FINALLY, IT’S SUMMER! – ISSUE NO. 524

Summer is finally here! The weather is getting warmer, and everyone is getting ready to head to the beach or take a dip in the pool after the rainy cool Spring. Every Summer, parks are also in the news - emphasizing the importance of monitoring water quality to ensure that beaches are safe for swimming.

Water quality is critical with most uses. During medical device reprocessing, it's important to test the water quality because it is key to the performance of chemical cleaning agents. In particular, hard water binds up detergent molecules, preventing them from breaking down the contaminants. Further, these molecules are often a source of staining and pitting of devices. Enzymes used in enzymatic detergent are highly influenced by the pH level of water. An improper pH level can lead to the partial or complete inactivation of the enzymes relied upon to breakdown the soil on instruments. Total alkalinity measures the amount of alkaline buffers in water. These alkaline substances buffer the water against sudden changes in pH. Total alkalinity is the key to maintaining water balance.

Be sure your department has regular testing in place to be sure you are cleaning with the optimal water quality.
