Industrial reverse osmosis (RO) systems need regular upkeep to maintain their performance and Guangzhou VOCEE Membrane Technology Co., Ltd. with 20+ years of R&D and manufacturing experience - provides maintenance knowledge based on product assortments and global service back-up, so that your system supports your business in the long-term.
First, it is vital to pre-treat RO membranes and the addition of pre-treatment solutions offered by VOCEE into your maintenance plan will increase the life of the systems. Connecting RO systems to VOCEE ultrafiltration (UF) systems or hollow fiber cross-flow filters (both products) collects suspended solids, bacteria and organic material in advance of water entering the RO unit- this minimizes membrane fouling and also reduces the need to clean the systems. In maintenance, change UF membrane or filter cartridge according to VOCEE on schedule (usually 612 months, but it depends on the quality of water) to maintain the efficiency of pre-treatment. In high-salt water industries (e.g., coastal manufacturing), pre-treatment of RO units by nanofiltration (NF) systems by VOCEE will reduce salt load, and valve checks every month on NF systems will ensure that no untreated water passes to RO unit and will therefore not cause valve damages.
Then, a systematic cleaning routine that depends on your type of water should be put in place. Unlike generic timelines, VOCEE suggests that cleaning frequency should be adjusted according to actual usage: so a system such as the 200m 3 /D textile wastewater reuse system can have a monthly cleaning goal of pigments and alkaline remnants, whereas seawater RO systems can have a quarterly goal of cleaning to remove salt scaling.
Electrical and mechanical component maintenance should not be neglected. The tailor-made RO systems sold by VOCEE are adjusted to the local voltage standards of 100 or more countries- routinely verify the electrical connections to ensure that you do not find short-circuit which stops the whole system. Inspection of the mechanical components such as pumps and valves should be made after every six months. When using big skid-mounted or containerized system, VOCEE remote video guidance can be used to verify component alignment, eliminating unnecessary service delays on site.
Lastly, VOCEE has very clear technical documentation which is a roadmap of constant maintenance and usage of these documents avoids mistakes. Its system documentation contains step-by-step instructions on most common operations such as membrane cleaning (e.g., recommended chemical concentration, time required to clean) and the replacement of parts -adherence to these instructions is guaranteed by the fact that the product will be operated in accordance with the specifications of VOCEE which will not lead to their damage. Process flow diagrams (PFDs) of each RO system are also provided by the company to reflect on the main points of the maintenance (where filters are, where pressure gauges are, etc.) and have the maintenance teams train on them, all of the significant elements are inspected in the course of routine maintenance.
