Abstract

A system and method for providing mobile or temporary water treatment involving ion exchange resins includes a service center, one or more treatment vehicles, a resin transfer hub and one or more resin transport vehicles. The service center can be used to regenerate one or more types of ion exchange resins. The treatment vehicle carries water treatment equipment including a tank holding ion exchange resin. The resin transfer hub facilitates moving resin between a treatment vehicle and a resin transport vehicle. The resin transport vehicle is adapted for carrying resin by one or more of land, sea and air between the resin forwarding center and the service center. In operation, a treatment vehicle brings resin requiring regeneration to the resin transfer hub, where it is emptied and then re-filled with regenerated resin. Resin requiring regeneration is transferred to a resin transport vehicle for transport to the service center. The resin transport vehicle is re-filled there with regenerated resin, which is taken back to the resin transfer hub for transferred to a treatment vehicle.

First claim

I claim:

1. A system for providing temporary or mobile water treatment using ion exchange resins comprising:
a service center adapted to regenerate one or more types of ion exchange resins;
a water treatment vehicle comprising a water treatment tank for containing a quantity spent ion exchange resin and an amount of water sufficient to fill the water treatment tank to a level above a level of the spent ion exchange resin and adapted to permit water being treated to flow through the resin;
first and second resin transport vehicles each having a storage tank for receiving ion exchange resin, wherein the storage tank of the first resin transport vehicle is for containing spent ion exchange resin and the storage tank of the second resin transport vehicle is for containing regenerated ion exchange resin;
a resin transfer hub having a compressed air system for moving spent ion exchange resin between the water treatment tank of the water treatment vehicle and the storage tank of the first resin transport vehicle using the compressed air system and for moving regenerated ion exchange resin between the storage tank of the second resin transport vehicle and the water treatment tank of the water treatment vehicle using the compressed air system; and
wherein the resin transfer hub is provided on or in a resin transfer hub vehicle that is separate from the first and second resin transport vehicles.

2. The system of claim 1 wherein the water treatment vehicle comprises a trailer adapted for transport by road.

3. The system of claim 1 wherein the first and second resin transport vehicles each comprises a tank mounted to a frame and the frame is adapted to be carried on the respective first and second resin transport vehicle.

4. The system of claim 3 wherein the first and second resin transport vehicles each comprises standardized mounting points that are positioned such that the resin transport vehicle may be transported through an ISO inter-modal transportation system.

5. The system of claim 3 wherein the first and second resin transport vehicles each further comprises an inlet near the top of the tank and an outlet near the bottom of the respective storage tank.

6. The system of claim 1 wherein the resin transfer hub vehicle is a shipping container.

7. The system of claim 1 further comprising a resin storage vessel connected to the resin transfer hub.

8. The system of claim 7 wherein the resin storage vessel comprises a silo.

9. The system of claim 1 further comprising a polishing unit having one or more tanks containing cation, anion and mixed resin beds, the resin tank connected to an inlet to the resin transfer hub.
