A multistage greywater treatment system including at least one separation stage, at least one solid removal stage, and at least one disinfection stage. The at least one separation stage is configured to separate water from one or more water draining device into at least three outputs including a first intermediate greywater. The at least one solid removal stage is configured to receive the first intermediate greywater and dissolve solids from the first intermediate greywater to output a second intermediate greywater. The at least one disinfection stage is configured to receive the second intermediate greywater. The resultant greywater may be provided to at least one recycled water consuming device after passing through the at least one separation stage, at least one solid removal stage, and the at least one disinfection stage.

A water disinfecting device has a housing, an inlet, an outlet, a high-power disinfecting light, at least one quartz pipe that carries water, and a reflective surface for increased dosage. By placing multiple quartz pipes side by side, the device can disinfect greater quantities of water, or provide for double exposure of water passing through the pipes. By using a powerful UV light and a reflective surface from the outside of a quartz pipe, the device is capable of disinfecting at a much higher success rate than other disinfecting devices found in the prior art while also allowing for ease of maintenance.

A system for sanitizing water in a hot tub is described. The system includes a sanitizing chamber, separate from the hot tub, and sized to hold a small portion of the water from the hot tub. A first conduit for conveys water from the hot tub to the sanitizing chamber. A second conduit conveys water from the sanitizing chamber to the hot tub. A pump is provided that moves water from the hot tub, through the first conduit into the sanitizing chamber and from the sanitizing chamber, through the second conduit, back into the hot tub. A heater heats the water in the sanitizing chamber to a temperature and for a time sufficient to destroy or deactivate undesirable microorganisms.

Given the complexity of architectural spaces and the need to calculate spherical irradiances, it is difficult to determine how much ultraviolet radiation is necessary to adequately kill airborne pathogens. An interior environment with luminaires is modeled. Spherical irradiance meters are positioned in the model and the direct and indirect spherical irradiance is calculated for each sensor. From this, an irradiance field is interpolated for a volume of interest, and using known fluence response values for killing pathogens, a reduction in the pathogens is predicted. Based on the predicted reduction, spaces are built accordingly, and ultraviolet luminaires are installed and controlled.

A system for meat processing may include: a conveyor configured to transport animal carcasses or portions of meat through a meat processing facility; and a spray system configured to spray each of the animal carcasses or portions of meat with aqueous ozone when each of the animal carcasses or portions of meat is transported to the spray system by the conveyor. The system may further include a second spray system configured to spray each of the animal carcasses or portions of meat with lactic acid or citric acid when each of the animal carcasses or portions of meat is transported to the second spray system by the conveyor.

One aspect of the invention relates to a composition comprising: water, soybean, molasses, a mineral mixture, an enzyme, and a microbial mixture comprising Bacillus subtilis 34KLB. Another aspect of the invention relates to a fermented composition of the above composition.

A device (20) for disinfecting a fluid, in particular water, has a reactor housing (15) with an inlet (19) for ingress and an outlet (9) for discharge of a fluid to be disinfected, wherein a reactor chamber (16) is formed in the reactor housing (15). The fluid to be disinfected flows through the reactor chamber (16) from the inlet (19) to the outlet (9) along a flow path (18). A UV irradiation device (21) with a plurality of UV LEDs (11) is provided, wherein the UV LEDs (11) are disposed on an elongated support element (7) and the support element (7) is configured to extend at least partially into the reactor housing (15) so that by means of the UV LEDs (11), UV light for disinfecting the fluid can irradiate the flow path in the reactor chamber. The support element (7) is releasably and exchangeably mounted in the reactor housing (15) and has a coolant passageway (5, 17) which extends through the support element (7) and through which a coolant can flow in order to cool the UV LEDs (11).

A system for treating and/or recycling gray water includes a first receiving tank for gray water, a second receiving tank for treated water and a fluidic treatment circuit between the first and second receiving tanks. The first receiving tank includes an element for oxygenating the water in the first receiving tank and a system adapted to deliver enzymes into the first receiving tank. The fluidic treatment circuit includes a filtration unit, a microfiltration unit including at least one microfilter, a disinfection unit and a membrane ultrafiltration unit.

One aspect of the present invention provides a method of treating ballast water, which includes: a first step of transporting a raw material from a first base to a second base where a vessel is configured to be anchored; a second step of inputting the raw material into an on-site treatment agent manufacturing facility located at the second base to manufacture a treatment agent; and a third step of supplying the treatment agent to the vessel anchored at the second base and treating ballast water using the treatment agent.

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.
