Water Maintenance Case Study
Maintenance in most plants is more reactive in nature; it is done as the need arises. There is no deliberate action to perform preventative maintenance. The maintenance problems, like many other problems, are directly related to poor staffing and training. Operators were generally found to be ignorant of the consequences of poor maintenance, although some reported of poor support systems in place as the maintenance tasks were left for a single operator to manage. Don't drink the water. Many commercial airlines post this warning in their lavatories over the water faucet. What kind of filtration systems are necessary to ensure a high degree of water quality is maintained? What should we keep in mind when maintaining water filtration systems?

An UV filter relies on particulate filtration to remove contaminants prior to entering the UV chamber, ensuring the water is clear allowing full penetration of the UV radiation. So all the issues regarding maintenance of canister filters are just as critical in UV applications.
Regular maintenance of the UV filtration unit is also required. The life of the UV unit is approximately 1,000 gallons. It is recommending the operators change them out annually. This is because even though the lamp itself may be strong, if the water is particularly bad, or the canister filter doesn't get all of that, then it will get some clouding of the quartz sleeve that separates the lamp from the water. And if that gets cloudy, then the UV is not getting through."
Some of the UV filtration units that IWG manufactures have integrated monitoring systems to measure the efficiency of the lamp. In this case, regular inspection of the system during maintenance checks will ensure proper …show more content…
One simple means of transferring resin is through the use of education systems.
Extra technical information:
Storage and Handling of Ion Exchange Resins
Ion exchange resins are normally shipped in the water-swollen form and should be stored in a sheltered area and in a manner whereby the moisture within the beads is retained.
The resin may be stored in the plastic bag in which it was shipped, provided it is kept tightly sealed or transferred to a glass container.
Although freezing does no harm, repeated freezing and thawing should be avoided.
Backwash all resin beds to remove debris and suspended contaminants. Keep the resin in the exhausted rather than regenerated form. If necessary, convert the resin to the completely exhausted form, using dilute solutions of acid for the anion resin, caustic soda for strongly acidic resins.
