Recycling greywater


Greywater is soapy water from washbasins, showers and baths.
These waters are low loaded and not greasy (the waters from kitchen are excluded).
Thanks to our Micro-clear® recycling technology, all these waters can be used a second time.
Therefore, 50% of the needs usually provided by the city network can be satisfied by recycled water. This includes all needs that do not require drinking water (non-corporeal and non-food).
Depending on the size of the installation, recycling from 1m³ to 150m³ / day of greywater from showers and washbasins for reuse in toilets, surface washing or watering will be possible.

Unlike other resources which are less regular, greywater has a regular volume throughout the year.
Seasonal variations in volume are usually proportional to needs.
The volumes of treated water are exempt from sanitation taxes.
The return on investment is calculated according to the size of the installation and the daily processing volume.


microclear schema de principemicroclearEach module is made up of 24 plastic filtration plates laser-welded to one another. The entire set represents a filtration area of 3.5 m² and is hermetically connected to a filtrate collector.
Depending on required needs, a variable number of modules are stacked and assembled in the frames of different sizes, which also support the aeration system. The latter ensures the cleaning of all membranes.
The principle: Greywater coming from an external source flows through the membrane inside the plate before being sucked towards the filtrate collector by a negative pressure of only 0,1 bar.
Thanks to the membrane pore size of 0.05 μm, particles, bacteria and even viruses are physically blocked!

In summary, our technology combines great security regarding the quality of the filtrate obtained, and reduced maintenance regarding the cleaning of membranes (1 to 2 times per year).


Depending on the project environment, several ways of implementation can be considered.
The system can be buried outside a building or integrated into a HDPE, concrete or even steel tank depending on the daily treatment volume.
