Salt in the Arteries

OrangeBoat Case Study

< >


The operators of a large seawater desalination plant (144,000 m3/day or 38 MGD) were confronted with a mystery: What was causing abnormally high salt passage at their facility? The membrane elements of the RO system were not exposed to chemical damage during operation, and no other problems readily presented themselves. It was truly a confusing situation.

Until the plant operator could find the cause, they were forced to treat the symptom by bringing the second pass online. It performed its function, but at a higher operational cost and at lower production levels. This is a bad situation that no water treatment plant deserves to go through.

Our customer needed an accurate diagnosis and effective treatment plan. For that, it turned to OrangeBoat Support. We took the helm and guided our client to prosperity.


OrangeBoat carried out a comprehensive plant audit. It included a site visit and detailed review of operating data, equipment, operation and maintenance practices, as well as an evaluation of RO membrane elements.


OrangeBoat proved that mechanical damage of the RO membrane elements had caused the high salt passage. OrangeBoat pinpointed the source of the problem, enabling the operator to initiate a dialogue with the membrane element manufacturer.  Based on OrangeBoat’s audit report, the operator was able to convince the membrane element manufacturer to replace 20% of the installed membrane elements at no cost to the operator. Upon restart, the facility easily met its goals for water quality and production levels.
