiple combinations along with holding tanks, condensers, flash tanks and other components to address water purification and reclamation needs based upon specific wastewater conditions. The system captures condensate from AC systems and rainwater from rainwater gutter systems processes the water to produce reusable and/or potable water with or without re-mineralization. Any CO.sub.2 produced by the water treatment system is captured and processed using naturally-occurring flora. The wastewater treatment system includes multiple closed-loop subsystems to minimize energy usage and maximize water purification and reclamation for reuse.

Provided is an ultrafine bubble generating apparatus that generates ultrafine bubbles by generating film boiling by causing a heater provided in a liquid to generate heat, the ultrafine bubble generating apparatus including: an element substrate including a first heater that generates the film boiling in the liquid and a second heater that is arranged adjacent to the first heater, in which the first heater and the second heater are driven in different timings.
