Water – What are ions and ion exchange all about?

Any discussion of water quality and the purification of water will eventually gravitate to a discussion of ions.  Adding ions and/or removing ions using what is called an ion exchange process is a big and essential part of most water treatment.  Let’s take a few minutes to understand basically what these important things called ions are …

Ultrasonics – How to Degas Liquids

A previous blog Ultrasonics – Degassing – What Gas? and Why? revealed why dissolved gas is detrimental to ultrasonic performance.  This blog will describe various ways in which dissolved gas can be minimized and eliminated to facilitate ultrasonic cleaning.  Since the most common liquids used in ultrasonic cleaning are water and water-based solutions, the following applies …

Cleaning – Solvents – So What’s Different Now?
