Cleaning Biologically Fouled Resins

Evaluation of cleaning efficacy of oil fouled cation softening resins. Presented at IWC in 1994.

Application advice for the use of anion resins to remove naturally occurring organic matter (NOM). Written by MG for Water Technology Magazine in 1999.

The rinse bath for plating gets contaminated through the finishing operation, but that doesn’t mean it has to go down the drain. Frank Desilva talks about closing the loop.

Countercurrent regeneration is a method that has tried unsuccessfully to get into the mainstream of the water softening industry. Despite various application strategies, it’s often dismissed as too complex and with little value in brine savings. Time will tell if other issues such as salt and the environment make the technique practical.

Fundamentals of ion exchange technology

New rules released late last year from the Food and Drug Administration (FDA) on water purification for kidney dialysis patients will have a big impact on portable exchange deionization (PEDI) tank services. The quality control focus requires much documentation.

Ultrapure water production by the use of mixed bed ion exchange resin. Factors that influence ultimate quality are presented and discussed.

The history of PFAS, measurement techniques and removal methods.

Procedures and standards to incorporate in the operation of a portable exchange DI regeneration plant.

Hardness minerals, calcium and magnesium, as well as some other dissolved ions, will leave spots on rinsed surfaces if the water is allowed to dry. Here’s how to prevent it from happening.

The ResinTech story.

When to replace anion exchange resin due to oxidation, fouling, or other reasons.
