Abstract

A mobile water treatment system is disposed on a trailer of a truck. There is an intake filter, an intake hose, a pump or multiple pumps for water intake and sending water throughout the system, a filtering section that may include sand and/or bag filter or other types of filters, an ozone treatment section after the filters, a holding tank after the ozone section, a UV treatment section after the holding tank, and a chlorination tank. The water may then be sent to a water storage facility or other place as desired. The system includes a generator for power to run the system, and a controller for the system. The ozone section makes use of a misting nozzle in order to increase ozone contact time, and decrease ozone breakdown. The UV section makes use of a slightly downward tilted table with UV bulbs and reflectors above it, and preferably is mounted on a leveling system. A method of treating water uses the mobile system.

Claims

1. A water treatment system, comprising:

an input pump for pumping water from a source through the system;

a filter section receiving water from the input pump; and

a UV treatment section for applying UV light to the water,

wherein the UV treatment section comprises a tray for flow of water from an input end to an output end, and wherein UV lights are disposed above the surface of the water.

2. The water treatment system of claim 1, wherein there is an ozone treatment section between the filter section and the UV treatment section for applying ozone to the water.

3. The water treatment system of claim 1, wherein the input pump, filter section and UV treatment section are mounted on a trailer, and further comprising a generator mounted on the trailer. A portable water treatment system in which filters, pumps, and at least one of UV treatment and ozone treatment stations are disposed on a trailer.

4. The water treatment system of claim 2, wherein the ozone treatment section comprises a tank having nozzles for atomizing water, and a source of ozone, mixed with the ozone within the tank.

5. The water treatment system of claim 1, wherein reflectors are positioned at each UV light for reflecting UV light towards the water.

6. The water treatment system of claim 5, wherein the reflectors comprise a sheet comprising biaxially-oriented polyethylene terephthalate (boPET).

7. The water treatment system of claim 1, wherein the UV station is mounted on a leveling system comprising a fixed frame and a movable frame, the fixed frame having one actuator midway along one side thereof and fixed thereto, and another actuator midway along another side thereof and fixed thereto, and the actuators also being gimbaled at an upper end thereof to the movable frame, and bearings disposed along an intersection of axes of the gimbaled portion of the actuators to the movable frame and the bearings, the UV station being mounted on the movable frame.

8. The water treatment system of claim 7, wherein the leveling system includes a level detection mechanism comprising pendulums, each pendulum comprising a housing, a damping fluid therein, a pendulum arm for swinging freely within the housing, and detectors for detecting a position of a bottom portion of the pendulum.

12. The water treatment system of claim of claim 7, wherein the movable frame is supported on bearings located at a center of mass thereof, and the upper end of each linear actuator is positioned so as to align with an axis of a respective one of the bearings.

13. The water treatment system of claim 1, wherein the UV lights comprise elongated UV bulbs, and the UV tray further comprises multiple elongate baffles, wherein each of the baffles is perforated, and wherein each of the UV bulbs are disposed above and in line with each of the baffles, respectively.

14. The water treatment system of claim 1, wherein the UV tray further comprises a series of baffles which increase water residence time in the tray.

15. The water treatment system of claim 1, wherein the system comprises the ozone treatment section, and the ozone treatment section contains nozzles for atomizing the water for mixing with the ozone.

16. The water treatment system of claim 15, wherein each nozzle has means for swirling the water entering the nozzle.

17. The water treatment system of claim 15, wherein the ozone treatment section comprises a first tank, and the nozzles are contained within the tank, and there is a second tank located below the first tank for receiving ozone treated water to increase ozone water contact time.

18. The water treatment system of claim 1, wherein there is a UV treatment section, and the system further comprises a tank for receiving water treated by the UV treatment section, and means for chlorinating the water in the tank.

19. The water treatment system of claim 1, further comprising both the ozone treatment section and the UV treatment section, the UV treatment section being disposed downstream of the ozone treatment section.

20. The water treatment system of claim 19, wherein the system ozone treatment section includes an ozone monitor.

9. A method of treating water using a mobile treatment facility, wherein the method comprises the steps of:

mounting filters, pumps, hoses, and at least one of UV treatment and ozone treatment stations on a trailer;

driving the trailer to a source of water needing treatment;

a step of filtering water from the source; and

a step of treating the water with UV light.

10. The method of claim 9, wherein there is a step of flowing the water down a tray being relatively tilted, and applying UV light to the water which is flowing using UV bulbs and reflectors.

11. A water treatment station, comprising:

a UV treatment tray;

a leveling system on which the tray is mounted, a relative tilt of the tray being from a water input end to a water output end of the tray, whereby water will flow from the input end to the output end;

UV bulbs mounted above the tray extending substantially for a width of the tray and disposed along length of the tray; and

reflectors mounted around each UV bulb such that the reflectors cover substantially a length and width of the tray.
