A water cleaner, including a housing, a filtering mechanism and a filtering unit. Two ends of the housing are respectively provided with an inlet and an outlet. The filtering mechanism is arranged in the housing. The sewage flows into the housing through the inlet and flows towards the filtering mechanism. The filtering mechanism is configured to filter the sewage to obtain clean water, which flows out of the housing through the outlet. The filtering unit is arranged at the inlet of the housing, and is configured to allow water remaining in the housing to be discharged and prevent dirt remaining in the housing from being discharged when the water cleaner stops sewage purification and is separated from the sewage.

Provided are systems and methods for treating wastewater with a continuous-process mobile station. The mobile station may include one or more mobile units configured to receive a feed of wastewater. The one or more mobile units may include: a mobile ozonation unit configured to treat the received feed of wastewater with ozone gas to breakdown impurities in the wastewater, a pH control unit may be configured to raise pH of the treated wastewater, a mobile electrocoagulation unit configured to separate solids and metals from the treated wastewater, a mobile flocculation unit configured to cause suspended particles to form flocs and to remove the flocs from the received treated water.

A water desalinator that employs the use of solar concentration, evaporation and humidification, mimicking the natural hydrological cycle in a closed, modular vessel to produce freshwater from salt, brackish, brines and seawater, and a concentrate stream for further processing. Feed water is received and stored in a basin. Surface humidity is generated by the evaporation of basin water. A lens is used to focus sunlight, tracked the suns path based on biomimicry of a sunflower, on a thermal conductor. The thermal conductor has a rounded side-profile and generates a variable temperature across its radius. Water is pumped from the basin to a sprinkler head to be dripped or sprayed on the thermal conductor to generate water vapour. This water vapour consequently mixes with the air in the reaction vessel to increase system humidity. Humid air is removed from the reaction vessel and condensed in a condenser. Accordingly, the salinity concentration of input water is reduced from the output of the reaction vessel. Multiple reaction vessels or concentrators may be used in tandem to achieve improved performance.

Devices and methods are provided for in-line water treatment using strong magnetic fields to influence corrosion, separate toxins, suppress bacteria and bio-fouling, as well as inhibit or greatly reduce mineral scaling due to fluid flow in or around equipment components. For example, a device is provided for applying a magnetic field to a portion of tubing through which a fluid flow, such as water, is conveyed. The device includes a number of links joined together via detachable pivoting connections, such that links may be removed and/or links may be added, thereby allowing a diameter of the device to be adjusted so as to accommodate larger or smaller piping, as necessary, for retrofitting applications. The use of magnetic treatment of fluids such as water may allow extended cycles of operation with higher concentration of mineral salts without the use of chemical scaling suppressants.

A sludge treatment system, comprising a pump (1), an ozone generation device, an ejector (2) and pipe reactors (3). The pump (1), the ozone generation device, the ejector (2) and the pipe reactors (3) are sequentially connected by pipes. An oxygen generator (4) and an ozone machine (5) are arranged within the ozone generation device, and are connected by a pipe. The ozone generation device is used for providing ozone into the pipe reactors (3). The inner surfaces of the pipe reactors (3) are coated with a catalyst layer used for increasing the oxidative capacity of the ozone on the sludge. Spiral fin plates (6) allowing a fluid to generate a spiral flow are arranged within the pipe reactors (3). Also disclosed is a sludge treatment method using the present sludge treatment system. The present system has a high ozone utilization rate, and a low ozone input proportion.

A publicly accessible urban beach entertainment complex is disclosed, with a man-made tropical, pristine-clear lagoon as the centerpiece of the complex, with surrounding entertainment, educational, sports, and commercial facilities, the complex having controlled public access and providing the look and feel of a tropical beach with clear waters and sandy beaches. In addition a method for efficiently utilizing facilities and land that are vacant, underutilized, have limited uses, or that are contiguous to or nearby recreational, educational, sports, or commercial venues is disclosed. The method providing a publicly accessible urban beach entertainment complex with a centerpiece man-made tropical-style pristine-clear lagoon. The method allows for generating revenue and increasing efficiency by pairing vacant sites, underutilized sites, limited use land, or sites that are contiguous to entertainment, educational, sports, and/or commercial venues with urban beach entertainment complexes. The complex preferably has a controlled public access, thereby allowing entrance upon payment of a fee.

A process in which a waste stream containing microbes and organic constituents is passed through a process environment comprising a solid media, microbes, and higher animals, such that some of the microbes and/or organic constituents within the waste stream are removed from the waste stream and some of the removed microbes are destroyed or consumed by the higher animals. The process environment may include an irrigated environment, a submerged environment, or a combined environment.

The present invention relates to an apparatus for collecting and treating wastewater (1) based on biodegradation-recombination-biodegradation process, comprising: a shell (1.1), the space inside the shell is divided into a first chamber (1.2) and a second chamber (1.3) by a divider wall (1.4), wherein: the first chamber (1.2) contains biological medium suitable for heterotrophic microorganisms growth; the second chamber (1.3) contains biological medium suitable for autotrophic microorganisms and heterotrophic microorganisms growth. The present invention also relates to a system for collecting and treating wastewater combining rainwater drainage used for building, comprising: at least one wastewater treatment apparatus (1) above; a indoor pipe system for collecting and transferring wastewater, rainwater comprising a main vertical pipe (2), substantially horizontal branch pipes; and a outdoor pipe system for transferring wastewater combining rainwater drainage comprising a horizontal pipe (3) for connecting the indoor pipe system for collecting and transferring wastewater, rainwater to at least one wastewater treatment apparatus (1) above.

A modular filtration platform having at least one manifold head and at least one respective filter cartridge assembly. Each manifold head is connected to one another to establish a water flow in a series or parallel manner. Each filter cartridge assembly is releasably secured from rotation relative to the manifold head by a locking mechanism. An aperture on the filter cartridge assembly annular collar mates with a protruding resilient extension on either the manifold head or support bracket. Alternatively, an aperture on the filter cartridge assembly annular collar and an aperture on the manifold head annular collar mate with a protruding member from a locking ring extending through both apertures. An integrated sensor package may be integrated with the system for true managed water visible/audible indications and Wi-Fi interface to facilitate virtually instantaneous response times for filtration needs.

A method for controlling the growth of blue algae in a basin relates to the field of the restoration and protection of the natural ecology on the earth's surface. An ecological water treatment system was constructed for the basin with microorganisms, plants, animals, fillers and the like as main elements by building a novel ecological slope protection at the land-lake ecozone along the banks of the basin and planting eucalyptus in the basin water and/or on the bank of the basin, thereby effectively realizing the efficient nitrogen and phosphorus removal from the basin, controlling the spread of blue algae and improving the environmental water quality.
