I have a two-stage reverse osmosis water purifier, the raw water is 70, the first out of 35 pressure 0.8MPa, the second out of 10 pressure 0.8MPa please ask is that out of the problem!

Typical reverse osmosis membrane oxidative degradation, precision decline, must be replaced with a new membrane. Precision has fallen, if the membrane is cleaned what is the use of it, cleaning can not restore precision. Cleaning can only be blocked to effectively restore the output.

Additionally, from your first and second level operating parameters, your second level reverse osmosis equipment performance manufacturing is not good, therefore, it can be predicted that the second level reverse osmosis equipment configuration is extremely simple, not up to the effective protection of reverse osmosis membrane is damaged by degradation.

Of course, we can't rule out a rupture in the seal of the equipment to bring about the cause. However, the first seal problem, it is not possible to bring the second also have problems. Therefore, the possibility of seal damage is very small.
