Unidro staff is presently engaged in the start-up of three Produced Water Treatment Plants in Hassi R’Mel, Algeria. This is by far the largest active gas production area in Algeria. “Boosting Phase III”, a project awarded to JGC corporation in 2016, is approaching the completion phase. Unidro is working in three different sites in the same gas field (North, Center, South) and all plants are going in operation at the same time; start-up has been successful and Unidro field team, supported by our process specialist in Milano HQ, are now fine tuning all the operating parameters to prepare for the Final Acceptance Test and handover to Sonatrach, the End User expected within 2021.
