Frequent clogging problem of the primary RO safety filter
Thread Content
The primary RO feed water from our plant is treated through an ultrafiltration unit; the pores of the ultrafiltration membrane are 0.1 microns, and its ultrafiltration performance is guaranteed. The primary RO safety filter has pore sizes of 5 microns, and the replacement frequency is…
Is the quality of the raw water not very good?
The turbidity is fine; it’s not possible to determine what substance it is. Nothing can be seen visually in the sample, and no precipitate forms even after adding chemicals in experiments
There are usually filters such as quartz sand and activated carbon in front of the security filter – could it be that their filtering efficiency has declined? Or is more flocculation occurring due to the chemicals added before the security filter?
Original poster, has your problem been solved? I’ve encountered a similar issue here as well – there’s a gel-like substance, and the filter elements need to be replaced quite frequently
Biological mucus – available in all four grades at the right temperature! Is there no ultrafiltration? Can the ultrafiltration recovery rate be achieved?
After our V-type filter, there is ultrafiltration at 1 micron, and then RO
