Troubleshooting for Reverse Osmosis Plant Systems |
![]() |
Troubleshooting Guides - Reverse Osmosis Chemicals International have compiled a series of troubleshooting guides for the operation of reverse osmosis plant systems. Each article deals with some of the more common problems and failures associated with the operation of reverse osmosis systems. Subjects covered include common failures to reverse osmosis systems, replacement of RO membrane elements, O-ring replacement, probing, profiling an RO array and shimming. To review a guide please select the required document link. Common reverse osmosis system failuresReview the most common failures affecting reverse osmosis systems, their effects and recommended monitoring practices. Issues covered include failure of scale inhibitors, ineffective sanitization, excess iron content, high organic content, overdosing of coagulants, acid dosing ... common system failures >> Replacing membrane elements
Replacing O-ringsMovement of the spiral wound reverse osmosis membrane elements within their pressure vessel can commonly cause abrasion and failure of the O-Rings that seal the inter-connector to the element permeate tube. A sudden increase in permeate conductivity, not accompanied with a noticeable increase in permeate flow rate could indicate ... replacing o-rings >> ProbingData probing is a technique used to help identify problems affecting reverse osmosis systems. Once profiling has isolated a salt rejection problem to a particular pressure vessel, or set of vessels, probing can be used to further isolate the problem. Probing involves inserting flexible tubing through one of the vessel permeate connections as a means of diverting the permeate from a specific area within the elements. This water is then tested for conductivity ... probing >> Profiling an arrayWhen problems arise with a reverse osmosis system, the ability to isolate the problem to a particular location within the system provides valuable information as to the precise nature of the problem. This will help to determine the remedial action which may include cleaning, O-ring replacement, RO membrane element replacement ... profiling an array >> Shimming
