Water Purification System Preventative Maintenance

Water purification systems work to eliminate contaminants from tap water and make it safe to drink, cook and wash. These systems require routine maintenance to keep them running at peak performance and avoid expensive repairs. Using a preventative maintenance checklist is a good way to ensure they continue to function properly.

Annual Inspections

Whether you use reverse osmosis (RO) treatment, ultraviolet light treatment or water softeners, water purification systems require maintenance to operate properly and ensure that your water is safe for consumption. Performing routine preventative maintenance can extend the life of a system, minimize production interruptions and avoid expensive repairs. Annual inspections are a key part of a water purification system’s preventative maintenance program. Technicians can perform a number of services during an inspection to keep your system functioning smoothly and safely. A water purification system’s membranes and filters need to be cleaned regularly based on their average lifespan. Technicians can also replace worn-out parts to maintain proper operation. They can also check the system’s electronic controllers for damage and calibrate them when needed.

Filter Changes

Filter changes are one of the most common preventative maintenance tasks for water filtration systems, and they can have a big impact on the life of your system. Performing filter replacements at the recommended interval can help your system last longer, avoid expensive repairs and ensure that it is working properly. Manufacturers recommend that filter changes should be performed when the filters have been idle for longer than a week or so. This is because water that has sat within the filter media will likely start to cause microbiological growth, and your system needs to be flushed to displace these microbes before it can be used again.

Pressure Tests

Pressure tests are a critical part of water purification system preventative maintenance. They ensure that the equipment and piping system are functioning properly and are up to industry standards. They also help organizations avoid expensive repairs and ensure the quality of the water that their systems produce is up to safety and health standards. They can be performed either hydrostatically or pneumatically. Pneumatic testing is usually done in confined spaces where it’s easier to detect leaks. However, it needs to be conducted using special precautions and be overseen by senior staff members. The fluid normally used for pneumatic testing is compressed air, although nitrogen can be used as long as it is not sourced from bottled gas. It should be purged prior to use in a confined space if it can displace the air in the area. This is a non-destructive leak test method that requires the piping system to be filled with the fluid and pressurized. The pressure loss during the test is recorded and analyzed to determine if there is a leak.

UV Light Tests

UV light disinfection is an effective way to sanitize your water supply, but it requires proper maintenance and regular lamp replacement. Depending on the manufacturer of your system, it should have specific instructions and procedures for keeping it operating at its best. Using UV light to treat your drinking water can help keep your employees, guests and customers healthy. UV radiation strikes the cells of microorganisms, destroying their DNA and preventing them from replicating. The effectiveness of UV disinfection varies according to a number of factors, including the water’s physical characteristics and dissolved organic matter (DOM). These substances absorb or shield UV rays, which results in lower delivered doses and reduced microbial disinfection. To keep your UV system working at its optimal level, you should perform regular cleaning of the quartz sleeve that protects the UV lamp. This will remove mineral and sediment build-up that can inhibit the UV rays from penetrating the water. Also, you should change the UV lamp yearly to maintain its effectiveness.
