Commercial/Industrial RO Sizing Workshop

The popular Commercial/Industrial RO Sizing workshop, once offered only at the annual WQA Convention, is now available online in a series of interactive problem-solving sessions.

Taught by Peter Cartwright, MWS, PE, the workshop allows participants to practice calculating multiple variables associated with RO system sizing with expert guidance and in small groups with peers.

The workshop will consist of seven weekly sessions, 60 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 0.10 CPD per session when attending live webcasts. Attend all seven and you'll earn 0.7 CPD of the 2.0 to 3.0 CPD required for recertification.
