Q. We are a waste treatment plant with an in-house ultrafiltration system. We keep experiencing rapid biofouling of our filters causing an excessive need to take the system out of service for cleaning. We suspect that microbes are growing inside the system and rapidly clogging the pores of the filter. We have tried hot NaOH flushes and we see little to no improvement on the … [Read more...] about Remove Biofouling from Ultrafilters
Q. How do you determine appropriate temperature to clean parts with ultrasonic cleaner? A. In general, every 10C you go up in temperature doubles the cleaning speed. The faster you want to clean the hotter you should get. There are of course some residues, including metal oxides, which become more difficult to clean with higher temperatures. If you suspect or aware that you … [Read more...] about Choosing Temperature for Ultrasonic Parts Cleaning
Q. In your email you mentioned that Solujet and Citrajet have more sophisticated surfactant systems than a competitor's low foaming washer detergent - could you explain a little bit more what 'surfactant systems' are? A. Absolutely! Surfactants, or Surface Active Agents, are compounds that lower surface tension between particles, such as oil and water. In the oil and water … [Read more...] about Advanced Cleaning Mechanisms: What are Surfactant Systems?
Q. The color of our Liquinox is slightly different by lot number. Why is this happening? Is there an issue, perhaps we have done something wrong with storage? A. Do not fear! These color variations are normal. There is a range of acceptable color differences in LiquinoxⓇ Critical Cleaning Liquid Detergent.

Q. We have consulted your continuous exposure compatibility information that was sent to us for one of your detergents on various materials. We were wondering about the details of conditions used in formulating this documented info, such as temperature, detergent concentration, and period of time in which these observations were made. A. It is important to keep in mind that … [Read more...] about Detergent Compatibility Information
