The disclosed invention is a fixed bed ion exchange water purification system. It employs a combination of electronically controlled process steps and specific systems configurations to duplicate the effects of moving resin beds from one operating position to another as is required in moving bed ion exchange water purification systems. The invention combines features of single fixed bed ion exchange systems with those of a moving bed system. The invention applies to the treatment of water having typical industrial and drinking water concentrations of various ions.

Methods and systems for removing perchiorate from water are disclosed which involve the use of a plurality of vessels containing an ion exchange resin having affinity for perchiorate ions, and in which perchiorate-contaminated water is passed over the resin in some but not all of the plurality of vessels operating in parallel to one another thereby removing perchlorate ion from the water stream and generating reduced perchlorate content product water streams and in which a subset of the plurality of vessels is removed from service, their resin is removed and replaced and they are returned to service.

A protective cover device is disclosed for use with a snowmobile having an engine compartment, windshield, handlebars, seat, track and skis. The protective cover is used for protecting the snowmobile from the elements during transportation thereof. The device includes a first portion for covering and protecting the engine compartment, windshield, handlebars and seat of the snowmobile. A second portion covers the track and skis. An arrangement is provided for removably sealing the first and second portions together such that when the first and second portions are sealed together, the first and second portions define therebetween an enclosure for the snowmobile. The arrangement is such that during transportation of the snowmobile, ingress of the elements such as H O, snow, slush and road contaminants onto the snowmobile is inhibited. The protective cover device enables the snowmobile to be completely protected and insulated from the elements that would otherwise tend to damage, corrode and reduce the usefulness of the snowmobile in the absence of the cover device.
