Spray Under Immersion – Like a Jacuzzi!
Liquid motion within and around a submerged part is one of many ways of enhancing both cleaning and rising processes. In an earlier blog, The BIG Four agitation was described as one of the “big four” variables having a major impact … Continue reading
Water – DI vs. RO
Preceeding blogs have described two ways of reducing the ionic content of water for use in washing and rinsing applications. Although both reduce ionic content, the process commonly called “De-Ionization” uses a treated resin to capture ions while the “Reverse Osmosis” process … Continue reading

Water – Reverse Osmosis
Preceeding blogs have discussed de-ionized or ”DI” water, its benefits and its uses at some length. Today’s blog will discuss “Reverse Osmosis” water otherwise known as “RO” water. RO water is like a second cousin of de-ionized water. In the de-ionization process, … Continue reading

Water – De-Ionoized – Right and Wrong
This blog explores some common mistakes made in the application of de-ionization hardware. Although a properly engineered and installed de-ionization system will prevent these potential mistakes at the start, post-installation modifications by those less knowledgeable about de-ionizing technology don’t always … Continue reading

Water – De-Ionization Process
There are many ways to de-ionize water. Some are small and simple while others are large and complex. The method used is determined by the volume of de-ionized water required and the desired purity. This blog will explore some of … Continue reading

Valves – Backpressure Regulating Valves
Pressure regulating valves were discussed in the preceding blog Valves – Pressure Reducing Valves. Pressure reducing valves, although commonly used where pressure is an issue, are not always the best alternative. The pressure reducing valve has a close cousin called … Continue reading
Cleaning and Rinsing – Spray Nozzles for Use in Air
Previous blogs have suggested the use of liquid sprays in air as either a primary mechanism or as an enhancement to both cleaning and rinsing operations. Today’s blog will discuss, briefly, what is important in choosing a spray nozzle or … Continue reading
Rinsing – Better Rinsing Using Less Water
It is no secret that good cleaning followed by poor rinsing can be worse than not rinsing (or cleaning) at all. A single-use rinse using a fresh water spray or a high flow rate or single use immersion rinse are often … Continue reading
