The JetSplash® technology developed by Membion reduces the energy required for module aeration by up to 90 %. It is so effective that a “permeate backwash”, which is common for many MBR modules, can be dispensed with.
In MBR membrane filters, the sludge particles retained by the membranes are usually flushed out of the filter by introducing air bubbles (air bubble flushing).
For this purpose, conventional membrane filters require a large volume of air and therefore have a high energy demand.
The flushing effect is based on the shear force of the 2-phase flow of air and liquid.
In order to improve the cleaning effect of air bubble flushing, the membrane filters are often additionally backwashed at intervals with water that has already been filtered (permeate backwashing), which increases the membrane area requirement.
Membion has developed a very effective and energy-saving aeration technique for the membrane filters with a novel JetSplash® effect. This requires a significantly lower volume of air.
To achieve the JetSplash® technology effect, a geyser element is installed below each membrane element, into which air flows continuously.
The air leaves the geyser element in regular pulses and is injected directly into the membrane element installed above it and accelerates all the liquid in the membrane element.
This flushes the sludge particles out of the membrane element much more effectively.
