Waste water - Example 7
Waste water after UF and RO
Waste waters are sometimes re-used for technical purposes (reclaim) and membrane techniques are the state-of-the-art.
Here, the product water after RO had a TOC-value of only 50 ppb, but severely fouling of the RO membrane was observed.
The RO permeate showed biopolymers which sows that biofouling did not occur on the high-pressure side but the low-pressure side.
