impulse back washing (option)
During normal operating mode of the reverse osmosis system, deposits can accumulate on the membrane
(see
figure 5-1 “Permeate mode / Dialysis operation”) depending on the quality of the supply water.
Depending on their origin, they can cause long-term damage to the membrane, thus reducing the
permeate quality.
Figure 5-1:
Permeate mode / Dialysis operation
In order to increase the lifetime of the membrane, patented impulse back washing (IRS) is carried out at
regular intervals in the EcoRO Dia I/II (HT).
Here, reversing the flow direction loosens the deposits and rinses them out via the concentrate flow
(see
figure 5-2 “Impulse back washing”).
Impulse back washing provides a constant permeate quality and a high production efficiency.
