From Coupon to Element: Using Spiral-Wound Test Housings for Scale-Up

At a glance. Elements behave differently from coupons: longer channels, glue lines and permeate tubes all matter. Tech Inc. Spiral-Wound Element Test Housings take 1812 to 4040 elements in SS316 or FRP.

A simple scale-up path

1. Screen membranes in flat cells.

2. Roll a small 1812 or 2540 element.

3. Test it in a housing on a pilot skid.

4. Confirm with 4040 elements before design.

What to specify

• Element size and number in series.

• Pressure rating: RO or NF.

• Side or end ports to suit the skid.
