Question: Is there any effect of high water pH in a laundry wash process? Our normal water supply pH is 7-8, but I recently encountered a pH of 9. What might cause this? Is it safe to increase sour to maintain a final linen pH of 6-7, or should I stick to the rule that final pH should be one less than the water supply pH?

Question: We have a problem with a clay-like substance in our drain lines and do not know what to do. It leaves a film on our reclaimer and is extremely difficult to clean. We have found main drains are covered with the substance as well. Any ideas?
Question: What is alkali hydrolysis? How can I test for it? Identify it? Prevent it? Resolve it? I know that washload titrations can identify alkali hydro. However, if our titration levels are normal. Can alkali hydrolysis still be affecting our merchandise? Our white tablecloths have become tender at the corners breaking apart (in one direction) and the breakdown of fibers is visible.
