Lab-Scale CCRO Testing: Screening Waters and Antiscalants on Small Samples

At a glance. A Tech Inc. CCRO Lab Test Skid runs the same closed-circuit cycle as a pilot, on one 2.5- or 4-inch element and a few hundred litres of water.

What it is used for

• Finding the recovery at which a water starts to scale.

• Comparing antiscalants and doses.

• Screening membranes for flux and rejection at high recovery.

• Preparing a pilot test plan.

Good practice

• Keep temperature steady with a chiller.

• Repeat each test at least twice.

• Log every cycle, not just the end point.

Frequently asked questions

How much water is needed? Typically 100 to 500 L per test.

Can it run conventional RO too? Yes, with the flush valve held open.
