If RO membrane production falls, will direct membrane replacement solve it? Review feedwater, operating and pretreatment records before assessing the cause, so procurement has a firmer basis.
Information preparation and assessment basis
For an inquiry, first take clear photographs of the brand, complete model designation and specifications on the old membrane or original documentation. Then state the number in use, equipment use and planned purchase quantity. Similar-looking membranes do not necessarily have the same operating conditions or performance requirements.
Also provide recent production, pressure, temperature, relevant feed and treated water parameters, and when the abnormal condition began. Before-and-after records are helpful if available. Do not attribute every problem to an old membrane.
Technical staff will also check pretreatment, instruments and operating conditions. Decide whether cleaning, operational adjustment or replacement is needed according to the membrane manufacturer's requirements and site circumstances. Do not freely copy online cleaning methods or chemical formulations.
After confirming procurement, record the supplied brand, model, quantity, delivery scope and applicable conditions in the documents. For an alternative model, ask the supplier to explain the basis clearly before deciding whether to adopt it.
We provide membrane and related consumable compatibility consultations. Use the inquiry channel available on this page and provide redacted nameplate photographs, intended use and purchase quantity as requested. If information is insufficient, technical staff will list what is still needed.
