Solution to high TDS value of reverse osmosis water purifier

Sep 13, 2020

Regarding the problem that the TDS value of the RO reverse osmosis water purifier cannot be reduced, the following aspects also need to be checked:

(1) First check the TDS value of the raw water, the general RO membrane desalination rate is 90%;

(2) If it is a newly replaced reverse osmosis membrane that needs to run for 20 minutes, then measure;

(3) Confirm whether the pure water storage time in the water storage bucket is too long;

(4) If the rear activated carbon is newly replaced, it also needs to be washed;

(5) When measuring pure water quality, please measure from the reverse osmosis membrane pure water port;

(6) After eliminating the above reasons, you can consider replacing the RO reverse osmosis membrane.
