Commercial/Industrial RO Sizing Workshop

The Commercial/Industrial RO Sizing workshop is coming online in a series of interactive problem-solving sessions.

Taught by Peter Cartwright, MWS, PE, this popular workshop, typically offered only at WQA’s annual convention, is coming to a Zoom meeting near you. Practice calculating multiple variables associated with RO system sizing with expert guidance and in small groups with peers.

The workshop will consist of six weekly sessions, 90 minutes each, focusing on worked examples and hands-on practice. Each session will address an aspect of RO system design to meet final system specs that include % recovery, permeate quality, feed flow rate, blending, number of RO elements needed, and required pump pressure.

WQA-certified personnel can earn up to 0.15 CPD per session when attending live webcasts.
